I wanted a system that…
I wanted a system that had enough power production to cover running all household appliances at once plus a hot tub, and still have leftover power to send back to the grid. I also asked for expansion capability for electric car and batteries down the road. I got everything I wanted for a price that was under what I'd expected it to cost.

Installed a system for us…
Installed a system for us in Oct 2021. Perfect job from start to finish -- system design was for a difficult roof, but worked out great and is producing slightly more than predicted. Cost and schedule was more than competitive. Permitting process and acceptance by PG&E was smoother and faster than expected. Install crew and office support very professional. We couldn't be happier with the project.

Great experience, they use the highest quality products on the market, installation was fast and painless, and cost is much less than the big guys in the area. The owner, customer service rep, and field team are great! If you are comparing as I did, choose Day ONE!

They did a great job…
They did a great job of installing our solar panels and battery. The battery did give them a hard time but they kept after it until it worked. We have not paid PGE for electricity for 9 months. We run completely off the solar panels and battery.
