10 Best Solar Companies

Which solar company should you choose? Here are our top picks.

Just a few decades ago, solar panel companies were still trying to get a strong foothold in the American economy as a valid source of clean, affordable energy. And in those early days, let’s be honest: solar panels weren’t all that affordable for the average homeowner. However, today’s best solar companies offer top-notch products at a much more reasonable price, and with tax incentives and rebates, installing solar panels on your home is a quite feasible option. 

Over time, the best solar companies have created a quasi-monopoly, with smaller brands being acquired by the larger brands. However, it’s important to remember that these companies are merging because they offer the same or similar products, good customer service, and the same sort of installation techniques. They are also merging to cover more states and deliver different types of panels. When you search for one particular company online, don’t be surprised if another pops up thanks to those acquisitions – for instance, Third Sun Solar LLC was recently acquired by Kokosing International, while CleanCapital made a recent purchase of BQ Energy.

Top Solar Companies

The best solar panel companies are at the top of their game for a reason: they offer affordable prices, flexible financing options, complete their projects on time, offer excellent customer service before, during, and after the installation, and offer solar panel construction warrantied to last for decades. There are also some companies that will help you take advantage of local, state, and federal benefits for solar panel installation. We looked at these points and a variety of others to come up with this top 10 list of the best solar panel companies.

Frequently Asked Questions

Should I get fixed or tracking solar panels?

For those who have a smaller home and good sun exposure, fixed panels can easily provide enough power. Tracking solar panels tend to be reserved for very large homes or commercial businesses, mostly because they cost so much in up-front costs, need a great deal more maintenance than fixed panels, and might not provide enough energy to create a good return on investment.

How do I know if my home is a good candidate for solar?

Many factors go into answering this question, including where you live, how much sunlight you get each day (on average), the shape your current roof is in, what kind of rebates or incentives you might get, and whether a particular company operates in your area. This handy tool from Project Sunroof can help you determine whether it’s worth pursuing solar panels.

How many solar panels does an average home need?

If you want to cover 100% of your energy usage through panels, expect to need 20 to 25 solar panels. However, how many you actually need depends upon your sun exposure, the type of panels you install, and how much energy your household uses. (This is based on a 2,000 square foot home.)

What should I expect to pay for solar panels and installation?

There is no easy answer to this question, for the cost can vary widely depending upon the number of panels and the cost of installation in your area. The average cost of solar panels and installation works out to a national average of $25,633. Keep in mind that this number doesn’t include tax incentives or rebates that can drop the cost dramatically in some areas. Our solar panel calculator can help you figure out what you might pay for solar in your area.

Do solar panels work in snow? Do solar panels work in shade?

Yes, the panels still work, but the amount of energy they collect will vary depending upon the time of year, the angle of the sun, and how much shade or snow is covering the panels at any given time. When the sun can’t hit the panels directly, expect for that panel to fall short of its potential.

Can solar panels withstand extreme weather like hurricanes?

Solar panels can often withstand extreme weather such as hurricanes, hail, and a deluge of driving rain. However, they can be damaged if the weather is severe enough. And if the power grid goes down in the aftermath of a storm, the solar panels will go down too (though your battery backup can help extend the time you’ll still have power).

How can I find a reliable solar installer?

Modernize can help! We offer the opportunity to connect with local contractors and solar installers in your area who can explain everything from how financing works and your potential return on investment to the actual process of assessment and installation. Let Modernize do the heavy lifting in getting you in touch with the professionals who can make it happen, and you can start planning out your solar panel installation.
