This company's post-sale support has essentially collapsed. We found 18 reviews describing installation delays stretching months, systems going dark with no fix, and customer service lines that ring straight to voicemail. One homeowner paid for panels in November 2021, didn't get them operational until April 2022, then got hit with a $5,000 true-up bill a year later because the system underperformed. When he reached out, the sales rep who had checked in ghosted him. Another customer's panels stopped working after three years, she called repeatedly for help, and staff promised callbacks that never came. She's now stuck paying both her solar loan and a $2,500 supplemental electric bill. The pattern is consistent: friendly sales process, then silence when things go wrong. Several reviews mention LarSun was sold to another company that no longer exists, leaving customers with broken systems and no one to call. (One reviewer had to give five stars just so people would see her warning. That's how bad the communication breakdown is.) If you're weighing quotes, understand that the warranty and support structure you're buying into today may not exist a year from now.
If you value post-sale support, this is not a safe bet. The company was sold, and multiple customers report unanswered calls, stalled repairs, and surprise electric bills when their systems fail.
Sonny ended up facing a shockingly large true-up bill—more than $5,000—a year after his home solar system finally went live. He bought the system in November 2021, waited through an installation that didn’t happen until February 2022, and didn’t see the system operational until April 2022. The salesperson, Andrew, reached out on March 15, 2023 to ask how the system had performed; after Sonny told him about the big true-up charge, Andrew stopped responding. He found the company’s customer support unreachable as well—calls go straight to voicemail and don’t even ring—so follow-up attempts went unanswered. The experience ended with a hefty bill and no meaningful response from either the rep or the company.
Sarai M. gave the company five stars just to make sure her warning would be visible. At first everything looked ideal: the salesperson impressed her and the rooftop installation went smoothly on a house that had relied on the panels for about three years. Then she received a shocking $2,500 bill from Edison labeled a "supplemental bill for the year." When she and her family inspected the array they discovered the panels hadn’t been producing, even though they were told the company had come out to service them about a year earlier. She called repeatedly, left voicemails, and heard staff promise callbacks that never came. Now she faces the surprise Edison invoice while still making monthly payments to the solar company, and the breakdown in service is what stuck with her — a smooth sale and install followed by disappearing customer support and a hefty, unexpected charge. Her takeaway: the installation started well, but the lack of follow-through when the system stopped working created the damaging, costly outcome.
Tyler S. had LarSun install a residential solar system in 2020; it worked fine for years until, two months ago, the array stopped producing any power. He investigated the outage and discovered LarSun had been sold to another company that now appears not to exist. He ended up with a nonfunctional system and no company to call for repairs or support. The most striking detail: a system that delivered for years became completely orphaned after a change of ownership, leaving him with equipment but no service path forward.

J. G. hired LarSun for a combined roof job and an electrical panel upgrade on their home and ended up with a mixed experience. They discovered the roof crew only installed half the gutters and dented the front-side gutter with a ladder; after complaining and sharing photos with their main point of contact, nothing was fixed. When it came time for the panel upgrade the point of contact advised against it, even though the existing panel was too small and LarSun had already used the HVAC slot—without confirming that change with the homeowner. They had to call SDGE themselves to confirm that trenching or a larger service wouldn’t leave them “without power for a month,” and an SDGE technician cleared the work before installation proceeded. After installation the job wound up handed off to a separate service company for solar issues; two panels aren’t producing and the service firm hasn’t shown up despite several outreach attempts. On the plus side the system runs at roughly 85–95% capacity, the roof shows no leaks, the panel upgrade ultimately passed inspection quickly, and the stucco patching around the new panel matched well. Most installers were friendly and the point of contact was丁

Beth V. had a residential solar array put on her roof on November 8, 2021, and the physical installation went smoothly — but the paperwork and follow-up collapsed. By January 10, 2022 the panels still weren’t operational because the office didn’t communicate after the staff member managing her account left; open orders sat untouched and she had to call several times to get any movement. Frustration built as bills arrived for December and January while the system remained offline, and she felt like giving them zero stars. The company’s owner then reached out personally, apologized, and offered to cover any utility bills that showed up after the installation. That direct, corrective step — paying post-installation bills — shifted the experience from unresolved anger to a clear effort to make things right, and that commitment is what stuck with her.
Rene wrestled with a crowded field of solar options — meeting with several companies, including a big name like Sunrun — before landing on a family-oriented installer. They discovered that Larsun combined top-tier panels and microinverters with a price that felt unusually fair, and ultimately opted into Larsun’s ownership program. The turning point came from working with Kim: she walked them through every question with clear, confident explanations and transparent answers, turning frustration into confidence. The company’s customer-focused approach kept the process smooth, and they’re already planning to send friends and family to Kim when those neighbors start shopping for solar.

David had switching to solar on his list of home improvements when a respectful salesperson knocked on his door and he agreed to a consultation. The rep returned on the scheduled date with Nicole, who laid out the plan — system layout, costs, and warranty — and the numbers made sense because the loan payment came in lower than his electric bill. About a month and a half later, after the city cleared the paperwork, installers George, John, and Adrian arrived and completed the entire installation in a single day; the array looked tidy and professionally done. The inspector came the next day, approved the work, and flipped the system on — the concrete takeaway being a lower monthly payment and a one-day install that was energized almost immediately.
Glen M. moved into a house that already had a solar system and quickly discovered a messy chain of ownership: the original installer was bought out, the buyer went bankrupt, and he wound up having to arrange a third-party maintenance contract. He paid $900 to HES Solar for an annual service plan, but HES took the money and then went silent—ignoring texts, emails, and voicemails. He remains stuck without confirmation that the array actually works or even a list of the components installed on the roof, left with a paid-for contract and no way to verify the system’s status.
Jaz C. discovered the solar installer had abruptly closed when she went to schedule a roof repair after rain damage. They found the panels are still producing power, but the company’s shutdown wiped out their warranty. Now they’re scrambling to find a contractor willing to lift and reinstall the working panels for the roof work — worried the removal could break modules and leave them with both repair bills and no warranty protection.
Long-term satisfaction for LarSun Solar drops to 2.3 ★ compared to early reviews. This is better than 42% of installers we looked at.
Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
