Category: Solar 101

Misinformation can spread like wildfire, and it’s no different in the field of solar. You may hear it at an afternoon barbecue or stumble upon it online. And even I, who’s been in the solar industry for quite a while now, have come across things that even made me do a double take. But don’t let these misconceptions sway you. Otherwise, you might end up passing on an opportunity that could significantly lower your bills and save you money. In this article, I’m setting the record straight by exposing some of the biggest solar myths out there and uncovering interesting facts that all homeowners must know.

Myth 1: Solar Panels Don’t Work in Cloudy or Cold Weather

It doesn’t matter whether it’s cloudy or cold. Your panels will continue working in these conditions as long as sunlight is available.

Although not immediately obvious, sunlight still makes its way through the atmosphere on  overcast days, which your panels capture and convert into electricity. However, production naturally dips since diffuse light isn’t as intense as direct light on clear, sunny days.

When it comes to temperature, you might be surprised to know that solar panels perform better in the cold. In fact, one study finds that solar panels can experience a 25% reduction in efficiency when exposed to extremely high temperatures.

And if you’re wondering how practical solar actually is in colder regions, consider this — New York, Massachusetts, and New Jersey are among the top solar adopters in the U.S. according to the Solar Energy Industries Association (SEIA).

Myth 2: Solar Panels Will Damage My Roof

If you really think about it, the opposite is true. Solar panels shield your roof against direct sunlight, heavy rain, and other harsh weather conditions. In that sense, they actually extend your roof’s lifespan.

Still, I understand the worry about roof damage. Seeing holes drilled into your roof and mounting hardware secured in place can definitely make it seem like a leak is inevitable.

But here’s the thing: Roof leak due to solar panel installation is extremely rare, especially when handled by a professional.

In fact, I’m proud to say that the Avail Solar team has never received angry calls from customers about leaks. 

I’d guess the same is true for other reputable installers as well. We’re all trained to follow local codes and guidelines to make sure your roof stays secure during and after installation.

And as a bonus, since your roof remains undamaged, your roof warranty won’t be voided and will stay valid.

Myth 3: I Need to Replace My Entire Roof Before Going Solar

Most modern homes have roofs that are more than capable of supporting solar panels. Roofing materials like asphalt shingles, metal, and tiles typically have lifespans of 20 to 50 years, which is well in line with a solar panel system’s expected lifespan. 

So, chances are, you won’t need to replace your entire roof.

Although, there are indeed some roofs designed with shorter lifespans, such as rolled roofing or composite shingles, which may only last 10 to 15 years. In this case, it’s highly recommended to replace your roof, especially if it’s nearing the end of its lifespan.

Ultimately, there’s no need to worry too much about your roof. Apart from the fact that it’s likely to support your panel’s weight just fine, it’s our job as solar installers to inspect your roof before installation and confirm that it’s suitable for solar.

Myth 4: Solar Will Make My Home Look Ugly

What if I told you that homes with solar panels tend to sell for extra — about $9,000 more on average? Well, that’s what a study by Zillow, a reputable real-estate marketplace, found.

Not so ugly anymore, right?

That being said, solar doesn’t reduce property value. Rather, it boosts it.

On top of selling higher, it also makes your home sell faster.

In fact, a report from the American Council for an Energy-Efficient Economy (ACEEE) finds that homebuyers tend to choose homes that explicitly mention energy-saving features.

They simulated a real estate website and found that listings promoting energy-efficient features attracted more potential buyers.

And this makes sense. Homebuyers see energy-saving upgrades like solar panels as valuable additions that reduce long-term costs. 

Now, if you’re really worried about aesthetics, know that today’s solar panels are no longer the clunky, bulky hardware they once were. Instead, most of them are sleek, all-black designs that blend well with most modern roofs, adding something of a designer’s touch to your home.

Myth 5: Solar Only Works on South-Facing Roofs

South-facing roofs are the best in the U.S. because they stay aligned with the sun’s path throughout the day, ensuring maximum sunlight exposure and, in turn, better energy production.

That said, this doesn’t mean solar panels on other roof directions won’t work. In fact, in a previous article I wrote, I explained how combining south- and southwest-facing panels can often yield the best results.

Individually, though, this is how it pans out…

East-facing roofs receive more sunlight in the morning, while west-facing roofs get more sun in the afternoon. North-facing roofs, meanwhile, get the least sun exposure, so they naturally have the lowest energy production.

Bottom line is that, as I mentioned when discussing Myth 1, solar panels will generate power as long as there’s sunlight, regardless of which direction your roof faces.

Myth 6: I Won’t Save Much Because My Energy Bills Are Already Low

If you’ve kept a tight handle on your electricity spending, props to you! That’s no easy feat.

But here’s something to think about. If you’ve already mastered managing your energy use, imagine how much more you could be saving with the right setup in place. What do I mean by this?

Bear in mind that electricity rates rise at an average of 2-3% per year. Meanwhile, with solar, you’ll be paying a predictable, flat rate for the energy you consume. If we crunch the numbers, this is how it could play out:

**Based on an average monthly consumption of 899 kWh at $0.16/kWh, with a projected 3% annual increase reflecting typical U.S. utility rate inflation.

**Assumes a $17,000 system with a 30% federal tax credit applied, resulting in a $1,200 fixed annual payment over 20 years at 5.99% interest.

As you can see, you could be missing out on thousands of dollars in solar savings if you stick with traditional electricity.

Myth 7: There’s Such a Thing as “Free Solar Panels”

“Free solar panels” is just a marketing ploy designed to grab attention.

It’s what solar companies often use to aggressively promote solar leases or power purchase agreements (PPAs) — options that typically require no upfront payment — hence the term “free.”

Unfortunately, it’s far from free, because you pay for it in other ways.

For one, these contracts typically lock you into long-term agreements that stretch 20 years or more. Plus, since you don’t own the system, selling your home can become much more complicated.

I’m not a big fan of these options myself because, oftentimes, homeowners in such arrangements often end up searching for ways to get out of a solar panel contract.

Whenever possible, better buy your panels outright or at least finance them. This way, you’ll own your system and enjoy the most savings in the long run.

Myth 8: Solar Panels Require Constant Maintenance

Solar panels are basically a one-and-done investment. Once installed, they quietly go about their job with very little effort on your part.

In fact, we installers really only get called out for major panel issues like hardware or wiring damage. And that’s usually just once in a blue moon.

As for cleaning, rain often does a good job of washing away dust and debris. But if you live in a dusty or pollen-heavy area, we recommend giving your panels a quick rinse (it’s as simple as running a garden hose over them) from time to time.

Myth 9: Solar Power Doesn’t Work During Power Outages

Well, this is technically true — unless you have a solar backup battery.

Most homeowners have grid-tied solar systems, which automatically shut off during power outages for safety reasons. 

However, if you have a backup battery with enough charge stored from your panels, it can kickstart your home’s power and keep essential appliances running, including your solar system.

That said, while solar batteries aren’t mandatory, they definitely add value.

Myth 10: Solar Energy Doesn’t Work at Night

Solar panels don’t work at night — but solar energy does. How? Through solar batteries or net metering.

Solar batteries can store excess energy your panels produce, which you can consume for nighttime use.

On the other hand, net metering is an arrangement where your utility company rewards you with “energy credits” for excess energy sent back to the grid. These credits can offset your electricity use at night.

Myth 11: I Need a Special Insurance Policy to Cover My Solar Panels

In most cases, adding solar only requires a simple update to your home insurance policy — no need to get an entirely new one.

Most insurers include solar systems as part of your existing homeowner’s policy, often with little or no extra cost.

However, things can be different if your panels are installed on the ground or mounted on secondary structures like sheds or garages. In such cases, your coverage might be lower, or you may need to purchase additional coverage (sometimes called riders) to ensure your system is fully protected.

I’ve discussed this in more detail in the article Are solar panels covered by home insurance.

Myth 12: Homeowners Will Have No Electricity Bills After Installing Solar

For starters, you’ll still have an electricity bill if your home solar system is designed to cover only part of your grid usage.

But even if your solar panels are built to cover your entire energy consumption, your utility will likely still require you to pay grid connection fees or other fixed charges for maintaining your access to the power grid.

Myth 13: HOAs Prohibit You From Installing Solar

Many states have “solar access laws” that protect homeowners from HOA restrictions. While your HOA may have guidelines about system placement, they often cannot prevent you from installing solar altogether.

Wrapping Up

Going solar is one of the biggest decisions you can make, and separating fact from fiction can make all the difference.

Generally, yes – solar panels are covered by homeowners insurance. And that’s a huge relief because the last thing you’d want is to pay out of pocket for unexpected damage, which can be a costly headache. But how much coverage you get depends on how your solar panels are installed.

• If your solar panels are attached to your roof (and you own them, not leased), they’re typically covered in full under your dwelling coverage. That’s because your insurance treats them as a permanent part of your home, just like your roof itself.
• If your solar panels are installed separately from your home (e.g. ground-mounted panels or panels on a detached garage), your insurance *might* still cover them.

Do Solar Panels Increase My Homeowners Insurance Premium?

In most cases, yes, adding solar panels to your home can raise your homeowners insurance premium. 

Remember, your insurance provider originally valued your home before you installed solar panels. 

And since adding a solar energy system isn’t exactly a minor upgrade, costing around $15,000 to $25,000 after tax credits, it increases your home’s value and, in turn, the insurer’s risk – which can lead to higher premiums.

If your current coverage isn’t updated to reflect this addition, your policy might not fully cover the cost of repairs or replacement in case of damage.

Now, does this mean your premium will always go up? Not necessarily. Many homeowners have added solar without seeing an increase in their rates. But from what I’ve seen, that usually comes down to two things:

• They contacted their insurer and confirmed that their existing coverage is already enough to protect the new solar panels (this is the ideal scenario).
• They assumed their policy covers their panels without checking with their insurer.

You don’t want to be part of the second group. If you assume you’re covered but actually aren’t, you could be in for an expensive surprise if something happens to your property and your insurance comes up short.

That’s why calling your insurer right after installing solar panels should be standard procedure. 

Ask if a premium adjustment is needed or if you’ll need a policy endorsement or rider to cover your panels. Your provider will walk you through the next steps and any paperwork needed to finalize your policy update.

What Issues/Events Does Home Insurance Cover?

Your standard homeowners insurance likely covers your solar panels against certain unexpected events. According to the Insurance Information Institute, these typically include:

• Fire or lightning
• Hail or windstorm 
• Explosion
• Riot/civil commotion
• Vandalism or malicious mischief
• Theft

But just as there are covered events, there are also situations where your standard policy may not apply, or might require additional coverage, such as an endorsement or an entirely separate policy:

• Floods
• Earthquakes
• Hurricanes
• Damage caused during solar installation or due to lack of maintenance

That last point is a big one.

If your solar panels are damaged because they weren’t installed properly or maintained well, your insurer may deny your claim. That’s why working with a reputable solar installer and staying on top of routine maintenance is just as important as having coverage in place.

Bear in mind that these are general guidelines. Your specific policy may have certain conditions, exclusions, or special clauses that affect coverage. The best way to know exactly what’s included (and what’s not) is to contact your insurance provider directly.

How do I File a Home Insurance Claim for My Solar Panels?

The fastest way to file a home insurance claim for your solar panels is pick up the phone and call your insurance company. This way, you’ll have clear instructions on what to do next.

The exact process will depend on your insurer, but expect to:

• Be asked to explain details of the incident, including when it happened and the extent of the damage.
• Submit documentation, like photos of the damage, installation details/agreement, etc.
• Follow additional instructions, like paperwork and submission deadlines

Many insurance companies also allow you to file a claim online or through their mobile app. If your provider offers this option, you may be able to upload photos, submit documents, and track your claim status without making a phone call.

If I Leased My Solar Panels, Who is Responsible for Insuring Them?

If you leased your solar panels, the leasing company will be responsible for insuring them, not you. Since they own the system, it’s their insurance policy that applies in case of damage or loss.

That means you don’t need to add them to your homeowners insurance.

However, I’d still recommend checking with your solar provider first. You might have missed details in the fine print, and there could be a clause requiring you to carry a certain level of coverage.

Does Home Insurance Cover Roof Damage From Solar Installation?

Your homeowners insurance may or may not cover roof damage caused by solar installation – it all depends on your policy’s terms.

The good news is, if your system was installed by a certified solar installer, their own solar panel warranty will likely cover the repairs at no cost to you. For example, we at Avail Solar offer a 30-year workmanship warranty, which includes coverage for roof penetrations.

But the even better part? When you work with a certified installer, the risk of roof damage is minimal to begin with. They know exactly how to secure your panels without compromising your roof’s structure, so you won’t have to stress about leaks or long-term issues.

What to Do If My Insurer Refuses to Cover Certain Types of Damage to My Solar Panels?

If your insurer refuses to cover specific types of solar panel damage, here are some things you can do:

• Check if your insurance offers riders or endorsements to extend the coverage to solar panels. If available, ask about the cost and whether it makes sense for you.
• Consider purchasing a standalone solar insurance.
• Switch to a better homeowner insurance provider, especially if you find your current provider to be too restrictive.

Final Thoughts

In most cases, your standard homeowners insurance will cover your solar panels. And with that being almost always a given, what you really have to figure out is whether your existing policy is enough to protect your entire solar-powered home if the worst happens.

That’s why reaching out to your insurance company should be standard procedure once you go solar. Confirm what’s included in your coverage, ask about exclusions, and make sure you won’t be left paying out of pocket for unexpected repairs or replacements.

And when it comes to your solar system, we at Avail Solar handle everything – from design and installation to long-term maintenance – so you enjoy a smooth, hands-off transition to solar while your panels keep cutting your electric bills for years. Get a quote or call us today!

Solar panel warranties protect your investment and keep your system running for decades. In fact, many manufacturers guarantee performance for 25+ years! But here’s the thing: warranties aren’t a free pass for every issue. There are fine-print conditions, gray areas, and actions that could void your warranty completely.  And If you don’t know what to watch out for, you could end up paying out of pocket for repairs you thought were covered. Read this guide to learn exactly what’s covered and what’s not, and the answers to some of the most frequently asked questions about warranties, so you can transition to solar with confidence.

What Issues are Covered in a Solar Panel Warranty?

The issues covered by a solar panel warranty depend on the type of warranty that applies. These include:

Product Warranty

A product warranty protects you against manufacturing defects and material failures in your solar panels. Physically, these issues can appear as:

• Glass delamination, where the panel’s outer layer starts separating
• Hot spots, which are burn marks from uneven electrical currents.
• Other defects that show up, like cracks, frame warping, or faulty junction boxes

If you suspect a defect, the manufacturer will typically ask for proof before approving a claim. They may request photos, a description of the problem, and, in some cases, an inspection by a technician.

Once they confirm the defect, they’ll then offer a replacement panel or a repair service usually at no cost. Some manufacturers might also cover labor costs, but this varies by warranty terms.

Performance Warranty

The other type of warranty that comes from purchasing your solar panels is the performance warranty. This protects you if your panels produce less energy than they should based on the manufacturer’s guaranteed performance over time.

For context, most manufacturers expect a 0.5% to 0.8% degradation rate per year, which means that after 25 years (i.e. the typical solar panel lifespan), your panels should still produce energy at roughly 80 to 90% of their original capacity.

If your system underperforms beyond the expected rate, they’ll typically repair or replace (whichever applies) the affected panels.

Bear in mind that a performance warranty does not apply if your panels are simply not producing at full wattage on a given day – that’s a different story. Energy output fluctuates due to factors like weather, shading, and time of day, which aren’t considered material- or workmanship-related problems.

Installation / Workmanship Warranty

A solar installation warranty, also called a workmanship warranty, is different from product and performance warranties. Instead of covering the panels themselves, this warranty protects you from faults or defects in the installation process, such as:

• Loose or misaligned panels, which reduce production efficiency
• Faulty wiring, which may cause electric failures (and in rare cases, solar panel fires)
• Leaks around the mounting points, which can happen if the installer didn’t properly seal the penetrations in your roof (especially on asphalt or corrugated metal roofs)

That said, this protection is provided by the professional solar installer who sets up your system (just as we do at Avail Solar) and not your solar panel manufacturer.

That also means, if you install your solar panels yourself, you won’t have this type of protection, and any installation mistakes or damage will be your responsibility.

Fortunately, many states, cities, and HOAs require professional installation as part of the permitting process to meet safety and building standards. So, if this applies to you, your system will indeed come with a workmanship warranty.

What Issues are NOT Covered by Solar Panel Warranties?

From my own observations, these are some of the most common issues that solar warranties don’t cover:

• A guarantee of a specific energy output: Your solar panel’s actual production depends on factors like weather, shading, and system maintenance, so manufacturers don’t promise a fixed amount of electricity generation.
• Damage from extreme weather or unexpected events: This includes hail, hurricanes, floods, accidental breakage, and theft, among many others. Your homeowner’s insurance might cover this instead.
• Routine maintenance: Keeping your system in shape, such as cleaning panels or checking electrical connections, is your responsibility. However, if you have a professional installer handling the job, some (like us) include maintenance as part of their post-sales service.

There are also some gray areas where coverage depends on the manufacturer:

• Labor costs and truck rolls: Some brands cover full labor costs, including diagnosis, repairs, material replacement, and shipping. Others may only cover diagnosis or material replacement, leaving you to pay for reinstallation. Some even offer full coverage but with a cap.
• Damage from salt mist exposure: If you live near the coast, salt mist can cause panel corrosion over time. Most modern solar panels are resistant to this, but it’s worth checking whether your warranty explicitly includes or excludes it.

Now, these exclusions generally hold true, but I strongly recommend reading the fine print, as the warranty terms will lay out the specific conditions under which an issue is covered or not. If unsure, don’t hesitate to ask your solar provider to clarify.

How Long Do Solar Panel Warranties Last?

Generally speaking, solar panel warranties last for the following periods:

• Product Warranty: 10 to 25 years
• Performance Warranty: 80 to 92% efficiency after 25 years
• Workmanship Warranty: Often 5 to 10 years

However, exact coverage periods depend on the brand/solar company.

To give you an idea, here’s a look at the product and performance warranties offered by some of the top solar panel manufacturers, including those we install at Avail Solar:

As you can see, some manufacturers, like VSUN, offer a massive 40-year product warranty, while others, like Silfab, provide only 12 years – unless you use a Silfab-certified installer, in which case the warranty extends to 25 years.

Again, as boring as it might be, those little asterisks in the fine print matter. Warranty terms spell out exactly what’s covered – and just as with Silfab’s extended warranty for certified installers, small details can make a big difference.

Now, how about workmanship warranties?

As I mentioned, workmanship warranties typically last around 10 years, though this varies by company. Some offer as little as 3 years, while others go beyond the average. 

For example, we at Avail Solar offer a 30-year Bumper-to-Bumper Workmanship Warranty, which means full coverage for any installation-related defects.

How to Submit a Solar Panel Warranty Claim

If you notice an issue with your solar system, the first step is to contact your solar installer as soon as possible. They’ll guide you through the next steps, which usually include providing a verbal description of the problem, submitting photos or video evidence, and filling out a warranty claim form.

Alternatively, you can check your manufacturer’s website for contact details and specific claim procedures if you prefer to review the process before reaching out.

Expect that, if necessary, the manufacturer or installer may send a technician to inspect your system and confirm the issue. Once verified, they’ll walk you through the next steps, whether that’s a replacement, repair, or other resolution under the warranty.

If you installed your solar system DIY, you’ll likely need to contact the manufacturer directly.

In this case, they may authorize some claim and, if necessary, they’ll often refer you to a certified technician or a partner service provider for further assessment.

And here’s one thing I always remind solar customers of – and you should definitely keep in mind too: Don’t delay making that claim call. Waiting too long might make the issue worse and lead to additional damage that your warranty won’t cover.

Are There Additional Costs Involved When Claiming a Solar Panel Warranty?

In some cases, yes, there may be additional costs when claiming a solar panel warranty.

These typically revolve around labor and service fees, particularly for troubleshooting, truck rolls (the cost of sending a technician to your home), and reinstalling replacement equipment.

That said, it’s hard to pin down an exact number for these costs. Rates vary depending on your solar installer’s pricing structure, the extent of the repair work, and truck roll fees, which fluctuate based on distance.

Because of this, I’d say this is one of the top questions to ask a solar company before committing. This will help you avoid unexpected costs down the road.

What Can Void a Solar Panel Warranty?

Aside from the issues that aren’t covered under warranty, certain actions may void your solar panel warranty altogether. Here are some examples:

• Failure to register the warranty (some manufacturers require you to register your warranty within a certain timeframe after installation)
• DIY installation
• Unauthorized modifications of solar components (e.g. adding unauthorized third-party hardware, system tampering, etc.)
• Removing or relocating panels
• Transferring ownership (if the terms specify it)

What Happens to My Warranty if My Solar Company Goes Out of Business?

If your solar company (i.e. solar installer) goes out of business, your manufacturer warranties – product and performance – will still be valid. Since these warranties come directly from the manufacturer, not the installer, you’ll be dealing with the manufacturer directly for any claims.

However, your workmanship warranty disappears with the installer. 

If any installation-related issues arise, you’ll likely have to pay out of pocket for repairs that would have otherwise been covered. Some manufacturers may refer you to one of their certified partners, but labor costs will be your responsibility.

In some cases, if a new company buys out your original solar installer, they might choose to honor existing workmanship warranties – but this isn’t always a guarantee as it depends entirely on the new management. 

That means, if they don’t assume warranty obligations, you’ll remain responsible for any future repair costs.

Can I Transfer My Solar Panel Warranty?

If you’re moving and selling your home with solar panels, you might be wondering whether your solar panel warranty can be transferred to the new homeowner.

For most brands (including those we install at Avail Solar), the answer is yes. However, the process of transferring the warranty varies depending on the manufacturer.

Some warranties transfer automatically (meaning no action is needed as long as the system stays in place), while others require paperwork, proof of ownership transfer, and sometimes a processing fee. So, be sure to check with your solar installer or manufacturer.

Wrapping Up on Warranties for Solar Panels

By now, you know better what solar panel warranties cover, what can void them, and how long warranty periods last. That said, warranties are a crucial factor in choosing the right solar brand and installer, especially when you recall how coverage varies between manufacturers.

When it comes to battery vs generator, here’s my take – both are equally good. In fact, having both would be the perfect setup as each one fills the gaps where the other falls short (and you’ll see how as we go through the details). But for most homeowners, investing in both at once isn’t realistic. If you’re on a budget, you’ll likely have to choose one first. ​​That’s why I wrote this article – to lay out just the facts. I’ll go over every key difference between these backup power options so that by the end, you’ll have all the information you need to decide which one makes the most sense for your home right now.

Cycle Up Time

Cycle-up time refers to how long it takes for a backup power source to turn on and start delivering electricity once the grid goes down.

In this area, batteries have the advantage.

Backup batteries provide an automatic and instant switch, you won’t even notice power outage had taken place. No flickering lights, beeping appliances, or a disconnected Wi-Fi.

If you work from home, rely on medical devices, or just want to cook without interruptions, you’ll want to have batteries as your backup energy source.

Generators, on the other hand, take a while to make the switch.

If you have a portable one, you’ll have to start it manually, and that can mean fumbling with the pull cord in the dark, and sometimes, in bad weather. Even standby generators, which turn on automatically, take around 10 to 30 seconds to detect the outage and power up.

Noise

Batteries don’t make noise as they don’t involve any moving parts like motors, exhaust systems, or cooling fans.

Generators, on the other hand, are built like small engines. Just like cars, they burn fuel, whether that’s gasoline, propane, or natural gas, and that combustion process naturally makes noise.

Some models are louder than others, but even the “quiet” ones still produce a low, steady drone. If you’ve ever tried to have a conversation near a running generator, you know that hum isn’t something you can brush off.

In fact, many HOAs have noise restrictions, and a generator running through the night could get you more than just a few annoyed glances – maybe even a warning letter.

But even if you’re not in an HOA, do you really want to hear an engine rumbling outside your window? As they say, silence is a luxury most people don’t think about – until that generator rumbles and reminds them otherwise.

Power Reliability

This is an area that’s a lot to unpack. But if I had to sum it up, both backup batteries and generators are equally reliable – just in different ways.

Bear in mind that, when we talk about power reliability, what we’re really asking is, how long can each option keep supplying backup power? To compare them fairly, let’s break it down into two realistic matchups instead of making an “apples to oranges” mistake.

Solar-Charged Batteries vs. Portable Generators

A solar battery only stores the energy it captures while the sun is out – and that’s all you get for today until it recharges the next day. If it’s on cloudy days or during winter, the battery may store less energy than usual, meaning you’ll have a smaller backup supply when you need it.

A portable generator, on the other hand, runs as long as you have fuel on hand. If you’ve stocked up on gas or propane, you can keep it going for hours or even days.

But if you didn’t buy enough fuel beforehand, or worse – if you run out in the middle of the night – your only option is to find an open store and hope they still have some in stock.

Since both rely on a finite energy source, they’re equally good for short-term outages. But how much backup power you actually have will always depend on the conditions – whether it’s the weather for a solar battery or your fuel supply for a generator.

Grid-Charged Batteries vs. Standby Generators

Between the two, standby generators have a slight edge in long-term reliability. 

Since they’re connected to a natural gas line, they can run indefinitely without you lifting a finger. A grid-charged battery, however, only has what’s already stored. Once drained, it can’t recharge unless the grid is back.

That said, most outages last anywhere from a brief flicker to a few hours, and rarely do they stretch into days. Both batteries and standby generators can easily keep your home powered in those cases.

Cost

This is another area with multiple layers to peel back because cost isn’t just about the upfront price – although it’s always a good starting point.

Capacity and brand will always influence the cost, but if we talk about minimums, a whole-home 10 kWh solar battery can cost at least $9,000. Meanwhile, a standby generator can start as low as $5,000. 

In this regard, batteries are clearly more expensive than generators.

But the thing is, most homeowners today don’t see batteries as just an emergency backup. They view them as a way to slash those electricity costs, especially when paired with solar panels.

So, if we look at both systems not just as backup solutions but as complete energy independence setups, the picture changes:

• Federal Tax Credit & Rebates: Solar batteries qualify for the federal tax credit, bringing down the cost greatly. Many states also offer rebates that further reduce the price. Generators don’t qualify for these incentives.
• Maintenance Costs: Generators need regular maintenance – oil changes, filter replacements, and periodic servicing. Solar batteries? Virtually zero upkeep once installed.
• Electricity Costs: A solar battery plus solar panel system can reduce your grid reliance to $0 over time (assuming your solar system offsets your full energy consumption) A generator, however, doesn’t cut your electricity costs at all as it only kicks in during an outage.
• Time-of-Use (TOU) Rates: Many utilities charge higher rates during peak hours. Solar batteries store energy when rates are low and supply it when rates spike, saving you even more. Generators don’t store power – they just burn fuel. And on that note…
• Fuel Costs: Generators constantly need fuel, whether it’s gasoline, propane, or natural gas. And with fuel prices fluctuating, that cost adds up over the years. A battery? No fuel needed.

Of course, the actual cost depends on factors like your energy use, local utility rates, and system size. But based on everything we’ve covered, solar batteries offer long-term savings and the potential to cut, or even eliminate, your electricity bill.

Lifespan

If you’re investing in a backup power system, you want to know how long it will last before you need to replace it. Both backup batteries and generators have long lifespans, but how long depends on how they’re used.

Solar batteries, particularly, lithium-ion models (which are popular today),  typically last 10 to 15 years – and that’s assuming daily use as part of your home’s energy system, not just occasional backup power. 

Standby generators, on the other hand, can last anywhere from 20 to even 40 years.

That seems like a clear win for generators, but here’s the thing – they’re only used for backup power, not daily energy storage.

And that’s an important distinction when comparing lifespans because ultimately, the discussion shifts to efficiency over time.

For starters, a lithium-ion battery can still operate at around 70% of its original capacity after 10 years, with little to no maintenance. That’s still very usable if you ask me. 

But a generator at year 40? That’s a big question mark. Because, whether it still produces the same amount of power by then depends entirely on how well you’ve maintained it over the decades.

Size and Space

For many homeowners, it’s not even about cost or reliability but whether there’s room for it. Because, if you live in a subdivision, for example, space limitation is a real factor to consider.

Generators are fairly compact, but they still need a dedicated space outdoors. A standby generator usually requires at least a few feet of clearance from your house, plus enough space for ventilation.

Even portable generators, while smaller, need to be stored somewhere when not in use and then moved outside when needed – but all is fine if you have a large yard. 

Otherwise, you’re better off choosing a solar battery. It is more compact, can be wall-mounted inside your garage or on an exterior wall, and takes up zero floor space.

Health & Safety

Solar batteries don’t pose any health risks because they don’t burn fuel or release emissions. 

Generators, however, do. And this is the case for portable generators, which release carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter as they burn gas, propane, or diesel. In fact, carbon monoxide poisoning is a very big concern for homeowners in the U.S.

Then, there’s the matter of fire risks.

Solar-related fires are extremely rare and are almost non-existent. Generators, on the other hand, deal with highly flammable materials that can cause fires if improperly stored or leaks happen. 

Not to mention, generators themselves get hot when running, and if placed near flammable materials, they can become a fire hazard over time. This is precisely why generators must be placed and operated outside the house.

Final Thoughts on Battery vs Generator

Looking at everything we’ve covered, it may seem like solar batteries have the clear advantage – and in many ways, they do. The facts are just what they are. But that doesn’t mean generators aren’t a solid option.

They’ve been keeping homes powered for decades, and if a traditional backup solution works for you, there’s no reason to change that.

But if you’re looking for a system that not only provides backup power but also cuts your electricity costs, a solar battery + solar panel setup is the way to go.

At Avail Solar, we design and install custom solar setups that can offset your home’s energy consumption, helping you turn those rising electricity bills into long-term savings. We take care of everything, from planning to permits and paperwork, so you can switch to solar hassle-free.

Where your electricity comes from – whether from your own solar panels or straight from the grid – determines how much you pay for power. That’s where the concept of Front of the Meter vs. Behind the Meter comes into play.  These aren’t just buzzwords for describing energy sources. They have a bigger impact on your electricity bills and savings than you might think, especially when it comes to time-of-use rates, net metering, or battery storage. In this article, we’ll take a closer look at what these terms actually mean, why they matter to homeowners, and how FTM and BTM systems compare.

What Is a Behind the Meter System?

A Behind the Meter system is an energy system that generates power right on your property and delivers it directly to your home. That means, the energy produced gets consumed first before your meter ever records anything – hence, behind the meter.

BTM systems work simply and directly. Take the case of home solar systems, which is a BTM system popular among homeowners in Utah and across the U.S.

When the sun is shining, your panels produce electricity that your home uses immediately. If your system is paired with a battery, you can store surplus energy for later use.

Only when your solar production isn’t enough to meet your needs does your home pull electricity from the grid.

Therefore, with BTM systems, you actually buy less electricity from your utility company. And that results in a much smaller monthly bill.

This makes an even greater difference if you’re in a time-of-use (TOU) pricing arrangement. 

Instead of using grid energy during expensive peak hours (typically late afternoon to early evening), you can instead use stored solar power (via solar batteries) or net metering credits you’ve accumulated.

Here are common examples of BTM systems for homes:

• Rooftop solar panels
• Solar Panels + Battery Storage
• Small wind turbines
• Gas-powered generators
• Residential fuel cells
• Microgrids

I looked deeper into BTM systems and found that even U.S. tech giants like Apple and Ikea have installed extensive BTM systems to act as their own power suppliers and cut down energy expenses. So, if it works for them, it can work for you as well.

What Is a Front of the Meter System?

A Front of the Meter system is a power-generation system situated outside your property, operating on a much larger scale and requiring huge infrastructure investment. Think of power plants, solar farms, and wind farms, among many others.

This is the default system most of us rely on – electricity is produced at a centralized location, fed through the grid, and distributed to multiple users. Before reaching your home, it passes through your meter first – hence, front of the meter.

You might be wondering, if BTM systems exist, why do we still need FTM systems? 

The answer is simple. They provide a steady flow of energy when your BTM system isn’t generating enough, a sort of ‘safety net’.

But rather than seeing it as choosing one over the other, think of it as two systems working together to keep a single, larger energy system balanced…

When FTM systems struggle during peak demand, BTM systems help ease the load and reduce strain on the grid. On the other hand, when BTM production is insufficient, FTM systems can fill the gap.

Comparing Front of the Meter vs Behind the Meter Systems

Previously, we looked at BTM and FTM systems separately. Now, let’s take a different approach and compare them side by side in key areas where one clearly stands out over the other.

Immediate Savings on Your Energy Bill

Let’s say you go with solar as your BTM system. A home solar systems can cost as little as $0.08 kWh. 

Compare that to the electricity you buy from an FTM system (i.e. power from your utility company), where the average rate sits at $0.19 per kWh. 

Assuming the typical U.S. household consumption of about 900 kWh per month, installing a BTM system could slash your electricity costs by $99 per month. If you ask me, that’s already a big deal, especially when you look at how much that adds up over time.

Direct Ownership and Local Benefits

When you own a BTM system, you own your power source. And that brings benefits beyond just lower electricity bills.

For example, the solar tax credit, which I covered in my article on Form 5695, allows you to deduct up to 30% of your total solar installation cost from your taxes. You can also take advantage of RECs (Solar Renewable Energy Credits) and rebates from local utility companies.

Now, compare that to an FTM system, like a shared solar farm. You may still get benefits like bill credits and lower rates, but at the end of the day, the third party (i.e. whoever manages the farm) keeps most of the financial perks.

Flexibility in Energy Use

With a BTM system, you control how and when you use your energy.

Under net metering, for instance, if you generate more power than you use, your meter runs in reverse, and you earn credits for the extra electricity. You can then use these credits later to draw from the grid, whether at night or during high-demand hours.

Where net metering setups are unfavorable (California’s NEM 3.0, for example), having a BTM setup that involves adding energy storage (e.g. solar panels + solar battery) lets you store excess power instead of drawing from the grid.

That said, you won’t have this flexibility if you rely solely on an FTM system. You’ll be locked into your utility company’s schedule and pricing structure. And that’s not exactly ideal given how electricity rates rise every year.

Power Reliability and Availability

This is an area where I’d say FTM systems have the advantage.

As I mentioned, FTM systems operate on a much larger scale, and they have the capacity to provide a steady flow of electricity for household use, regardless of local conditions. 

Since the grid pulls from multiple energy sources (solar farms, wind, natural gas, hydro, etc.), it can balance supply and demand more effectively.

Meanwhile, some BTM systems – like solar without battery storage – can be impacted by local conditions. 

For example, solar panels generate less power on cloudy days or in winter months. If you don’t have battery storage, you’ll eventually have to pull electricity from the grid when solar production dips.

Choose Solar as Your Behind the Meter Energy System

Home solar systems have helped countless households save hundreds of dollars each year. And with incentives like tax credits and rebates making solar more affordable, it’s no surprise that more homeowners are making the switch.

If you want to start saving sooner rather than later, have a behind-the-meter (BTM) solar system installed. We, at Avail Solar, will handle all the paperwork and legwork, so you can transition to solar hands-off and stress-free.

There’s no doubt about the benefits of solar and how it can save you hundreds on your electricity bills. Yet, I’ve heard many homeowners regret going solar – not because solar itself was a bad decision, but because they picked a solar company that overpromised and underdelivered. The good news is that you can spot a bad solar company just by asking them the right questions.  In this article, I’ll walk you through crucial questions to ask solar companies before you have your home solar system installed – questions that, being in the industry for quite some time, I can confidently say you won’t want to miss.

Questions About the Solar Company’s Track Record

If you can get a read on a solar company’s credibility, you’ll quickly see which ones keep their word and which ones will likely be a headache. I’d go as far as to say this is where your savings truly start – not just in dollars, but in avoiding costly mistakes.

What is Your Business License Number?

A business license number confirms that the company is legally registered to operate in your state. This may seem basic, but it tells you right away if they’re a real business or a fly-by-night operation.

This is also an indication that the solar company has proper insurance coverage that protects customers.

You can enter their business license number on your state’s official business registration website.  Once you input the number, you should be able to view details such as the company’s registration status, filing history, and whether they are current with required documentation.

How Long Have You Been in Business?

Experience matters, especially in the solar industry, which has had its ups and downs – a real “solar coaster,” as they say.

If they’ve been around for two to three years, that’s a good sign they’ve weathered industry changes and economic shifts. 

In addition to counting the years, I recommend you also ask the company how many systems they’ve successfully installed. This is a good baseline for gauging how reliable they are in getting the job done right.

Finally, think about warranties. A 25-year warranty means nothing if the company goes under in three years. On the other hand, a well-established business is more likely to be there when you need support down the line.

Have You Worked With My Local Utility Company?

Solar installation is more than just mounting panels on your roofs. Your solar company will also have to deal with your utility company for permits, inspections, and grid connection requirements.

If an installer has experience with your local utility, that means they’re already familiar with typical timeframes, as well as areas where issues usually arise and how to overcome them quickly. As a homeowner, you’ll have fewer unexpected delays and less hassle overall.

Questions About the Cost of Installation

Getting a solar quote gives you an idea of the overall installation cost, but treat it only as a starting point. Asking these questions below will help you see whether a company is being truly transparent or just putting on a sales pitch.

How Much Does A Solar System for My Home Cost?

A solar company should be able to justify their pricing. If they give a vague answer or push a system without explaining why, that’s a red flag.

On this note, you should also ask, why did you choose this specific system design and size for my home? Their answer should mention things like:

• Your energy consumption history
• The direction and orientation, as well as shading, of your roof
• Local weather conditions

How Much Will I Save From Installing Solar?

In relation to the previous question, a good solar company should crunch the numbers and give you a clear picture of how much you’ll potentially save – after all, saving money is the whole point of going solar.

Ask for details like:

• Your expected power bill after installing solar
• Estimated monthly savings on your electricity bill
• Payback period (how many years until your system pays for itself

I want to stress that this is a really important detail, especially if you’re planning to sell your solar home later on as buyers will want to know the savings your system can generate for them.

Am I Eligible for Solar Incentives?

Solar incentives are financial benefits designed to reduce the upfront cost of installing a solar system. They can come in the form of tax credits, state/local rebates, and net metering programs.

A reputable solar installer should be able to clearly explain which incentives apply to your location and, more importantly, guide you through the process of claiming them so you get the most financial benefit possible.

What Financing Options Do You Offer?

Some solar companies offer financing to accommodate customers who aren’t able to (or decide not to) purchase their home solar outright. 

If you come across one, consider their interest rates and fees, and see whether they’re more favorable compared to bank loans or third-party lenders.

Other companies may push arrangements like solar lease or Power Purchase Agreements (PAAs), which seem attractive given they offer no upfront costs for customers. 

However, they come with long-term downsides, one issue being that you never actually own your system. Even worse, these lock-in contracts are incredibly hard to exit. In fact, many people eventually search for ways to get out of a solar panel contract.

That said, I personally recommend buying your panels outright or financing through a loan – not leasing or a PPA.

Questions About Warranties

How Long Do the Warranties Run?

Asking about warranties helps you understand what’s covered, what’s not, and how long you can expect your solar system components to last. To give you an idea, here are typical product warranties that manufacturers offer:

• Solar panels: 20-25 years
• Inverters: Around 10 years
• Solar batteries: 10-12 years

Your solar company should walk you through their warranty policies and explain what to expect if something falls outside of the coverage period.

Are There Warranties for Solar Installation/Labor?

Aside from warranties on solar panels and inverters, you should also ask about a workmanship warranty – this covers the actual installation work. It ensures that if something goes wrong due to poor mounting, wiring, or structural errors, the company will fix it at no cost to you.

Workmanship warranties usually last within 5 to 10 years, and cover issues like roof leaks from improper mounting, loose/faulty wiring, and bracket instability, among others.

Clarifying these details with the solar company will help you understand the specifics of what’s included in the terms. As much as I’m aware, damage from hail and fire is usually covered under your home insurance policy.

Do You Cover Repairs and Maintenance?

If your system is still under warranty, repairs and maintenance are usually covered by it. Still, I recommend getting a detailed explanation of these conditions from your solar company so you’ll know exactly how servicing is handled and when extra fees might apply.

That said, ask them how you’ll go about monitoring your system’s performance. This is important as warranty repairs are usually only acknowledged if you can show proof of the issue.

And don’t forget about solar panel cleaning. Some companies include this service in their maintenance package, while others leave it up to you.

Questions About Solar Installation Work

How Long Will the Installation Take?

Asking about the installation timeline helps you prepare for any possible disruptions at home and set realistic expectations about when you can start enjoying those solar savings.

This is also the perfect time for your solar company to tell you which aspects of the process are beyond their control. 

Permit approvals from local authorities and other bureaucracies can for sure slow things down. Still, your solar company should be upfront about this and give you an estimated completion time.

Finally, ask what happens if they don’t finish on time. Will there be compensation, or do they just extend the deadline? Either way, the bottom line is that your company should have clear procedures in place for any unexpected delays.

What Products Do You Install and Why?

Here, you’re asking about the brands and manufacturers they work with, which gives you an idea of the quality and reliability of the equipment. More specifically, ask about warranty coverage, efficiency ratings, and expected lifespan.

This should also give you the opportunity to do a quick online search or get a second opinion to verify the details and avoid those cheap, low-quality products that some companies use to cut costs.

Is Your Team Trained and Certified for Installation?

As I said earlier, solar installation goes beyond just mounting panels. It also involves electrical work, roof modifications, and strict compliance with safety standards. So, it’s extremely important for technicians to have the proper qualifications to get the job done right.

NABCEP (North American Board of Certified Energy Practitioners) is a widely recognized certification that many solar companies hold. While your provider may have other certifications, NABCEP is one you should definitely look for.

Will You Handle All the Necessary Paperwork?

Your solar project will require permits, interconnection agreements, and rebate applications. 

Some solar companies include this service as part of the package. For instance, at Avail Solar, we take care of everything, from design and permitting to installation and after-sales support.

Others, however, may treat this as an extra service and, charge an additional fee for it.

Either way, make sure to ask what your role will be regarding the paperwork – or if you have any role at all – so that you know exactly what to expect.

Who Do I Contact for Concerns, Issues, Servicing?

In most cases, solar is a one-and-done setup that requires very little maintenance. But issues can still arise over time, so you’ll want to know who to call for support.

That said, a solar company should be able to point you to a specific department or person for this specific purpose. 

More importantly, ask them how fast they usually respond to service requests. If they show some hesitation or give vague answers, it could mean they’re either stretched too thin, or worse, they don’t have a dedicated support team at all.

Questions About Future Expansion

Can I Add More Solar Panels Later On?

If you manage to keep your energy consumption low in the coming years, that’s great. But in most cases, energy needs rise as you add new appliances and upgrade your lifestyle – not to mention the rising electricity rates every year.

That said, it’s a wise move to ask your solar company whether your system can accommodate future expansion.

More specifically, ask your installer:

• Can I fit more panels on my roof with the remaining space available? 
• Will my inverter be able to handle extra panels if I expand later or would I need microinverters or optimizers?
• What are my options if I need more power but have limited space?

Since you’ve already hinted at your long-term plans, a good solar company should guide you on efficient panel layouts and whether it makes sense to install an oversized inverter upfront to make expansion easier.

Can I Add a Solar Battery Later?

Even if you’re not ready to install a battery now, it’s worth asking whether your system will be battery-ready in case you want to add one later. Batteries provide backup power during outages and allow you to store excess energy for nighttime use.

Some key questions to ask:

• Will my system be compatible with batteries later?
• If I decide to add a battery, what modifications would I need?
• Considering battery lifespan, would my panels outlast the battery?

Will I Need to Replace or Repair My Roof?

Solar panels are designed to last 25+ years – but your roof might not. 

The good news is that this is something addressed during the permitting process. If your roof is older or shows signs of wear, a reputable solar company will recommend the necessary repairs or actions you must do before installing solar.

If you plan to stay in your home long-term, it’s worth asking what happens if your roof needs repairs or replacement while your solar system is still in place, and how much it will cost you to remove and reinstall your panels.

Wrapping Up on Questions for Solar Companies

I’ve shared a long list of questions you should ask before signing a contract or committing to a solar company. Of course, you don’t have to ask every single one, but the more you do, the more peace of mind you’ll have – especially since this is a long-term commitment with your solar provider.

At Avail Solar, we’re more than happy to answer these questions, whether over the phone or in person. Our goal is to give homeowners a smooth, stress-free experience while helping them enjoy the savings and benefits of going solar.
