First Response Solar did exceptional work in installing a roof solar system and backup batteries at our new home. The two brothers and company owners (Dylan and Chaz) were always polite, professional, and punctual. They handled the entire install, permitting, and PG&E approvals with ease and always maintained an orderly and safe work site.
Most importantly, their pricing was very competitive and they completed the job as promised and on schedule. If you're considering adding solar to your home, you can't do better than these guys!

There is awesome, and there's AWESOME. Dylan and Chaz - First Response Solar - besides having really cool names, install one helluva of solar system (how cool is to say you installed a solar system!?). Personally, the fam and I are always attempting to be as awesome as we can be, and First Response has only helped our property achieve a new level of awesomeness. From start to finish, the experience with First Response was top notch: from the intros, to the explanations, to the pricing, to the patient Q&A, to the install, to the support, to the communications - all of it was the expert. If you wanna be smart and awesome and make good decisions like I do, then call First Response Solar to get a quote and have them install your solar system asap - you don't even have to thank me for the great decision you've made - take the credit yourself. You're welcome. Thx Dylan and Chaz, the pleasure was ours. Tyrone

We had the pleasure to work with First Response Solar on our recent solar installation. Dylan and Chaz were excellent through the whole process. From their first visit to assess the property, to explaining options for solar placement and financing, to installation, to inspection, they were very responsive, attentive, and hands-on about what can be a very elaborate and complicated process. They have followed up several times since installation to ensure that everything was going as it should. We could not be more happy with the service that First Response provided. I recommend them without reservation.

First Response Solar has a client for life. Dylan and Chaz were phenomenal, incredibly professional, efficient, and knowledgeable. They handled this smaller inverter swap in about an hour and a half.
What really stood out was their attention to detail and care. They noticed dry rot behind the previous inverter, let me know right away, then went the extra step to prime and seal the area before installing the new unit.
It’s refreshing to see a family-run business take such pride in their work. Fast, honest, and genuinely caring service. I give them my highest recommendation!

Thank you so much for the wonderful review Tyler. We greatly appreciate the kind words and hope the new inverter last a very long time!

Serge ZimberoffLocal Guide · 17 reviewsiTotal number of Google reviews Serge has written across all businesses on Google Maps, not just this one.
First came heat pumps and an EV. Having our solar system installed was the last step in our transition to becoming an electric home with its own power source. Along the way we had plenty of time to research rooftop solar and local contractors.
First Response Solar stood out from the very beginning. It was clear that they understood why they used each piece of hardware and how these pieces related to each other and to our needs. We chose them over three other proposals and could not be happier!
In addition to doing top notch workmanship, Chaz and Dylan are easy to work with. Our system performs exactly as they had described it to us. Obviously it is a big step to invest in a solar roof and we feel that we now have a system that is well designed, perfectly installed and fully operational. We cannot recommend First Response Solar highly enough.
