The Verdict
This company will leave you paying for power you're not getting while they dodge your calls for months. One customer watched 18 months tick by with a dead system and zero production, still owing every payment while Sunnova blamed her trees, her Wi-Fi, and dirty panels before finally admitting their inverter had been blinking failure codes all along. Another waited through a year of no production, chased Sunnova for credits, bought the panels outright to escape the lease, and still got billed for usage after owning them. We found a clear pattern: when panels fail or need repair, customers report waiting weeks for the first tech visit, then learning a second appointment is required, then discovering their original installer is "no longer partnered" with Sunnova (a fact the company apparently forgets between service calls). The delays compound. One reviewer described calling customer service in the Philippines or Mexico, being read a script, and told a system producing impossible megawatt readings from 12 panels was "performing as it should." Selling your home becomes its own ordeal. Transferring the lease means navigating disconnected phone numbers, canceled service tickets, and zero accountability when installation mistakes like a panel covering a roof vent pipe pump exhaust into your attic. The few enthusiastic reviews cluster around smooth initial installations and early-year savings, but the volume of disaster stories drowns them out.
If you want solar panels you'll still be paying for when they stop working, and customer service that will insist your broken system is fine, Sunnova delivers. If you'd rather avoid months of runaround while a dead inverter costs you money, look elsewhere.
3 Stories That Stood Out
Suzi T. got a SunPower solar system installed in 2011 by a contractor called Solaire — a company that folded soon after finishing the job. For 14 years she has handed monthly payments to SunPower while watching the system underperform: it missed the production guarantee in 9 of those 14 years, and for the past 18 months it has produced nothing at all. Despite that, her payments continue without interruption. Her contract spelled out three clear responsibilities for SunPower: assign a new contractor if the original installer went out of business; reimburse and fix the system when it underperforms; and uphold a 20-year warranty by addressing equipment issues. In practice, SunPower never stepped in to assign a replacement contractor, never reimbursed for underproduction, and repeatedly refused to acknowledge or resolve the problems she raised. Over more than a decade Suzi has kept calling. Each time SunPower responded with a different homeowner-side cause: first her trees, then her Wi‑Fi, then dirty panels. The trees they flagged only shade a tiny corner of two panels for about ten minutes in the afternoon; she cleans the panels herself; and she was using working Wi‑Fi in her home
Derek T. arranged to have his rooftop solar array removed and reinstalled so his house could get a new roof, and he ended up having to contact the third‑party installer Sunnova had identified to get the work done. The subcontractor handled the removal and reinstall with steady communication, but Sunnova did not act as an intermediary and actually added confusion to the process; a post‑reinstall performance hiccup was fixed after he contacted the installer and simply informed Sunnova. About a year later, at the end of 2023, he discovered a service interruption and loss of production and informed Sunnova. Sunnova set up a technician visit two weeks out, then said an additional service was required; after a week of silence he was told the original installer was no longer partnered with Sunnova. Because that same partnership breakdown had been the earlier barrier to getting the reinstallation done, he found Sunnova’s handling hard to trust. He provided the installer’s contact details to Sunnova, but ten days passed without even an acknowledgement that the vendor might solve the problem. At this point he plans to contact the third‑party himself to verify status — the clearest takeaway:,
Joshua Gonzalez entered into a PPA with Sunnova in July 2021 when he took over the solar agreement on his first home—a transfer the previous owner insisted on, which in hindsight felt like a warning sign. The paperwork moved smoothly at first and customer service answered quickly, and he even saw a technician come out once to replace failing microinverters. Things unraveled in 2023 when a windstorm damaged the roof. He learned that, despite Sunnova owning the panels, he would be charged to have them removed for roof repairs — a responsibility the PPA did not make clear — and after a long fight with his insurer he faced paying for the roof work himself. In September 2023 he asked Sunnova to start scheduling the removal; a case was opened and he was told they would call back. Two months later he called and discovered there was no progress; Sunnova handed him a third‑party number that was disconnected, then an alternate number that was also dead. After more phone tag and two more months of inactivity, Sunnova cancelled the original service ticket, routed the work to another contractor, and that contractor also cancelled without doing anything. By March 2024 he asked to exit the PPA by

What You Can Expect
Amanda Rogers has been a Sunnova customer for about three years and discovered that the company continues to work behind the scenes to secure every advantage of being a solar customer. She found the overall experience excellent and appreciated that support didn’t stop after installation. The detail that stands out is the ongoing, proactive attention—Sunnova keeps handling background work so she can keep the benefits coming. Three years in, that persistent behind-the-scenes care is what stuck with her.
Tony had been chasing SunStrong Management, LLC for more than a year over a solar array on his home that included one panel stuck at 57% output. After he posted an earlier warning on March 18, someone finally reached out and asked for screenshots from the monitoring app, so he sent 13 images covering a full 12-month span. Even with that record in hand, the company kept giving him the same answer it had given all year: the system was supposedly operating within acceptable ranges. The problem never got fixed, and he was still left with a panel performing far below what he believed was acceptable, despite what the Florida attorney general’s office had told him about that level of output.
Catherine B. ended up stuck with a Sunnova loan for a solar installation, hookup, and maintenance package that never actually delivered solar power to her home. Three years after signing, she still had no working solar energy to show for it. For 18 months she kept making payments while waiting on repeated promises that the local electric company would come out and switch her over from electric to solar, but those appointments never materialized. After asking for the loan to be canceled because no service had been provided, she found the account left open anyway, with collection calls following and the debt eventually sent to collections.
D-SQUARED had Trinity Solar handle the sale and installation of a home solar system, and that part went smoothly and professionally. After the system moved into Sunnova’s post-sales care, they ran into a year of frustration: production numbers didn’t line up with what they expected, and no one could reconcile what the system was producing, what the household was using, and what was being sent to Eversource. They spent more than a year chasing answers and felt talked down to on routine calls. When a technician finally showed up a year later, he discovered two panels were under-producing. After more calls they secured a replacement date; D-SQUARED returned early from vacation to be there, only to find the crew never arrived because Sunnova had canceled the work order without notifying them. Sunnova claimed to escalate the issue, but nearly a month passed with no progress until another work order was opened and a visit was tentatively scheduled two weeks out. The sharp contrast — a crisp installation followed by prolonged, poor post-sale communication and a missed appointment after returning early from vacation — is the detail that sticks.
Manuel and several friends ended up with solar panels from the company when it was still known as SunPower, and the whole experience unraveled the same way for all of them. None of the systems ever worked properly, and the installations were never reported to the city, leaving the homes with panels that never delivered the service they had been paying for. When he tried to get answers, he got stuck on hold for hours without a clear response, and after more than three years of making payments for power they never actually received, he finally gave up. The worst part was the roof damage his home took from the installation, damage the company never owned up to, turning what should have been a simple solar upgrade into a costly mess that followed him long after the panels went up.
Kaipo had kept paying on his solar system for nearly 20 years and, back when it was Pro-Vision Solar, the service had been solid. That changed after Sun Power (Strong) took over. His system went down on August 4, and from there he ended up chasing answers while the bills kept coming. Instead of a fix, he ran into a cycle of delays, empty promises, and what he experienced as repeated false assurances, leaving him feeling like he was paying for a system that was still sitting offline.
Ron had a solar system installed four years ago that was pitched as being overbuilt so he wouldn’t face an annual true-up. Instead he discovered his true-up climbed each year, and this year it topped $4,000. His monitoring app now displays "no activity," so he believes the array isn’t producing, and on top of that he’s noticed interior ceiling cracks he attributes to the added weight. He ended up with a four-year installation that appears to be underperforming and causing structural concerns — the striking combination of a huge true-up, a dead reading on the app, and interior cracks is the detail that stands out.
W. installed a rooftop solar system in 2017 to cut bills and be more environmentally conscious, but over the years the panels barely lowered energy costs and then stopped producing power in mid‑August 2025. They discovered a long, frustrating service gap: a technician was booked for October 31, 2025, then that appointment was cancelled and no new service date has been set. Every call routed them to an overseas customer‑service center whose agents could not resolve the outage, and promised callbacks from supervisors never arrived. Frustrated by mounting electric bills for a system that isn’t working, they stopped paying the monthly lease and were warned that doing so could harm their credit score. They grew increasingly exasperated by what felt like boilerplate apologies, referrals back to the same foreign call center, and the company’s bankruptcy filing — ultimately left holding unpaid lease fees and the risk to their credit as the most immediate consequence.
Dave S. discovered his leased rooftop solar system had stopped producing electricity sometime after December 2023, only realizing it when his bills climbed with warmer weather. He called SunStrong, who tried a few troubleshooting steps by phone, but when those failed he pushed for an on-site diagnosis. After repeated delays they finally set a diagnostic appointment in May 2024 — for August 27th — then canceled it days before without explanation. When he heard the company was in bankruptcy, he stopped making lease payments and kept calling every week or two asking for service; the answers were always no. SunStrong eventually gave him the name of an outside servicer; the tech found the inverter was fried and he had to pay nearly $1,900 out of pocket to get the system working again. He demanded reimbursement because the lease assigned repair responsibility to the owner, and after a long fight SunStrong agreed to pay him back in August 2025. He used that money to make two lease payments within a week, only to find SunStrong had reported those payments as late to the credit bureau — entries he insists were retaliatory. He pushed the company for corrections, supplied documentation, and a
