Nexus Energy Systems reviews

The Verdict
Nexus Energy Systems is a gamble we wouldn't take. One customer in California called repeatedly for months after their system stopped working, eventually racking up a $732 utility bill on top of their $275 monthly panel payment. Another homeowner is entering year three of waiting for a roof leak fix, with water damage spreading through their ceiling and walls, and Nexus going silent for weeks at a time between replies. We found 43 reviews describing systems that don't produce the promised power, installation crews that damaged roofs or wired batteries incorrectly, and support teams that vanish when problems emerge. The pattern is consistent: smooth sales process, then radio silence when you need help. Sixteen reviewers reported billing disputes where their electric bills stayed high or even climbed after installation, directly contradicting the no-bill or low-bill promises from sales. One reviewer's well pump, wired to a backup battery for wildfire power outages, has never worked correctly despite multiple repair visits. The company does have 165 mentions of solid workmanship and 148 praising post-sale support, but the 43 customers left strung along with unresolved system failures tell you what happens when you land on the wrong side of their inconsistency.
If you're willing to bet that you'll be one of the happy customers and not one of the families waiting years for a roof repair or watching your electric bill climb while your panels sit idle, you can roll the dice. We'd explore other installers with fewer catastrophic service breakdowns.
Reviews That Shaped Our Verdict
Stephanie signed up for solar hoping to wipe out a roughly $230–$300 monthly power bill for a household with two kids, and she ended up still paying those high bills on top of a $275 payment for the panels. She reached out to a salesperson named Jesse and found him unhelpful; Dominion Energy told her the array wasn’t producing the energy it should. Stressed about finances and savings for her children, she appreciated that a technician named Chris actually came out, inspected the system and offered a check for the inconvenience — but she remained worried the shortfall would continue. After logging back into her Dominion account she noticed the billing month hadn’t posted yet and the current amount was already over $160, reinforcing her fear that the promised “very small” bill hadn’t materialized. She dug into contracts and talked to people she knows who’ve had problems, and posted the review to warn would‑be buyers to do thorough research and read performance guarantees carefully before signing. Her hard lesson: verify expected production and get a clear, written plan for fixing underperformance — she plans to update the review as the situation unfolds.
Nadine hired Nexus Energy Systems/Sunternal to install solar panels and ended up in a multi-year fight over a damaged roof. She waited months for responses, had an April appointment that never got confirmed, and dealt with a rude employee on the phone — enough that she no longer wants anyone from the company working inside her house after what happened to the roof. A company specialist had cleared the roof for installation and raised no concerns, but the work that followed created new problems. After the team left, she discovered at least three leaks beneath the panels and found shards left under roof tiles that ripped the underlayment. Early on Nexus returned repeatedly — eight attempts in four months — and ultimately made 14 visits to replace broken tiles, yet the roof never got properly repaired. The roof had been inspected by Nexus in December 2022, after heavy rains had begun, but the leaks persisted. Nadine removed an earlier critical review when Chris Zettel, the COO, promised to resolve everything; six months later the situation had only worsened and she lost trust in the company. Now entering year three of the ordeal, the roof began leaking again last winter and she’s.
Laura hired Nexus Energy to install a 31-panel solar array with a SolarEdge inverter and a 9.8 kW LG Chem battery on her home in a high fire-risk area, specifically to keep the well pump plus a refrigerator and freezer running during outages. She picked Nexus because the company wasn’t the cheapest but promised reliable service, an 85% production guarantee based on her PG&E bills, a nearby sub-office, and family ownership — reasons she trusted them to size and support the system correctly. The system went in December 2019, but problems began over the following year. In August the array appeared dead; after she called customer care, two technicians arrived about ten days later and — without explaining — took the system down, leaving her uncertain when power would return. After emailing with the subject line "Unhappy Customer" on September 11, a crew returned on September 15, replaced the inverter and rewired the battery, admitting the battery had not been wired to the pump at all. That revelation mattered because the battery was meant to power the well during outages; instead the battery either failed to deliver any water or ran briefly and then stopped. Even after the September fix

Robert lived in Oceanside, CA and first turned to Nexus Energy Systems in February 2022 when he wanted a second solar array to increase the size of the rooftop system on his home. He’d been running solar for almost 17 years, so when the original converter broke down he called Nexus immediately to replace the aging equipment and consolidate the setup under their gear. He discovered the team to be knowledgeable and professional, answered all his questions, and completed the swap; today he keeps tabs on the whole system easily through the company’s app. The memorable outcome: an older system replaced quickly with a modern, app‑monitored setup that makes performance tracking effortless.
Roger B. faced high-pressure sales but accepted the company’s financing offer and had a system installed on his home. After installation he experienced repeated problems: the array kept popping breakers whenever it rained hard, and the system monitoring never got fully set up because the installer never delivered the Wi‑Fi connector box. When he pushed for a fix the company demanded $1,000 to get monitoring working again, and then he discovered a roof leak that the installer denied responsibility for. He recommends that others obtain several quotes and look elsewhere — he ended up with tripped breakers in wet weather, no functioning monitoring, a $1,000 demand to complete the setup, and a leaking roof the company would not own.
