LarSun Solar reviews
• last updated FEB 26, 2026Loading map...
The Verdict
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.
Reviews That Shaped Our Verdict
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.
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.

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.
