NextEnergy has been installing solar for over a decade, but we found a troubling pattern: stellar service when things go smoothly, radio silence when they don't. One homeowner reported that after 15 years with a flawless system, the company stopped returning calls about a roof replacement that required panel removal. We noticed this isn't isolated: 9 reviews describe unresponsive follow-up, slow repair estimates, or outright abandonment after installation. The workmanship scores well when reviewers can reach them (12 praised installation quality), and one customer received an impressive full 42-panel replacement when a single cell ran hot. But post-sale support scored just 2.9 out of 5, anchored by stories of unanswered emails and vanished sales reps. If you're weighing a solar installer, know that NextEnergy's long-term reliability appears to hinge on whether your system needs intervention. The company has real engineering talent and uses quality components like Enphase and SunPower, but several customers who paid five figures felt abandoned the moment a warranty issue or service request arose.
If you install solar and never need post-installation support, NextEnergy's engineering chops and material choices may serve you well. But if you expect responsive service when equipment fails or you need panels removed for roof work, we found too many unanswered calls to recommend them confidently.
Wallie M. paid $33,000 in 2007 to Nextenergy for a 24-panel SunPower system on his home, and it delivered reliable performance for almost 15 years. When his roof finally needed replacing, he reached out to both Nextenergy and SunPower to arrange removal and reinstallation of the panels and said he would pay for the service. Instead, he was met with silence: calls and emails went unanswered, and an automated voicemail that promised follow-up never materialized. After investing heavily and enjoying long-term performance, he ended up feeling abandoned by both the installer and the manufacturer when he needed help getting the panels off his roof.
Hari B. met Randy Kaufman, owner of NextEnergy, about five years ago when he hired the company to install a rooftop solar system and opted to buy it outright: 42 SunPower panels went up on his house. The installation unfolded almost invisibly — from the first site visit to the final cleanup he barely noticed the crew until one day the system was live. NextEnergy handled all the paperwork and rebates, and mounted three inverters in an unobtrusive spot on the side of the home; those inverters have worked nearly flawlessly ever since. The moment that set the relationship apart came the first winter after installation. Early one morning Hari spotted frost everywhere except for a single 4"x4" cell on one panel. He called NextEnergy and a technician arrived that day, diagnosed the cell as “running hot” (a failed cell), and rather than swap just that panel, NextEnergy removed and replaced all 42 panels — upgrading him to the newest modules that deliver about 20 watts more each. There have been no other issues over the years, and Randy still calls about once a year to check in. What Hari remembers most isn’t just the smooth install but the company’s willingness to replace the entire r0
During a major remodel, Peggy K. had her architect and general contractor bring NextEnergy in to install rooftop solar on her home, with the expectation that the array would produce enough power to earn PG&E energy credits. Instead, she discovered huge utility bills and only a single brief stretch when the system actually sent power back to the grid. Technicians checked the installation and confirmed the equipment was working, and a former sales rep who later operated as an independent consultant ran an in-depth analysis and concluded the system simply wasn’t sized to cover the house and create excess energy. Peggy made her disappointment known but initially chose to live with the shortfall. Later, Randy from the company called cheerfully asking for referrals; when she explained the performance problem he acted like it was the first he’d heard, promised to investigate, asked for utility bills (which she sent), and then faded. Repeated emails and calls went unanswered. Earlier in the project she also dealt with Emma Brown in the office, who phoned the empty job site demanding immediate payment—calling the wrong office, threatening to pick up materials, and never apologizing once the

Samira had Next Energy install a rooftop solar system on her house in 2017, and the array has run flawlessly ever since. She received a true turnkey experience: the team designed the system, pulled permits, secured financing approval, and walked her through the benefits and expected savings. Their 20 years in the business showed up in steady, knowledgeable customer service and the way they navigated paperwork and technical questions. The most memorable detail is the combination of full A-to-Z service and long-term reliability—years later the system’s trouble-free performance feels like the clearest proof of their workmanship.
After eight years of researching solar — and watching other companies fail to show, overprice systems, or leave customers waiting for work to start — Jeanne C. landed a very different experience with Nextenergy. She moved forward with a system that’s been on her ranch-style home for about two years and found the process refreshingly reliable: Farzad answered questions promptly, returned calls, and stayed available throughout the project. Once the contract was signed, crews began work in roughly two weeks, a welcome contrast to the horror stories of long delays she had encountered. The installer used high-quality gear, including Enphase microinverters that let her monitor panel output online — a feature she singled out as genuinely useful. So pleased, she asked Nextenergy for a quote on another house, and Farzad put in the extra effort to shape that proposal to her needs. The detail that stuck with her most: the team actually showed up quickly and she can watch her system’s production in real time.

Michael K. hired Next Energy for a large SMA solar system installed on his home in 2014 and decided on them because they’ve been around and employ seasoned engineers. When a few warranty problems popped up years later, owner Randy Kaufman stepped in and arranged for a qualified engineer to come to the site, troubleshoot the issues, and coordinate replacement of the faulty manufacturer equipment. The hands-on follow-through — the owner sending a skilled engineer and making sure manufacturer parts were replaced — turned a potential headache into a smooth fix. He now treats Randy as his go-to contact for any future solar projects because of that direct, practical support.
Peter A. returned to the company for a second home installation after working with them 15 years earlier. He entrusted them to design a battery backup system, and the team applied up-to-date equipment with a careful, knowledgeable approach. The installation came out immaculate and has been producing better-than-expected results. What stood out most was the crew’s obvious pride in their workmanship and the meticulous battery-backup design that continues to perform.

Karyn F. has had Next Energy solar panels on her house for years with no problems, so it was worrying when she discovered a red light on one panel yesterday. She called Randy Kauffman, who arranged to be at her home the next day. Randy arrived as promised, diagnosed the fault and repaired it on the spot. She walked away reassured by the prompt, hands-on service and the system’s long record of trouble-free performance.
Rick M. trusted Next Energy to fit rooftop solar panels on his home ten years ago, and he has enjoyed both the workmanship and the level of service ever since. He walked away with a durable installation that's kept him satisfied over a decade, and he highlights the company's focus on customer service alongside solid-quality work. What lingers as the main impression is simple: ten years later the panels are still performing and the customer experience matched the job quality.
Alina G. brought NextEnergy in to install solar panels on her home and discovered the system wasn't working — instead of cutting costs her electric bill climbed sharply. The savings the company promised never appeared, and repeated attempts to get help ran into dead ends: the phone numbers listed on NextEnergy’s website wouldn't connect. Frustrated and convinced she had been misled, she labeled the company a scam and is moving forward with a complaint to the Better Business Burrow. The most memorable detail for future buyers: the panels failed to deliver savings and the company proved difficult to reach after installation.
Long-term customers rate NextEnergy 4.5 ★ — higher than early reviews. This growth is better than 100% of installers we looked at.
