Positive reviews:
“Day One Solar installed our home battery back-up unit a few years ago and then we upgraded it when a better solution became available. They are unfailingly reasonably priced, responsive and easy to deal with. Megan, Matt and Ray have been able patiently to answer questions whenever I’ve had them. I’d recommend Day One Solar to anybody!” – Daniel O. ⭐⭐⭐⭐⭐ December 18, 2024
“An update for this company is warranted after another outstanding experience. In August 2023, our solar system began tripping the breaker in our main panel after nearly four years of flawless performance. I contacted Megan. She sent a representative out immediately to troubleshoot the problem which proved more difficult than thought. The Day One Solar team worked persistently to identify the problem, finally making the ultimately correct decision to pull new wire from the main panel to the inverter, which solved the issue.The entire Day One Solar team was dedicated to resolving this problem, which they ultimately did. And this, after four years since our initial installation, which, by the way, they won with the low bid. Not only are these highly competent professionals, they are a pleasure to have on the job as well. They stand behind their product and workmanship. Everyone knows that’s worth everything in today’s world. Well done.” – Bruce B. ⭐⭐⭐⭐⭐ October 20, 2023
Positive reviews:
“Day one bailed us out big time. Our inverter died during the height of Covid and we lost 6 months of generation since well… in 2020 there were plenty of other things to worry about. Anyway the company who installed it had been bought out and wasn’t providing service anymore, and day one was the only one we could reach. They were so nice, got us a new inverter promptly, so easy to deal with. Just all around great people.” – John Sera ⭐⭐⭐⭐⭐ September 2025
“These guys did an awesome job on my project. There were lots of unusual things with my install, and they breezed through it quickly and professionally. 16kW DC / 12kW AC ground mount in Bonny Doon.” – Scott MacAfee ⭐⭐⭐⭐⭐ 2025
