Top solar myths you shouldn't fall for

At EnergySage, we hear a lot of myths about going solar.

"Solar panels are free! But they don't work in the winter! And they damage your roof!" (No, they're not. Yes, they do. And no, they don't.)

Here are some of the top ones most in need of busting.

You may come across scammy solar advertisements about "free solar panels from the government." This isn't true. While you can go solar for $0 down with a solar loan or lease, federal and state governments do not provide free solar panel installations.

While the government won't cover the cost of a solar panel installation, they do subsidize the upfront cost of purchasing a solar panel system through various solar incentives. For example, the federal investment tax credit (ITC) allows you to claim 30 percent of the cost of your solar installation as a credit toward what you owe in federal taxes. Depending on where you live, your state or local government may also provide additional solar incentives such as tax credits, rebates, or performance-based incentives (PBIs).

Many people are under the assumption that solar panels are a luxury purchase and strictly an option for affluent people. This is no longer true: Thanks to the falling costs of solar and the accessibility of financing options, solar is a feasible option for many property owners.

The cost of solar has dropped substantially in the last decade. In 2008, the average cost of a solar panel installation was $8.82 per watt. As of October 2024, the average cost for solar quoted on EnergySage now is $2.75 per watt.

As far as financing options go, solar loans and leases are available for no money down. In many cases, the monthly loan payment is less than the monthly pre-solar power bill. If your solar system covers 100% of your power needs, you'll see savings right off the bat.

It is possible to install an off-grid solar panel system using solar batteries, but most solar panel installations are grid-tied. This allows you to use solar energy your system produces during the day and draw electricity from the grid after the sun is down.

That doesn't mean you can't cover all your electricity needs with a solar panel system. Through a policy called net metering, your utility will provide credits on your electricity bill for excess energy produced during the day.

If you generate more electricity than you use in a given month, you can use those net metering credits to offset a future bill.

Net metering policies can vary by state and utility, so it's a good idea to check with your utility company about the specifics of their net metering prior to going solar.

Yes, solar panels need sunshine to generate electricity. And, yes, solar panels covered in snow can't generate much power. And yes, northern states experience fewer hours of daylight in the winter than their southern friends.

But that doesn't mean solar panels don't work in the winter. Far from it. In fact, while the sun is shining during the winter months, solar panels actually perform more efficiently due to the colder temperatures.

Despite the snowstorms and shorter days, solar panels will still generate enough power in the winter to provide savings on your electricity bill. And if your panels do get covered in snow, they won't be for long. The smooth surface and angled orientation means any accumulated snow typically slides off once the sun comes out.

This isn't true, except in rare circumstances.

Most utility companies have restrictions to prevent you from interconnecting a solar panel system that produces far more energy than your meter history indicates you need. Even if you are generating more solar energy than you're using, utilities that offer net metering will provide monetary credits towards your future electricity bill, but rarely will they pay these out as a check - more likely, it will remain an ongoing credit on your electricity bill.

In the rare circumstance that your utility company does send you a check for excess electricity, it's likely for a wholesale electricity rate with a much lower value than a net metering credit.

Another circumstance in which you'd receive a check from your utility for solar energy is if they offer a PBI for solar generation separately from net metering (for example, National Grid's Renewable Energy Growth incentive).

Some property owners hesitate to install solar on rooftops because they worry about possible damage. Luckily, roof damage from a solar panel installation is extremely rare.

For one, solar installation companies will inspect roofs before installing. An engineering and structural review of your roof will confirm whether or not it can withstand the added weight of a solar installation.

And while most solar installations require holes in the roof to affix the racking, good installers apply sealants in these holes to prevent roof leaks.

Solar installers will also provide a workmanship warranty (typically 5 to 25 years) to protect you on the off chance that damage occurs due to their installation work.

As long as you work with a qualified, licensed solar professional, you shouldn't have to worry about roof damage. Stories of roof damage after solar installations are usually a result of a poor installation or a company installing solar on a roof that wasn't in good condition to begin with.
