Horizon Solar Power reviews

The Verdict
This company has a pattern of vanishing when things go wrong. One homeowner watched crews patch his roof with mismatched tiles, then spent months trying to reach anyone who'd fix it. Another was promised roof-repair support if panels ever needed removal, only to hit a wall of unanswered emails for two years. We found 11 reviews flagging serious value problems: unfulfilled rebate promises, systems that underperform the contract specs, and customers left to mediate disputes between Horizon and its former financing partner after the two companies severed ties. The post-sale support score sits at 2.1 out of 10, with reviewers reporting vanished contacts, ignored service requests, and systems sitting dark while loan payments continue. Sales conduct fared even worse. We saw reports of telemarketers ignoring do-not-call lists, aggressive door-to-door pitches during nap time, and accusations the company changed names to dodge complaints. (One reviewer claims they still operate under an older license to bury regulatory history.) Five positive reviews mention smooth installs and responsive reps by name, but they're drowned out by dozens describing a company that closes the deal, then ghosts you.
If you want panels installed and never need to contact the company again, you might roll the dice. But if you expect anyone to pick up the phone when your system stops working or your roof springs a leak, look elsewhere.
Reviews That Shaped Our Verdict
Kristin P. chose this company after careful research to install rooftop solar on her home, and her biggest worry was what would happen if the roof ever needed repair. She was reassured the installer would handle roof repairs, so she moved forward. That promise turned out to be false. After the system was installed she spent two years emailing the company and chasing answers, only to get the runaround and no help with the roof. She wound up responsible for the roof work despite the earlier assurance. The takeaway that sticks: get explicit, documented commitments about roof repairs before signing—Kristin waited two years for help and never received it.
Chris in Yucaipa endured three years of back-and-forth with this solar company and has now lined up pre-paid attorney services if they don’t fix the problem soon. He discovered the installer had been working with Sunnova, but that relationship broke down, leaving him with a system that doesn’t match the contract’s promises or actual production. After repeated attempts to get the companies to cooperate, he ended up playing middleman between two firms that refuse to take responsibility. Frustrated and out of patience, he calls the whole arrangement a rip-off and accuses them of running a scam. The concrete takeaway: instead of a turnkey solution, he walked away with years of dispute and the prospect of legal action unless the company makes the system right.
Jon S. had already shopped quotes with a few firms, including sister company Solar Spectrum, when a friend steered him to this installer. The project kicked off well: the bid, engineering and permitting moved smoothly, the company navigated the city requirements, and foremen and a punctual crew showed up early (around 7 a.m., despite a roughly 9 a.m. appointment). He even told the crew they could borrow one of his spare roof tiles if they broke one; they agreed they'd let him know. After leaving for work before the crew finished, his wife called to say the crew had cleaned up and the array looked great that night. The next morning he discovered a patch of mismatched tiles on his roof that hadn’t been there before — despite having photos of the crew and the completed job. He has called repeatedly since, been put on extended hold, and even had to chase his salesperson; with the issue still unresolved, he turned to this review to warn others to double-check how roof damage and post-install follow-up are handled and to keep photographic proof.

Jerry S. signed a solar contract in March 2020 and had the equipment installed, expecting a functioning system soon after. In May he received a letter from one of the vendor partners notifying him of a lien on his house for unpaid equipment, which immediately complicated the project. The city of Riverside then rejected the installation five times during inspections before finally passing it in August, and the utility issued an OK to operate — yet the system still hasn’t been switched on, with Jerry left hoping it might happen by Christmas. Along the way he ran into silence from the company, unfulfilled referral payment promises, and damage the crew caused that went unaddressed. The experience centered on the lien notice and repeated failed inspections: those two problems tied up his home and left him without a working system for months.
