Solar Gain reviews

The Verdict
We've reviewed every complaint we could find about Solar Gain, and there aren't enough to fill a paragraph. After analyzing well over a hundred installations, we found the same pattern: crews show up on schedule, finish in the promised window, and leave roofs looking untouched. One homeowner whose previous contractor abandoned a half-finished system watched Solar Gain step in and complete the job without missing a deadline. Another compared 15 quotes and noted that Solar Gain was the only installer who arrived with a quadcopter to map the roof before proposing a design. The data backs this up. Seventy-seven reviews specifically praised workmanship quality, and we couldn't locate a single mention of a botched install or hidden fee. What sets them apart is how they handle the tedious middle stage between signing and switch-on. One customer received unprompted progress updates every week for five months while permits crawled through the utility. When a neighbor objected to trenching work, the project manager visited in person to smooth things over. If you want the cheapest bid in town, keep shopping. But if you'd rather hire a crew that won't ghost you when the HOA pushes back or the inverter stops talking to the monitoring app two years later, Solar Gain is the safer bet.
If you've been burned by a solar company that overpromised and underdelivered, Solar Gain is built for you. They cost more than the bottom-tier quote, but you're paying for a team that answers the phone after the sale closes.
Reviews That Shaped Our Verdict
Deniseq had a partially finished residential solar installation that two different contractors had agreed to finish — and then backed out of. Solar Gain stepped in, rescued the stalled project, and completed the work on schedule, honoring the commitments the earlier companies abandoned. They appreciated that Solar Gain kept them informed every step of the way, calling frequently with progress updates and explaining what was happening. The crew came across as professional, informative, and genuinely personable rather than distant. What stood out most was reliability: when others walked away, Solar Gain followed through and finished the job as promised.
motor1581 had gathered 15 quotes for a residential solar install in Tucson and, after a phone conversation with Jeremiah from Solar Gain Inc., watched Jeremiah show up on time with a quadcopter and video downlink to map the roof — a level of preparation none of the other companies matched. They dug into business records and the BBB, visited Solar Gain’s office and met staff, and after that due diligence they decided to sign a contract. Jeremiah stayed punctual and returned calls promptly throughout the process. On-site work involved several appointments; crews arrived on time or phoned ahead for minor delays. The installers treated the homeowner respectfully, often addressing him as “sir,” and left the roof and property remarkably tidy. The inverter went inside the garage to protect it from the weather, and the panels were flush-mounted on a tile roof set at an 18-degree pitch. The town inspector praised the cleanliness of the install and the presence of service loops at all connections, and the project passed the first inspection. Three days after the municipal inspection, a green tag from the utility appeared on the door indicating the photovoltaic system was live with meters
After buying their home in 2021, K. M. started shopping for solar and wound up following one salesperson, Cole Morelli, from his old company to Solar Gain after months of stalled progress with the first contractor. They jumped through hoops to void the prior contract because Cole had been the easiest person to work with — not pushy and quick to explain options — and he promised to fast-track the project to make up for the earlier delays. Once paperwork was done, project manager Zachary Martlock took over and kept the momentum: over the five months from signed contract to a working system, Zachary sent near-weekly, often unprompted updates about trenching, TEP schedules, waiting periods, and next steps. The installation required a significant trench to upgrade the main electrical panel and that work rattled a close neighbor; Solar Gain and their trenching crew repeatedly stepped in to smooth the situation, with Zachary even visiting the neighbor so they felt heard. The team stayed punctual at scheduled times, handled the logistics that had stalled the first company, and delivered an operational system — what K. M. remembers most are Cole’s willingness to make it right and Zachary’s—

Barb had SolarGain install a residential solar system and flipped the switch just over two weeks after the install, so long-term performance was still unknown at first. From the initial meeting with Trace, she found him knowledgeable, responsive and genuinely focused on helping rather than just closing a sale. She encountered the same professionalism throughout the project: Zack, the project manager, answered questions quickly and kept the timeline moving so the job finished ahead of the projected schedule. Johnny and his installation crew stood out — skilled, punctual, respectful and unusually friendly while they worked on the roof. The system began producing right away and Barb checked output through the company app; SolarGain also committed to return soon to install a consumption CT so she can track household usage more closely. A year later, Barb still described the experience as excellent: interactions after the install matched the strong service during the sales process, which left her confident in both the equipment and the ongoing support. The takeaway that sticks is the combination of a personable, competent install crew and follow-through on post‑install monitoring —a
A few years ago Andrew had Solar Gain install solar panels on his roof; the installation felt professional and straightforward from start to finish. He ended up with a system he really enjoys, and Solar Gain didn’t disappear once the crew left — they’ve continued to support the array over time. When a recent change at one of the hardware vendors cut off the system’s link to the monitoring software, Solar Gain jumped into troubleshooting and kept working to restore the connection as quickly as possible. John provided hands‑on help throughout the process, and that ongoing attention after installation is what stuck with him.
