Excellent service, very responsive. I've used Semper Solaris in two previous instances for the installation and follow-on installation of my Solar System and now SCE pays me for my contribution to their Grid....!

So I got Sunrun for my home install like three months ago. I just had it checked about a month and a half ago and told me everything was running perfect. I should not be getting a bill from PG&E because I have solar and I have Tesla batteries as well so the only bill I should be getting is from Sun Run, which is a set quote per month. I just got out $750 bill from PG&E because I’m using their power when I shouldn’t be using their power at all, but the solar panels are under performance. Now I’m paying almost double in electricity because I’m paying Sunrun and paying PG&E . I tried to file a claim for compensation, and I was told I could only do that once every two years, But this is a brand new system, and I should not have to use this option because of the carelessness. I told him I was going to start recording that call because I will get a lawyer and once I told him I was recording the car. They said they do not appreciate me recording and hanged up the call. STAY AWAY FROM THIS COMPANY. IF THEY MAKE THIS RIGHT? I WILL CHANGE MY REVIEW AND KEEP IT UPDATED.

I had the pleasure of working with Brian J. on April 16th in Bakersfield for an A/C service, and I couldn’t be more impressed. What started as a routine service led to the installation of a hard start kit and a secondary motor control — and Brian took the time to walk me through every detail. He didn’t just fix the issue — he educated me. Brian showed me the diagnostic readings, explained the tolerances, and clearly communicated the strain my system was under and what would likely happen if the issue was left unaddressed. His thorough explanation helped me feel confident in the decisions being made. Even better, he shared practical tips on how I could extend the life of my A/C system going forward. It’s rare to find someone who’s not only skilled but also passionate about helping the customer understand their own system. Brian’s professionalism, expertise, and willingness to go the extra mile made a lasting impression. I’m extremely satisfied with his service and would recommend him without hesitation. He’s a real asset to your team — the kind of technician who deserves recognition.
