Every purchase of Tesla solar panels or roofs includes a Tesla Powerwall, which offers 24/7 energy storage to meet your electricity demands during outages.

Other companies we considered

While the brands above made our list of the best solar companies, we reviewed many other solar panel manufacturers and installers. Here are a few of the companies that we considered during our research.

  • American Solar. American Solar services 16 states and provides 25-year product warranties in most of them. The company also offers solar loans, leases and zero-down financing options. Once you book a consultation, its representatives will visit your home to provide a personalized quote based on your electricity usage, roof and energy goals. However, American Solar's website provides little information and no pricing details, and the company doesn't have an in-house installation team.
  • Solar Energy World. Solar Energy World is a regional installer based in Maryland. It installs solar panels and batteries from multiple manufacturers. Nevertheless, the company services only eight states and D.C., making it an option for fewer customers.
  • Smartflower Solar. Smartflower's innovative design is shaped like a flower and installed on the ground instead of the roof. Like other runners-up, Smartflower provides very little information on its website, so it's hard to evaluate its offering.
  • Sunlux Solar. Sunlux is a Tesla-certified installer that operates in California and Texas. It also offers smart home packages to have better control and insights into your electricity usage. Its limited service area disqualified it from our top picks.

Solar Companies Guide

The following guide covers important information about solar companies, including how to choose the right solar provider and the average solar installation cost.

Main things to know when choosing a solar company

If you're ready to go solar, consider the following factors when comparing solar companies:

  • Service area: As you can see from this list, very few solar panel companies service all 50 states. While there are many options on the market, look for providers that service your area and have a local branch with good customer service ratings.
  • Financing options: Most solar companies offer several different financing options. Read about and understand each option to determine which is best for your situation. While lease and Power Purchase Agreements (PPAs) have fewer upfront costs, you don't own the equipment.
  • Type of solar equipment used: Many companies offer equipment from various solar panel manufacturers. Some will mix and match panels and inverters based on their workers' skillset or simply to save money. Research which panels are best for your local weather and the type of roof on your home, then narrow down your options to companies that offer the panels you want.
  • Warranty and maintenance: Solar panels are a long-term investment. With an estimated lifespan of 20 years or more, you'll likely have maintenance or warranty claims at some point. Make sure the solar company you're considering has a good reputation and will stand behind its products.
  • Battery storage options: For homeowners that want to store excess energy or be able to operate "off-grid," does the company offer battery storage? If so, what are those costs, financing options, and warranty coverage?

What is the average cost of solar companies?

The average solar panel installation costs around $20,000, including equipment and labor. However, installation fees vary by company. Factors such as the financing option you choose and the number of panels and additional equipment you order will also affect the final price. You should also factor in the federal tax credit (now 30%) and any other rebates and incentives, which could considerably lower the cost of installing a solar photovoltaic (PV) system.

Another potential expense to consider is your homeowners insurance premium. According to Nationwide, a standard homeowners policy should cover a rooftop solar system. Still, you may have to increase your coverage (which will increase your premium) depending on the cost of the equipment. Read our guide to the best homeowners insurance carriers for more information on homeowners insurance and what it covers.

How can you find solar companies in your area?

Finding a solar panel company that services your area could entail a bit of legwork. Start by talking to friends and neighbors that already have solar and can give you some recommendations. If you don't know anyone with a solar energy system, online review sites like Yelp! and TrustPilot can be good resources.

You could also check with your local permit office to see which companies have recently installed systems in your area. Lastly, most options on our list of the best solar companies allow homeowners to input their zip code or address on their website to determine if service is available in their area.

How do you know if a solar company is legit?

At first glance, it may be hard to tell if a solar company is legit or fake. You can filter out scammers by seeking referrals from existing customers, checking permit records at your county office and reading online reviews.

People who have been scammed or treated poorly usually share their stories with anyone who will listen. Websites like the Better Business Bureau (BBB) keep track of consumer complaints and ratings, and these can help future customers avoid potential fraud.

How to avoid solar energy scams?

Unfortunately, some scammers target homeowners trying to save money on utility bills. To avoid getting caught in one of these scams, consider the following.

  1. Don't give out private information. Never disclose your Social Security number, and only provide your financial information once you're ready to buy. You shouldn't have to provide these details to see if you qualify for solar.
  2. Don't fall for high-pressure sales tactics. Scammers often rush victims to make quick decisions. They'll say it's a limited-time offer to try to close the sale before you can research the company or verify the scammer's claims.
  3. Don't pay upfront. A solar company may ask for a deposit before installing solar panels, but you shouldn't have to pay the total cost of a system upfront, especially not to obtain a quote.
  4. Get multiple quotes. As with any home improvement project, it's wise to get at least three quotes from reputable companies. This will help you compare prices and understand your options.
  5. Research the companies you're considering. The internet makes it easier than ever to research companies and contractors. Read customer reviews on consumer rating sites like the Better Business Bureau (BBB), Yelp, Google and Trustpilot. Your local state contractor licensing board may also be able to provide you with details such as a company's current license, number of years in business and customer complaints. To learn more about licensing requirements by state, visit the Interstate Renewable Energy Council's (IREC) website.
  6. Ask questions. Investing in solar is a big commitment. You should feel comfortable asking as many questions as you need to make a decision. If a company fails to answer your questions or provides contradictory information, take it as a red flag.

Solar companies FAQs

Does home insurance cover solar panels?

chevron-down
chevron-up
Solar power installations permanently attached to your roof are generally covered under your dwelling coverage. If a covered peril damages your solar system, your homeowners insurance coverage may pay to repair or replace it. After installation, contact your insurance agent about updating your policy limits to ensure your system is fully covered.

Do solar companies need your electric bill?

chevron-down
chevron-up
Yes, the best solar companies use your electric bill to determine your average monthly energy usage. The company can customize a solar panel installation that meets your needs if you can provide a year's worth of electric bills.

How much energy can you reduce using solar panels?

chevron-down
chevron-up
A typical homeowner that installs solar panels can reduce their electricity usage by up to 90%. Nevertheless, monthly usage will vary by household and the power the solar system generates.
