Researching Solar Companies


Do Some Digging

Figure out whether a company values you - or just your business.

Taking the time to ask the right questions is your shield against solar scams and disappointment. A solar array has an expected lifespan of over 25 years, so this is a long-term commitment. A reputable installer will never rush you or force you to make snap decisions. So ask away!

Summary
  • Ask the right questions to get to know the company. 
  • Company background matters. Look for experience, honest (and specific) reviews, and a proven track record.
  • Red flags include companies with a history of complaints and companies that don't offer in-person site surveys.
  • Green flags include companies that physically measure your roof, explain the timeline with clear steps and dates, and handle all necessary permits and paperwork.

A company's background, experience, and reviews can tell you a lot. Finding this information online is an easy way to compare solar companies.

They’re a relatively new company with limited experience in your area or with your type of installation. Watch out for short, generic "five star" reviews that may not be authentic.  

green-flag.svgGreen flag:
They have a long-standing presence in the industry. They have positive, honest customer reviews, and a track record of successful installations. 

If a solar company has been around for a long time, with happy customers spanning decades – that’s a good sign! With experience comes strong relationships with suppliers, meaning they can get the best equipment (from inverters and solar panels to racking and wiring) at lower prices.

Years of installing leads to improved processes, smoother installations, and fewer surprises. Experienced companies are better equipped to handle complex projects and troubleshoot issues. Since solar is a long-term investment, choosing a company with a proven track record means they'll likely be around to honor warranties and provide support for years to come.  

Online reviews also say a lot about a company. 

A recent NPR article about solar fraud advises people to look for reviews mentioning specific stories or resolved issues. Some solar companies flood sites with fake 5-star reviews.
