SunPower reviews

The Verdict
SunPower is a gamble you shouldn't take. We analyzed thousands of reviews and found a company with systemic failures in post-installation support and project management. One customer waited six months for a repair that should have taken days, calling weekly while SunPower claimed a mystery part was on order that never existed. The panels weren't wired together. Another homeowner has spent 42 days with non-functioning panels and mounting losses while SunPower ignores their warranty obligations. The pattern is stark: 962 reviewers flagged value problems, 1,105 cited project management failures, and 1,091 reported post-sale support issues. Communication collapses once you sign. Project coordinators stop responding to emails. Case tickets get closed in the system with no work done. One buyer discovered their "fully purchased" system was actually leased only after the misinformation derailed their home sale. Another has panels sitting dead on their roof for a year because their coordinator's only response is "let me contact the team" followed by weeks of silence. If you're betting $30,000 on solar, pick an installer who'll actually show up when something breaks.
If you're willing to spend months chasing down repair techs and filing duplicate support tickets for systems that stop working, SunPower might work out. But if you expect a company to honor its warranty without a fight, look elsewhere.
Reviews That Shaped Our Verdict
Frank H. discovered the hard way that a small, years-old 3 kW SunPower system tied to an HVAC upgrade would turn into a long, frustrating fight when he needed his roof replaced. He believes Valley Heating and Cooling did the original install; when the roof work required the nine legacy panels to come down and be reinstalled, he chose SunPower again to expand the array and keep everything integrated. The removal and reinstallation process quickly tangled into poor coordination and extra charges: SunPower bounced responsibility between teams, tried to bill him for the removal despite the cost being covered in his original contract, and left him doing most of the project management to get the old panels off and stored in his yard. When the new roof was finished and the panels went back on in late winter/early spring, the legacy array produced almost no power — roughly 400 W instead of the expected 2,500–2,800 W. From day one Frank could see the problem: only a few legacy panels appeared to be connected. With 13 years in satellite operations and decades testing spacecraft software, he read the data and knew where to look. SunPower’s teams repeatedly promised to investigate, then ob
Briana L. chose SunPower after her mother’s earlier in-house install had gone smoothly, but a year after SunPower put panels on her ranch-style home she wound up with a cascade of problems that turned an expected upgrade into a long, expensive headache. What started as a trusted recommendation ended with panels that may not all be producing, a monitoring box that only partially works, and a broken air conditioner that no one will fix because the new main electrical panel was installed and labeled incorrectly by a third-party electrician SunPower hired. Meanwhile she kept paying her solar loan and two months of PG&E bills because the system’s output was invisible while SunPower’s support remained distant. She also never received the promised $500 referral fee for sending a neighbor their way. The project began well enough: the sales rep Ian B. impressed, but the on-site coordination unraveled. Her assigned project manager, Mason V., communicated inconsistently, crews arrived without notice, and SunPower asked to coordinate with roofers only to show up the same day and make those roofers wait while panel supports were installed — work that should have been completed before roofing.
Monish G bought an expensive SunPower rooftop system installed by Seabright after a neighborhood sales push that promised an iron‑clad 25‑year warranty and better coverage than competitors like Momentum or Tesla. He bought into those assurances and moved forward, only to discover problems almost immediately: the SunPower app rarely connected in the first week, so he couldn’t monitor performance, and several panels were later found to be misconfigured and needed an on‑site fix. After that initial visit he lived with two years of low‑level frustration, but the situation unraveled in mid‑March. On March 16 and again on March 18 the neighborhood lost grid power (PSEG repaired the outages), and in the days after Monish and other homeowners noticed the system’s reported generation looked wrong. The app only showed total output, not production by each panel, so isolating faults was difficult. SunPower ran basic troubleshooting — restarting the system and promising a technician visit — but those commitments didn’t lead to repairs. Now many panels sit idle and Monish believes several microinverters have failed. SunPower has been unresponsive about honoring warranty service to fix orswap

What You Can Expect
David O bought a SunPower solar system outright for his home in 2021, and now that the property is in escrow the title company insists the system’s ownership must be transferred to the buyers under *** rules before closing. He dug through the company website and called numerous phone numbers but kept running into dead ends: everything he found pointed to lease programs rather than any process for owned systems. The finance team pushed a form tied to a leased arrangement and could not explain how to transfer the warranty or title to the new owners. With no clear paperwork or guidance from SunPower, the closing on his home is at risk. The detail that sticks: for outright owners, SunPower’s public-facing channels may not provide a straightforward transfer path, and that gap can threaten a sale.
Patrick noticed in early March 2024 that the leased SunPower system on his home was showing zero production in the mySunPower app. He called SunPower on March 6; after remote tests they promised to send a technician and to call back to schedule. He waited, called again on March 8, then repeatedly through late March — March 26, 27 and 29 — and kept running into long hold times and stalled follow-through. Each time he phoned, SunPower pushed responsibility onto their partner, Air Sun, while Air Sun quickly confirmed the hold-up: SunPower had not approved compensation for the work order needed to dispatch a tech to repair the inverter. Patrick spent dozens of minutes on hold during single calls and cycled through multiple contacts without progress. On March 27 he also contacted Southern California Edison, which confirmed the system had stopped producing as of 11/30/24 (the date recorded by his utility). Through March and April he kept paying his $118.47/month lease while receiving no solar service; the outage ultimately stretched to roughly five months and several days. He expected a refund for those unused months. Mid-June 2024 the Better Business Bureau stepped in and connected him:
Yeon moved into a townhome that came with a rooftop solar system installed when the property was built in 2017. In March 2023 the microinverters in the neighborhood failed, and while SunPower fixed the same problem for several neighbors under warranty, Yeon discovered his panels have been unusable for 16 months because SunPower repeatedly refuses to make the repair. The company’s website promises a 25-year warranty covering panels, microinverters, and racking, yet every customer-service contact delivered a different explanation and no fix. One representative blamed storm damage even though Yeon lives in a dry area; a visiting technician said microinverters “need to be constantly replaced”; another response claimed the contract excluded a warranty but then denied Yeon access to the contract when requested. Promises to call back within a business week never materialized, and after more than a year the issue remains unresolved. Frustrated by the inconsistent excuses and the fact that neighbors received warranty service while he did not, Yeon is now weighing a small-claims complaint for what he believes is discriminatory treatment — a striking example of long delays, opaque paperwork,和
