Day One Solar reviews

Daniel O. had Day One Solar put a home battery backup unit on his ranch-style house a few years ago and later upgraded it when a better system became available. He found the company consistently reasonably priced, responsive, and easy to deal with. Megan, Matt and Ray guided him through both the original install and the upgrade, patiently answering questions whenever he had them. The detail that stands out is the ongoing support and clear upgrade path — he still turns to the same team for answers, which is what stuck with him.

Bruce B. discovered in August 2023 that his nearly four-year-old rooftop solar system — which had been flawless until then — started tripping the main panel breaker. He contacted Megan at Day One Solar, and she sent a technician out immediately; what followed was several rounds of troubleshooting as the team worked persistently to isolate a stubborn electrical fault. After testing and elimination of other causes, the crew made the ultimately correct call to pull new wire from the main panel to the inverter, and that replacement stopped the breaker from tripping. The install team had originally won the job four years earlier with the low bid, but they didn’t treat the system like someone else’s problem: they returned promptly, stayed professional and pleasant on site, and stood behind both the equipment and their workmanship. The detail that sticks — a low-bid installer coming back years later, digging into a difficult diagnosis and fixing it by replacing the panel-to-inverter wiring — is what he remembers most.

Sigrid B. has worked with Tony and his Day One crew twice — once on a nonprofit project in 2017 and more recently on her own roof in Aptos. She helped support the nonprofit effort, where Day One delivered a fairly complex 66 kW system that combined ground mounts and roof panels. They completed that job at a competitive price, and more than two years later the system is still running smoothly and the nonprofit is seeing real savings on its bills. For her house, Day One installed a 6.5 kW rooftop array. From first contact to finished installation took under three months overall (even with summer travel and vacations causing delays), and it only took about one month from the time she signed the contract to having the panels up. The crew worked in a friendly, efficient, professional manner, and the pricing again felt very attractive. What stood out was the team’s range: the same crew handled a complicated commercial-scale ground-and-roof 66 kW project and then turned around a tidy 6.5 kW residential install quickly — both at attractive prices and with systems that performed as expected.

Renee bought a solar system for her home about eight years ago. Every stage — from the initial installation through years of maintenance — proved professional, prompt and excellent. When a few issues cropped up over the last two years, Day One Solar responded quickly and resolved them efficiently. Megan stood out, offering knowledgeable, helpful and timely support. What stuck with her was that responsive, expert follow-through — concrete proof the company stands behind its work.

John Sera's solar inverter died in 2020, right in the thick of the Covid crisis, and he ended up losing about six months of generation. The original installer had been bought out and stopped providing service, and Day One was the only company he could actually reach. Day One stepped in, treated him with straightforward courtesy, and arranged a replacement inverter promptly—turning what had been a long outage into a quick, painless repair. What stuck with him was how easy the whole interaction felt: polite people, clear communication, and a fast solution when other options had vanished.

When Terri Kalia discovered a problem with solar panels another company had installed, she reached out to Day One Solar to diagnose and repair the issue. They inspected the system, drew up a repair quote and timeline, and arrived on schedule. The team worked through the job while keeping her informed—explaining progress, flagging any difficulties, and describing how they resolved each problem. Their punctuality, technical skill and customer-focused approach stood out. She ended up with the system fixed and enough confidence in their communication that she will hire them again when needed.

John Carothers discovered one of his solar panels had stopped working and reached out to a company that hadn't installed his system. They showed up promptly, traced the problem down efficiently, and repaired the faulty panel — their technical know-how and quick response made the whole fix straightforward. He appreciated that they were willing to service another installer’s equipment and plans to call them back when he expands the array.

Bill brought Day One in to add a home battery to complement the solar panels already on his roof. He ended up with a neat, professional installation: Ray and the rest of the technicians showed up on time every day and worked efficiently, and Shaman handled parts of the install cleanly as well. When the SGIP refund got held up in PGE bureaucracy, Megan dug in and relentlessly pushed on his behalf until the payment finally came through. The detail that stuck with him was not just the punctual, professional crew but Megan’s persistence in getting the refund released.

Ty chose Day One Solar to install a combined solar and battery system on his home and deliberately waited several months after the crew left to judge how the company would handle follow-up. He discovered they stayed engaged — checking back, making sure everything was working, and addressing any concerns. The installers arrived professional, left a neat, well-executed array on the roof, and the workmanship looked attractive and tidy. When questions did come up, Megan repeatedly tracked down clear answers and kept communication moving. More than the spotless installation, what stuck with him was the consistent post-install attention and the dependable point of contact.
