My wife and I purchased a new 19 panel solar system and Tesla Powerwall in mid 2025. The install…read morewas completed in October 2025. The crew and all of the people at United solar Electric were very responsive and professional. I would, and will do business with them again, (adding an additional battery). PG&E was a problem. PG&E was very slow with providing PTO (permission To Operate). We did not receive PTO until end of May 2026, over 6 months from the date when system was operational. PG&E will need to upgrade transformer (December ???) before we can send greater that 2000 watts back to the system. Right now, we have conditional permission to operate, limiting output to PG&E to 2.2 KW. To United Solar Electric's credit, they were with us the entire time dealing with PG&E and were just as irate with PG&E as we were. Thank you, United Solar Electric!

My wife and I had a very concerning experience with United Solar Electric regarding their business…read moreethics and refund policies. We were interested in solar for our 1940s home and provided a deposit in good faith. However, after further inspection of our roof and the overall project viability, we decided not to move forward. When we requested our deposit back--before any equipment was ordered or installation began--the company initially refused, claiming it was 'passed' the point of a refund. It was a high-pressure situation where we felt they were trying to lock us into a contract we weren't comfortable with. While we did eventually receive our deposit back after pushing the issue, the initial refusal to return funds for work not performed was a major red flag. Homeowners should be very careful with the fine print here. If you are looking for a company that values transparency and customer comfort over just 'closing the deal,' I would suggest looking elsewhere. We're glad we didn't get stuck with them and are instead putting that money into improvements that actually fit our home.

Robert C. came to my home and went over the advantages of adding a few more panels that would still keep me in tier 1 status with the power company as well as consideration of adding a Powerwall III battery. Considering the increased power generating capacity of newer panels and storage capability of the Tesla battery, I was sold by the quality and value of the expanded system. The design and contract review was done online in a timely fashion and it was a swift transition to installation taking place in just one day, as the the lead installer (Antonio) was joined with two co-workers who explained how the project would move forward and answered all my questions. The work was complete by 3pm and I was extremely satisfied with the entire process. Thank you Semper Solaris for a quality job for a fellow veteran. Dan

Semper was very professional and gave us a reasonable price and guidance for tax credits at that time.

Ken from Semper Solaris came over and we considered all the options and we received some credits for our loyalty.

The entire team has been very professional and clean up afterwards everyday they've worked. Love the new roof and gutters!

Synergy owner Eric Piekarczyk recently demonstrated proactive ethics that are hard to find. The…read morecompany failed to assist in diagnosing a component known as a Gateway in my pv system. Which resulted in prolonged failed solar generation. Eric, rather than blaming the problem on anything or on me offered 2 extra panels in compensation. This says that the company like all of us is imperfect and that the owner has a high ethical bar. In a time when our country is being governed corruptly something like Eric's behavior shines. That's my Synergy story. Richard Kamp
