SunPower Reviews

“When I opened my SunPower app on Sunday it showed nothing. I hit the help key, called the number and [a representative] answered. After making sure I was the account holder, she was able to tell me that I lost connection to my wireless the night before. She then took me step-by-step to reset [my system]. It was fast, easy and worked. Great customer service at all times.” —Steven G. via the BBB

“Before I got this company, I did a lot of research on other companies and found SunPower to be straightforward and professional. It gave a timeline of when to expect things. The installation was done in a couple of days. [SunPower] left my house clean when done and still followed up to make sure things were working well. This company has been around for over 30 years and is very reputable.” —Margaret L. via BBB

“Solar panels have been inoperable since June 15, 2023, and a work order was placed for correction on the 21st. Multiple attempts have been made to address the issue with the company’s service department. Three times I have been told I would be contacted within three to five business days for warranty repair work … still have not been contacted. [My] bills are soaring — the last two have been $500+ due to [my] panels being inoperable.” —Anonymous complaint via the BBB

Tesla Solar Reviews

The Tesla Energy division has limited reviews on its BBB profile. The company as a whole has an unfavorable score of 1 out of 5 stars based on over 300 reviews, but many negative reviews relate to issues with EV deliveries and customer service.

“I met with over a dozen companies before deciding to ‘bite the bullet’ and go with Tesla Solar. Oh my goodness, did I make the right choice! To begin with, its presentation was unlike any other company I interviewed — it really impressed me, and the interactive approach was A+! I’m overjoyed to have gorgeous black solar panels on my roof! The solar panel installation was painless, and the installation crew was extremely friendly and professional!” —Vance A. via the BBB

“When the presentation was done remotely, I was skeptical at first, but the solar designing technology Tesla Solar Energy quickly dispelled that concern. The presentation was outstandingly professional. The installation was quick, and my system is already producing as expected.” —Landon via the BBB

“An absolutely terrible company to deal with. Due to a problem with the equipment, [Tesla] shut down the system for two months. [Tesla] still billed us (an estimated usage) for the time the system was shut off. I called customer service to ask when the system would be repaired and they didn’t know. The customer service is one of the worst I’ve ever dealt with. I wish I worked with another company.” —Lee J. via the BBB
