We found too many red flags to recommend 1 Solar Solution. Three customers paid deposits and then couldn't get the company to finish the work or even return calls. Others have watched their panels sit broken for months while service requests vanished into a black hole staffed by third-party message takers with no ticket system. One homeowner waited seven months for a replacement inverter after multiple techs diagnosed the problem, then got ghosted by the support rep named in several complaints. Another called weekly for updates and received three responses in half a year, none of them useful. The company did earn praise for smooth installations three to eight years ago, and 29 reviews mention responsive project management back then. But recent patterns show a collapse in post-install accountability. Several reviewers note the irony: the owner once told customers to choose an installer you'll trust for 25 years, yet the same company now routes service calls to outsourced reps who can't create tickets or schedule repairs.
If you're weighing quotes, cross this one off. The gap between how they treat prospects and how they treat existing customers is too wide to gamble on, and you'll be an existing customer a lot longer than a prospect.
Indrajit Gandhi has been with 1 Solar Solution for nearly eight years. For the first five years he experienced satisfactory service, but recently he discovered a sharp decline in how post‑installation problems get handled. Service calls started getting routed to a third‑party representative who simply relays messages without opening a service ticket or issuing a reference number, and the company’s internal support stopped following up directly. He hit a wall trying to resolve even basic issues: calls go unanswered, technicians promise dates and don’t show up, and communication breaks down. On August 21 the company took the full advance for a reinstallation but has not kept the commitment; it’s been two months and the panels still haven’t been reinstalled. After escalating, he received a helpful call from Ali Samana who addressed his immediate concern, and he’s waiting for further updates once the service is completed. The detail that sticks: an advance payment taken on a set date and two months later no reinstall and no structured ticketing — a concrete red flag about long‑term responsiveness.
Paul reached out to 1 Solar Solution more than seven months ago after his new solar panels produced no power. Multiple technicians came to the house and eventually diagnosed a failed inverter, but the repair never materialized. The techs handed him off to a representative named Zarman, and that's where the timeline unraveled. A few texts about replacing the inverter gave way to weeks of silence; he followed up weekly, was told the part had been ordered, and then was told supply-chain issues in China were delaying delivery. That explanation didn’t come with timely updates — since September he chased countless emails, texts, phone calls and voicemails and got maybe three responses, none of which moved the fix forward. Frustrated, he turned to advice from other reviewers and plans to contact Universal Solar instead, wishing he had seen those reviews sooner. The concrete outcome: seven months later his panels remain without power, the fault traced to a failed inverter, and the most memorable facts are the long delay, the point of contact named Zarman, and the near-total lack of useful communication.
Mukesh had 1 Solar install his rooftop panels about four years earlier, and everything worked smoothly until the array stopped producing electricity in August 2021. He called 1 Solar on Aug 10, 2021, and when the operations line didn’t pick up he chose the sales option; a representative named Zerman answered, was pleasant at first and promised a one‑day turnaround. A few days of silence followed, then more calls where Zerman said he was looking into it and later that limited resources meant it would take a couple of weeks. Weeks slipped by, calls and texts went unanswered, and a visit to the office address Mukesh found on Google turned up no office at that location. After about six weeks of no meaningful support, he reached out to another company, Universal Solar; even though he wasn’t their customer, they sent a technician within two days and had the system working again in roughly 15 minutes. The standout detail: six weeks of being ignored by the original installer versus a 15‑minute fix from another vendor — the fast resolution from the second company is what stuck with him.

Three years ago Warmanvijay hired Ali Samana and 1 Solar Solution to install solar on his home, and Ali warned up front that whoever he picked would be the company he'd deal with for the next 25 years—so price shouldn't be the only factor. He discovered how important that advice was when he needed service later: two of the other companies that gave him quotes folded, while 1 Solar kept growing and stayed reachable. Every time he called, a live person answered and a technician showed up at his house the same week, even for a minor problem. He appreciated being treated like a valued customer and now sends clients their way because he knows 1 Solar will actually respond and follow through.
olknight hired Solar-1 for an initial 9 kWh system on his home and returned two years later for a 2 kWh add-on. They discovered that both projects delivered exactly what had been promised: competitive pricing, tidy and professional installations, prompt responses to calls and questions, and—when required—well-organized tax paperwork. The installations performed as expected and provided clear value, which is why the homeowner chose the same company a second time. The detail that sticks: the add-on integrated smoothly with the original system and the administrative side never became a headache.

Ankur had One Solar install a rooftop solar system three years ago, and the array has performed reliably while the company stayed available for support. He found the standout moment came when he needed a roof replacement — One Solar stepped in, coordinated promptly with his roofer, and kept the work moving without unnecessary delay. Over the three years they remained helpful and responsive, and what stuck with him was that the company didn’t disappear after installation but actively worked with other contractors when it mattered.
Ramesh had 1 Solar install a rooftop system built with LG solar panels and Enphase microinverters. A year in, he’s enjoyed smooth, trouble-free operation with no problems to note. The detail that stands out is the simple, reliable first-year performance — no callbacks and no glitches.

Josh C hired Design 1 to put solar on his home and ended up cutting his electric bill in half. The crew installed the system and returned to service it whenever something came up, so he didn’t have to chase repairs or paperwork. What stood out was the tangible savings — a 50% drop in his bill — combined with a responsive team; he credits D1G for both the installation and the follow-up support.
Pinky N needed her home's solar panels reinstalled, and a representative from the solar solutions team handled the job promptly and professionally. The rep stayed on top of every step—coordinating schedules, following up from start to finish, and clearing up loose ends—so the reinstallation stayed on schedule. She ended up with her panels back in place on time, with the standout being the rep's consistent, end-to-end follow-up that kept the project moving.
Lil Augie hired the company for a rooftop solar install and discovered the crew left anchor points on the roof. They soon had water coming into the house and traced the leak back to those leftover anchors — the installation itself left the roof vulnerable. The standout detail is how a simple piece of forgotten hardware turned into interior water damage; a clear takeaway for buyers is to inspect the roof and any penetrations before the crew finishes and to demand proper sealing of all anchor points.
