Sun Solar reviews

The Verdict
Sun Solar doesn't belong on your shortlist. We analyzed hundreds of reviews and found a company that leaves too many customers stranded with underperforming systems and vanishing support. One homeowner's system was down for 8 months due to a faulty breaker tripping daily. Despite repeated calls and emails, nobody showed up. Another paid $80,000 for panels and two battery units, only to discover Sun Solar installed just one battery. It took six people in a meeting, charts in hand, before the company admitted the mistake. That same customer still owed PG&E $1,800 at year-end despite the corrected install. Across the reviews, we found 56 accounts of performance failures: systems producing far below the promised output, batteries misconfigured to use only 20% of their capacity, and repair requests ignored for months. The workmanship score is solid (4.4 out of 5), which tells us the installers do clean, competent work. But post-sale support scored just 3.5, and value scored an even lower 3.1. Early adopters praised responsive staff, but recent reviews paint a grimmer picture. The president stopped returning calls, leaving one homeowner with torn stucco and a state contractors board complaint.
If you want a solar company that shows up after the sale, keep looking. Sun Solar's install crews are competent, but you're gambling that your system won't need support, because reviews show the company often disappears when problems arise.
Reviews That Shaped Our Verdict
R M. began a residential solar project in 2024 after agreeing to a contract that originally included Tesla batteries, but the first sales rep went dark by October 2024 and it took months to get anyone to follow up. When a new representative picked up the job in 2025, Sun Solar shifted to SolarEdge equipment and installed the panels and battery in August 2025. The Los Angeles County inspector failed the installation because the battery sat about three feet too high; Sun Solar moved the battery to pass inspection but left significant stucco damage and an exposed pipe visible from the front of the house. After the correction, the company stopped answering calls and texts for roughly two months, including attempts to reach President Scott Ryan and the operations manager. R M. delayed writing a review in hopes the company would repair the visible damage, but by 10/23/25 the house remained unrepaired. Frustrated by the lack of follow-through and multiple workmanship issues, they filed a complaint with the California State Contractors' Board.
Gypsy D. ended up $80,000 into a solar system on her 1,800 sq ft house and still owing PG&E every year. In November 2020 she purchased 36 of the highest-output panels available plus two 13 kW battery storage units the installer billed as better than Tesla, and was assured she wouldn’t receive a true-up bill because the system would generate more than the home used. Instead the reality unfolded very differently. Her husband, who watches graphs and charts for a living, discovered the numbers didn’t add up and pushed the company for answers. Sun-Solar initially insisted everything was fine until the couple assembled detailed charts and forced an in-person meeting with six staff members. Faced with evidence, the owner Scott and a technician came out and found only one battery had been installed despite payment for two; they apologized and installed the second unit. Even after that fix, the system never performed as promised. The first year brought a year-end true-up of $1,200 on top of a roughly $450 monthly loan payment, and the next year’s true-up climbed to $1,800. The family stopped daily monitoring for lack of time, which they acknowledge hurt them, but customer service initially,
Tina M. installed a system that initially covered more than 100% of her household needs and wiped out her electric bill, but the picture unraveled over a few years. She watched true-up charges climb: after the first two years of zero true-ups she ended up with bills of $700–$900, and now the shortfall looks like it will balloon to $2,000–$3,000 or more. Her contract had guaranteed 103% production, yet the company kept emailing that the array was “producing 96% after 6 years” — a claim that felt out of step with her contract and with what she was seeing at her meter. No technician showed up as promised in the last two years, despite repeated calls and emails that went unanswered. For roughly eight months a separate breaker the company installed has been tripping daily and shutting the whole system down; sometimes the alerts arrive days later, so she doesn’t even know the system is offline until she discovers the breaker has tripped. Meanwhile the company continues to withdraw monthly payments from her account and sends messages claiming the system is “working as it should.” When she begged for service she was told there was a long list and no staff to make repairs. She edited an old

David F. discovered that the rooftop solar system Sun Solar installed on his home had been tied to the wrong electric meter. For a year and a half he produced solar power that never showed up on his account, ended up with a $3,500 PGE true-up bill, and never received credit for the thousands of kilowatts he returned to the grid. He tried repeatedly to reach Sun Solar, but the company stopped returning calls, refused to accept responsibility, and would not speak with PGE even after PGE asked them to. Frustrated and out the expected financial benefits of the system, he is preparing to pursue legal action to recover what he’s been paying for but hasn’t received.
Joshua Philley bought a residential solar system after receiving assurances that everything would be covered by warranty and that a simple service call would handle any inverter problems. About a year after the array went live, he discovered the company had been bought by another firm that stopped honoring those original agreements. Within that first year one inverter failed on a single panel, and the new owner refused to come out to inspect it without charging for the visit. On top of that, the company began charging $10 per month for full access to the monitoring app that shows panel production and flags issues. He ended up stuck with a failed inverter, no free warranty service, and an unexpected subscription fee — the two details that stand out most from his experience.
