Sunpower by Hyperion Solar Energy reviews
• last updated FEB 26, 2026Loading map...
The Verdict
We found a split-decision pattern: some homeowners saved money for years without incident, but others paid five figures for systems that stopped generating power and couldn't get help. One reviewer in New Jersey described panels sitting dark for months while support tickets went unanswered, eventually leaving them with both a $600 electric bill and a lease payment. Another spent over $30,000 in 2021 only to discover two years later that warranty claims were denied and Hyperion stopped returning calls. The sales process earned consistent praise for patience and responsiveness, especially from reps like Mike Sgambati and Ian, who stayed in touch after contract signing. But post-installation support is where things fracture. We found multiple reports of conduit leaks, failed inspections, and systems that never passed utility approval, with some customers waiting years for resolutions that never came. If you prioritize upfront guidance and panel quality over long-term accountability, you might tolerate the risk. But if you need a company that will still pick up the phone when something breaks in year three, the evidence suggests looking elsewhere.
If you're evaluating purely on sales experience and panel specs, you'll hear good things. But if you need confidence that the company will fix a broken inverter or flooded conduit two years from now, multiple reviews suggest they may not answer your calls.
Reviews That Shaped Our Verdict
Ian M. invested more than $30,000 in a solar system installed in late 2021. Now he has a system that produces no solar power; SunPower denied warranty coverage for the problem, and Hyperion has not been returning his calls or emails. After a sizable upfront investment, he ended up with a nonworking system and no responsive contractor or warranty support — the combination that stuck with him.
Jason K. had a SunPower solar system that sat idle for two years. Hyperion reached out, worked with SunPower to sort out the problem, and got his system repaired so it was producing energy again. He found the team professional and appreciated that they walked him through the right process — contact your dealer first instead of going straight to SunPower — a practical tip that helped restore two years of lost generation.
Ahrum H. was already researching solar when a SunPower representative knocked on her door; curious, she agreed to listen. Meetings kept getting pushed around because of last-minute conflicts, but Mike Sgambati stayed flexible and rearranged his schedule until they finally fit in a 1.5-hour session. After a string of texts and email follow-ups, she decided to go with Hyperion and SunPower. Once the contract was signed she hardly had to lift a finger: the team handled town and PSEG permits and kept the process moving. Although she was warned panels were backordered and installation might take a year, the system was up and running in about four months. Even after activation, she continued to have questions about bills and system guards, and Mike stayed responsive and reliable through every follow-up. The detail that mattered most to her was not just the quicker-than-promised timeline but that the relationship continued beyond the sale — Mike kept managing the loose ends until the system performed as expected.

What You Can Expect
A year after installing a SunPower system on her home, Kim F. still opens the utility bill to find a negative balance each month. She met sales rep Kevin Dashner at the first appointment, and he walked her through the options; the installation itself went smoothly and the crew followed up promptly afterward. The whole process felt professional and transparent, and she ended up with clear value for the price — not the cheapest option, but one that delivers. Her only regret is that she didn’t make the switch sooner; the steady monthly credits and solid post‑install support are what stuck with her.
Amy found the standout in Andrew from Hyperion, who dug up multiple quotes from other companies and kept pushing to find a solution when the parent company stalled. She ended up with panels and a fast, clean installation—the local Hyperion crew handled the work efficiently and stayed available to help throughout. The only real hiccup came after install: the parent company was slow to respond and reluctant to take charge of the issue. Because of Andrew’s persistence and the smooth on-site work, she would hire Hyperion again if she had another property, but she only has the one roof to use them on.
Ian W. chose a SunPower solar array with a backup battery for his home and ended up with an electricity bill reduced to zero. He paid more upfront than cheaper options but valued the build quality and components. SunPower’s team stayed on top of the installation and followed through through commissioning, so the system performs as expected. The clearest takeaway: the battery-backed SunPower setup eliminated his monthly electric charge, which made the higher price feel worthwhile.
