Sun Energy reviews

The Verdict
Sun Energy has a serious track record of taking customer money and vanishing. We analyzed nearly a hundred reviews and found a disturbing pattern: multiple homeowners report paying tens of thousands for unfinished work, then watching the company go silent. One customer paid for a $100,000 project that included solar and a bathroom addition. The solar went in, but the construction never happened, and the owner stopped returning calls. Another signed in March 2021 for solar and a fence wall, paid through August, and by February 2022 was still staring at a half-built fence and unreturned voicemails. The company also fumbled basic execution on completed projects. Sixteen reviewers mentioned roof gaps, leaks, inverters installed out of range of batteries, and systems that never hit promised performance. One homeowner discovered a significant gap between the den and garage walls after a re-roof, confirmed by Sun Energy's own roofer, then couldn't get anyone to fix it because all phone numbers had full voicemails or were disconnected. The 33 positive reviews praising responsive staff like Jose and Nicole date mostly from 2020-2021. The negative reviews alleging abandonment and fraud cluster in 2022-2023. If you're comparing quotes today, you're rolling dice on whether this company will finish your project or leave you holding a loan for work that never gets done.
If you want solar installed and actually turned on, look elsewhere. This company has a documented pattern of collecting payments and disappearing mid-project.
Reviews That Shaped Our Verdict
Sagar D. signed a contract in March 2021 for a front-yard fence wall and rooftop solar, with the job due to finish by August 2021. By that deadline the crew had only trenched the yard for the fence, leaving a trench he had to live with for months while neighbors commented. He began making loan payments in August to Mosaic—the lender—and discovered the financing was entirely separate from the construction company, so stopping payments wouldn’t halt the unfinished work but would damage his credit; Mosaic declined any responsibility for project completion. In October Steve Brennan, the director of operations, admitted the original price was too low; Sagar offered to split the difference, adding $15,000 to the contract, and brickwork and the solar install finally started in December. By February the solar array sat installed but not yet hooked to SoCal Edison, and the fence was about half done, still needing brickwork, iron fencing and a gate/motor; the Edison paperwork was only completed in April. As of August 2022 the fence had sat unchanged for roughly six months. He continued paying to protect his credit while the project manager had departed and the company still hadn’t named a PM
Kristi hired SunEnergy in March 2000 to re-roof her house and install a whole-house solar system. In February 2023 she discovered a significant gap where the den meets the garage — an improperly installed roof opening the door to potential secondary damage. SunEnergy sent a roofer who confirmed the installation was faulty, but the contract limits repairs to SunEnergy contractors only, so she now faces a catch-22: she needs the company to fix their own work, yet she can’t get them on the phone. Phone numbers listed on the website go straight to full voicemails that never get cleared, and the direct cell numbers she was given are disconnected. Kristi also expected an oversized solar array that would eliminate her electric bill; instead she kept paying and never received a proper assessment or explanation despite repeated requests for a site visit. On top of the structural and performance problems, the crew left the garage and den covered in dirt and sand and ruined a brand-new leather sofa by failing to protect the interior during the 2000 work. What lingers most is that SunEnergy acknowledged the roof defect but is unreachable — blocking her access to the 10-year roof warranty and
Jessica decided in April 2021 to put solar on her ranch-style home and received a roughly $30,000 proposal from Sun Energy. The owner, Dennis Jay, came to her house and — while she mentioned wanting to add a master bathroom — offered to fold construction into the deal after telling her she qualified for a $100,000 loan; he persuaded her to move forward. She met with a designer who later advised that the funds left after paying for the solar wouldn’t cover the bathroom, so she asked the company to readjust the loan and skip the construction; she assumed they had done so. The solar array went up in August 2021, but she soon discovered the loan had never been changed and communication deteriorated. Over the following months she endured long stretches of silence, sporadic site visits for measurements, and a January 2022 call from a project manager who claimed not to have known construction was part of the scope but promised to start permitting. When she pressed Dennis Jay directly, he briefly offered to cover her loan payments until the build was finished; she declined and asked for her money back instead. After more unanswered emails, the company finally replied only after a Yelp post

What You Can Expect
Corina H. had solar panels installed five years ago and later discovered a leak beneath the array. She waited two weeks after the company promised to send someone to inspect the problem, but nobody ever contacted her and her calls went unanswered — she felt completely ghosted. Angry and distrustful, she accused the company of being crooks and intends to file a complaint with the BBB.

Eric signed a contract in late April 2022 for a rooftop solar install that was supposed to be finished in eight weeks with no obstructions. He quickly ran into delays: the agreement needed to be revised because the company was having trouble with their bank, and then the installer crews changed — he had to stay home three different times to let three different roofers onto the property while the company sorted its subcontractors. Communication dried up next; the project manager went weeks without responding, and inventory problems forced a second contract change to a different panel model. After repeatedly calling and waiting, the array finally went up about a year later — but it wasn’t producing. The bank began billing loan payments once panels were physically on the roof, and Sun Energy promised to reimburse those charges; Eric had not seen that reimbursement when he wrote. Four months after installation the system started operating, making the total time from signing to live production roughly one year, and leaving him frustrated by the slow timetable, repeated contract revisions, and the unpaid loan bills while the system sat idle.
