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.
3 Stories That Stood Out
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

What You Can Expect
Shannon had been hesitating about putting solar on her house for a long time, until she met Andrew. He instilled the confidence she needed in the product, the safety steps, and the quality of the installation, so she finally moved forward. Three seasons in, she wonders why she waited. Sun Solar stepped in as a true partner — the whole team kept the process painless, and everyone from the sales agent to the installers treated her and her home with respect and punctuality. She hasn’t had any shortfall between what she uses and what the system generates, and the relief of not worrying about a surprise, high electric bill when the AC runs has been the clearest payoff. If she had to do it again she’d pick Sun Solar without hesitation, and now directs anyone asking about solar straight to them — the most memorable benefit being reliable, predictable bills through the hot months.
A few years ago Ken had Sun Solar install a system on his home, and the whole process felt smooth and well organized from start to finish. Scott took time to explain how solar works and to lay out the available options, answering every question so he understood the plan. A couple of months ago the system developed a problem, and the Sun Solar team jumped into action—diagnosing and resolving the issue within a couple of days. What stuck with him most was the combination of a patient, detail-rich consultation and the team’s rapid, effective follow-up; those two things turned a good installation into a dependable, long-term upgrade for his home.

sryan1984 bought a dream home on 10 acres in 2023 and discovered that, despite existing panels, he still faced a hefty true‑up bill from PGE. Sun Solar stepped in, retrofitted the old system, added panels and a battery, and the upgraded setup has run flawlessly. When high winds or blackouts knock out PGE, he now has convenient, reliable backup power on the property. He singled out Blake and Ryan for doing a great job, and left the project satisfied — the retrofit eliminated the true‑up problem and kept the lights on when it mattered most.
Randy has relied on Sun Solar for more than seven years to keep the system at his home operating. Over that time he’s phoned them whenever questions popped up or a repair seemed necessary, and each call brought prompt, courteous, professional assistance. After seven years of service, the most memorable thing for him is the consistent, helpful human contact — knowledgeable support on the line whenever he needed it.
Bill Clark had trusted this company twice—they installed panels on a home more than a decade ago and on his current house more recently. In June he began getting monitoring alerts and reached out under warranty; approval for a repair stretched out, and nearly three months later a technician finally showed up. The tech informed his wife the job was finished, but the alerts kept coming and Bill started receiving past-due invoices by email for a $250 service fee. When he followed up, the company explained the crew had only been authorized to replace a different component, not the failing panel that continued to cause the alerts — and nobody had told them the first visit wouldn’t fix the issue. Now they say they need separate approval to replace the bad panel and would charge another $250 service call. A couple years into ownership of the newer system, he feels stuck and is even considering doing the repairs himself, since he can buy the parts for less than the company’s service charges. The detail that sticks: being billed while the system still failed and facing repeated $250 fees for each additional approval.
A few years ago Ken Austin had Scott from Sun Solar install a residential solar system, and the work quietly reshaped how his home uses and pays for electricity. He moved through a smooth process from the initial consultation to the final hookup, with Scott and the crew demonstrating clear expertise and staying focused on making sure he understood the benefits of going solar. He noticed a significant reduction in his energy bills after the system went live, and the installation itself felt seamless and low-stress. The team stayed attentive, answered every question, and left him confident in the decision and the investment. The detail that stands out for him is Scott’s skilled installation — it delivered measurable savings and made the house greener without drama.
Richard had Sun Solar install a residential solar system about nine years ago and has continued to rely on them ever since. When problems surfaced over the years, the crew showed up with fixes quickly, communicated courteously, and kept returning to confirm the repairs held — never leaving the job until he was satisfied. What lingered with him was the company’s responsiveness and their habit of following up after service calls, turning a long-term installation into an ongoing, dependable relationship.
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.
