O3 Home Solar reviews

Odis installed a residential solar system two years ago and found the panels still performing reliably with no surprises. He appreciated that the sales team never leaned on him, the installers were courteous, and the company handled financing in a way that fit his budget. A couple of months after installation a wiring problem surfaced; the crew spotted it, reached out, and came back to fix it promptly — the kind of proactive follow-up that stuck with him. Overall, he walked away with dependable equipment and a quick-service response when something went wrong, and the early repair is what he remembers most.

Darrin had solar panels installed by another local company but ran into a persistent power problem they couldn't resolve. He reached out to Bruce at the new team, who scheduled an appointment quickly; the crew diagnosed and fixed the issue that the original installer left unresolved. Beyond the repair, Bruce walked him through exactly how the system works, answering questions and demystifying the setup. He appreciated the hands-on customer service and left a five-star review — what stuck with him most was that the visit was both a fix and a clear, practical lesson in how his system operates.

Chris Gray went solar with O3 in 2019 and quickly discovered the company’s underproduction guarantee would become the main story of his ownership. The policy promises to refund the shortfall if a system underperforms, and in 2022 his array delivered about $900 less than expected. He spent eight months chasing that refund — logging 38 emails and several phone calls — and found the CEO either unresponsive or unwilling to honor the payment. That followed a similar ordeal in 2021, when it took nine months, roughly 40 emails and multiple calls to secure a separate refund. He also noticed a review he posted the previous year disappeared from the site and points to a trail of complaints on the BBB as context for the pattern. After repeated years of underproduction and long, frustrating back-and-forths, he won’t use O3 again; the concrete detail that stuck with him is the sheer volume of correspondence required to try to enforce a guarantee for only a few hundred dollars.

Ben had 71 solar panels installed on his roof about two years ago and the array worked flawlessly. In May 2022 he agreed to add a battery backup and, as with the original job, paid a 50% deposit up front so the company could order the equipment. After a year of waiting he couldn’t get anyone with authority to explain why the battery wasn’t installed, and he ended up out of pocket with no resolution. He concluded the company had become dishonest in how it handled the follow‑up. His concrete takeaway for buyers: don’t pay a deposit unless it can be held in escrow with specific performance conditions.

Brian Martinez rarely writes reviews, so when he did he wanted to highlight how pleasant the whole experience was. He enjoyed interacting with every person from the company and felt the team's customer service made the process smooth. He left fully satisfied with the work and says he would choose them again in a heartbeat if he needed additional solar services. The detail that stuck with him most was the consistently friendly, professional people he dealt with.

Anita T hired the company to install a 49-panel solar array on her home back in 2000 and discovered the system never worked right. She found roughly half the panels sitting in shade and learned the crew didn’t even switch the system on for more than a year during the COVID period. The installer kept asking her to be patient and promising to handle it, but when the system was finally activated it still underperformed. The company then tried to claim the system was out of warranty; she produced her contract proving a ten-year warranty, yet reimbursement for the poor performance never arrived. Even after copying the company president on her emails, she received no response. After more than two decades the panels remain nonfunctional and the promised fixes, payments, and leadership engagement never materialized—what sticks is that she had to prove the warranty herself and still hasn’t been made whole.

Gregory encountered a consistently pleasant team throughout his solar project and enjoyed working with every person he dealt with. He ended up deciding he would hire them again if he ever needs additional solar work, because the uniform professionalism and friendliness across the staff made the choice easy.

Nathan S. bought a rooftop solar system in March 2021; installation didn’t even begin for nearly seven months. When the array finally went live, it carried a production guarantee of 18,000 kWh per year — but over the next two and a half years it produced only about 9,000 kWh in total. He spent more than a year and a half trying to get O3 Home Solar to fix the shortfall. For a few months the company messaged that they were trying to resolve the problem but offered no concrete timeline or solution, then they stopped returning calls and emails for over a year. A few months ago they directed all communication to their lawyer, who insisted arbitration was the only contractual remedy. He discovered arbitration can run roughly $500 an hour and commonly reach $3,000–$5,000 per day, with him liable for half those costs. The company refused to repair the system or honor the production guarantee; several friends of his report similar underperformance. Now he continues paying his full electric bills while shouldering about $200 a month for a system that has produced roughly half the promised energy.

After buying a house already fitted with an O3 solar system, David O'Brien gathered the previous owner’s paperwork and tried to get the installer to honor the warranty. He pulled an earlier complaint after O3 Energy Solution replied that a sister company handled residential work, then later discovered that O3 Home Solar is permanently closed. Inspecting the equipment, he found the main breaker the installers used wasn’t rated for the panel — a clear fire hazard — and every attempt to reach the company went unanswered, so he couldn’t get the dangerous wiring corrected. His takeaway: a listed warranty is meaningless if the company won’t return calls, and anyone with one of their installs needs a licensed electrician to double‑check the panel and breaker right away.
