HelioPower reviews

The Verdict
HelioPower installed systems that routinely failed to deliver promised savings, then disappeared when customers needed help. We analyzed nearly a hundred reviews and found a clear pattern: professional installations followed by expensive utility bills and unanswered service calls. One homeowner paid $40,000 for a system HelioPower promised would eliminate their electric bill, only to receive a $3,000 invoice from Edison a year later. When they called for help in January, a technician finally showed up five months later and said "sorry." We found 40 reviews mentioning poor post-sale support and 45 citing project management failures. The problems go beyond slow callbacks. Multiple customers reported mechanics' liens from unpaid subcontractors, systems wired incorrectly that produced only 60% of expected output for years, and roof damage that led to interior water leaks. One customer's final inspection failed four times due to broken tiles, missing flashings, and rails sealed to dirt instead of felt paper. The inspector called it a "nightmare." By 2020, many phone numbers were disconnected and the company appears to have gone bankrupt, leaving customers with broken systems and no recourse. (Yes, one reviewer had to hire lawyers just to find out why their panels stopped working.)
If you're researching HelioPower because you found them in old search results, walk away. The company is effectively defunct, support has evaporated, and the reviews show a years-long pattern of systems that never performed as promised followed by total radio silence when things broke.
3 Stories That Stood Out
John W. invested $40,000 in a Helio solar system after being assured it would wipe out his Edison bill. About a year later, in January, he was hit with a $3,000 charge from Edison. He called Helio right away that month, but the company didn't come to his house until yesterday — five months after his initial call. When the technician finally arrived, they offered only an apology, and he told them to get out of his home. He left the whole experience with a large unexpected bill, long delays for service, and a one-star review.
Roger V. hired HelioPower to install a home solar PV system with a battery backup — the battery was the primary reason he took the project. He discovered the contract didn’t meet CSLB guidelines, and the job quickly turned chaotic: the company set a price, came back a month later demanding double, then later promised to “honor the agreement” so no change order was provided. Without notice, crews showed up before 8:00 a.m. one morning and he had to clear his schedule for weeks; after work began, about 100 days after signing, the company pushed a new Addendum A that “replaces the original” and demanded full payment and a signature. An installer told him they were instructed not to return without the signature and the check. He found widespread workmanship and safety failures. Components were installed incorrectly, the battery backup suffered a bait‑and‑switch and the wrong inverters were delivered. The permit didn’t even list a battery backup. HelioPower installed a single, inadequate bank of batteries with no proper cabinet or ventilation — a configuration he identified as a serious fire and explosion hazard and prevented from becoming catastrophic. The system failed final city/
Rosemary had Heliopower of Murrieta put 23 solar panels on her roof a few years ago. The install itself went smoothly — crews were polite, on time and left the property clean — and the price looked reasonable for a household whose electric bills rarely topped about $120. What followed, though, became the core of her complaint: power bills climbed dramatically after installation — roughly $400 after the first year, about $600 the next, and around $800 most recently — and pigeons began nesting under the array. She phoned Heliopower to ask for help; a promised callback never happened. When she finally reached the office again, staff said there were no notes from her earlier call, insisted on an $85 service fee and sent an e-sign authorization she quickly completed — only to be told later it hadn’t been received, forcing her to download and resend the form. The scheduled technician, booked for 1:30 p.m., arrived early, left, then returned at 2 p.m. (a local contractor at the house witnessed the back-and-forth). The tech tapped the inverter, made a phone call, declared the system operating normally, took her husband’s credit card and left. When asked about installing bird screens, he答

What You Can Expect
A. D. had solar panels installed a few years earlier that kept leaking into the son’s bedroom whenever it rained because the original installer hadn’t sealed the mounts; that earlier contractor later went bankrupt. When HelioPower came out, technician Josh Basara diagnosed the leak immediately and discovered that water had pooled in the junction boxes on the roof, short‑circuited about half the panels and driven the electric bill up. Josh explained the problem and the repairs in plain language, stayed available for questions into the evenings and even gave his personal cell number. A. D. dismissed online rumors that HelioPower had gone bankrupt as incorrect and made clear that if any future issues appear, Josh is the one person they will call.
Paul G. hired the company to install a ground-base array and quickly discovered they refused to honor warranties or service the equipment. He found the crew left the installation incomplete, then balked at finishing or returning to fix problems. When rodents got into the ground-mounted gear, the installers acted surprised rather than offering a solution, which left him dealing with exposed wiring and damage. He concluded their engineering work was amateurish and ended up with an unfinished system that the company wouldn’t stand behind — the most striking detail being their apparent surprise that a ground-mounted array could be vulnerable to rodents.
John W. invested $40,000 in a Helio solar system after being assured it would wipe out his Edison bill. About a year later, in January, he was hit with a $3,000 charge from Edison. He called Helio right away that month, but the company didn't come to his house until yesterday — five months after his initial call. When the technician finally arrived, they offered only an apology, and he told them to get out of his home. He left the whole experience with a large unexpected bill, long delays for service, and a one-star review.
Adrian G. had Heliopower install a rooftop solar system on his home about two and a half years ago, and they used a low-profile mounting method so the panels sit close to the roofline. Over time he ran into some monitoring glitches, and Heliopower recently upgraded the system electronics — a job handled by Nick Sandoval, an on-site technical wiz who completed the upgrade. When a small issue popped up again last week, Francis at Heliopower dispatched Nick the next morning and the problem was resolved on the spot. He walked away impressed by the company’s responsiveness and the way they stand by their work; the standout detail was the quick next-morning return of a skilled technician who fixed things immediately.
Elliott F. had Helio Power install a three-year-old solar system on his home, and it ran without problems until an electrical short knocked out one of the system’s three units. He reported the fault and reached out to the company; Danielle handled the call and made the service process smooth and helpful. He had dealt with Helio Power before for a previous repair and worked directly with Nick Sandoval then — Nick came out, walked him through the diagnosis and fix, and demonstrated clear technical mastery. After three years and two service interactions, he gave them five stars, and what stuck with him most was Nick’s patient explanations and outright professionalism during the repair.
Louie spent the past year struggling with solar panels that weren’t producing as they should on his home. When a technician finally came out, he discovered the system wasn’t operating properly, but after that visit he received virtually no customer service. He has been waiting four months for a repair and was told the resolution could take anywhere from four to six months, leaving him frustrated by the long delay and lack of communication.
Larry H. had HelioPower install his solar array more than ten years ago and ended up with a system that produced strong output, giving him an early return on the investment as one of the first adopters in his neighborhood. When his SunnyBoy inverter started acting up last year, HelioPower showed up quickly, contacted the manufacturer, and reset the unit. This summer the inverter misbehaved again; they returned, reset it a second time, and walked him through how to perform the reset himself — without ever pressing him to buy a new inverter or upgrade other components. In August the inverter finally failed for good. Although it had a five-year warranty, it lasted more than a decade; HelioPower promptly provided a replacement quote and scheduled the swap. The technician arrived 30 minutes early, explained the work, completed the exchange with only a short power interruption, and then demonstrated the new display and explained the readings. The job finished in less time than the two-hour estimate. Across installation and service he experienced a friendly, responsive, professional team that focused on practical fixes rather than hard sells — and the standout detail was how quickly they教
Cindy G. bought HelioPower panels a few years ago and paid to add a Zigbee module so she could monitor the system on her California home remotely from her house in Texas. When the inverter failed, HelioPower replaced it under warranty, but after the swap she could no longer connect through the app and has no way to verify whether the new inverter is working. She tried calling for support and found most HelioPower phone numbers out of service; the only line that picked up went straight to a full voicemail and follow-up vanished. Left without functioning remote monitoring and effectively no customer support, she regrets choosing the company and is now weighing legal action to force a resolution. The detail that sticks: a paid remote-monitoring add-on rendered useless and no reachable support to restore it.
Mary’s solar project turned into a years-long headache for her house. Her original installation in 2015 damaged the roof, and after significant interior water damage the company finally fixed the roof and reinstalled the panels in June 2016. When the panels went back on, the roof suffered damage again; since then she has been met with promises instead of repairs. Her company contact insisted the prior roof work had been done poorly and that the solar crew hadn’t caused the new problems, but three different people have only come out to photograph the interior damage so far. They keep telling her they’ll make repairs “as soon as it stops raining,” yet the roof remains unrepaired while water is already affecting the inside. The lasting image: inspectors with cameras, no permanent fixes, and a homeowner left waiting while rain continues to threaten more interior damage.
Long-term Satisfaction
Long-term customers rate HelioPower 3.0 ★ — higher than early reviews. This growth is better than 97% 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.
