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.

3 Stories That Stood Out

1. Nadine Schmitz
Google | Jun 30, 2023 |

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.

2. laura p.
Yelp | Jan 28, 2021 |

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

3. Stephanie Hudgins
Google | Sep 17, 2025 |

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.

What You Can Expect

1. Robert Ball
Google | Nov 17, 2024 |

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.

2. Bodiesattva23 23
Google | Jul 28, 2021 |

Bodiesattva23 decided about a year ago to do more for the planet by converting their Richmond-area home to solar. After meeting several local companies, they settled on Nexus following an initial consultation — Nexus’s technical expertise and clear knowledge set them apart from the other outfits and gave the confidence that the installer was acting in their best interest. Now they have a solar system that’s cutting their bills and shows solid, high-quality workmanship. The detail that stuck with them was that first consultation: the consultant’s competence turned a long search into a definite choice.

1. Miguel F.
Yelp | Apr 19, 2021 |

Miguel F. ended up with solar panels installed on his home two years ago but discovered they were never actually connected after a fire — and he’s been paying both PG&E bills and the panel loan ever since. The physical installation looked good, but the schedule and communication unraveled quickly: he wasn’t told that loan payments would begin once panels were installed, and a promised escalation to a manager never produced a clear solution. He chose NEXUS because a friend recommended them and because the sales consultant, Niccolus A Smith, made a strong impression. That confidence led him to refer a family friend; when that friend later asked about the company’s referral program, Miguel learned the reward never materialized beyond a single thank-you text. He reached back out to the consultant and the home office by text — the channel he finds fastest — only to be left unread for more than a week. Throughout, Miguel’s judgment split in two: the crew installed the system well, but the company failed at follow-through and billing transparency. He walked away with a clear lesson for other buyers: solar can be a solid long-term investment, but confirm in writing when panels will be,

2. David Li
Google | Sep 29, 2020 |

David Li hired the company for a residential solar installation and experienced attentive service both leading up to the install and again a year afterward. He found the team reliable throughout the process and singled out his lead installer, Alex, as exceptional — the standout who kept the job running smoothly. He walked away impressed by the company's continued follow-up a year later, with Alex's leadership being the single detail that really defined the experience.

3. Michael Becker
Google | Aug 1, 2018 |

Michael Becker had Nexus Energy Systems install a solar array on his home about a year ago. When he bought an electric car, he called them back and they came out to upgrade the system to provide extra capacity — a seamless expansion rather than a complicated retrofit. He found every part of the team — sales, project management, installers and management — consistently pleasant, quick to reply, and punctual; the work was completed on schedule and on budget. The crew walked him through each step, answered all his questions, and continued to provide support after installation. The lasting impression: Nexus didn’t just install panels and disappear — they returned to expand the system for his EV with no hassle and clear communication throughout.

1. Maribeth M.
Yelp | Nov 16, 2018 |

Maribeth met Nexus two years ago after several companies refused to install panels on her rock roof. Nexus figured out exactly how many panels she needed for her household usage and completed the installation where others wouldn't. This year Anaheim credited her account with two months of zero bills because her system stored more energy than she used — a payoff she describes as getting paid for using natural resources. She ended up with a working solar setup on a challenging roof and two months without utility charges, and she thanked Nexus for making it happen.

2. Fernando Vergara
Google | Jun 20, 2018 |

Fernando Vergara jumped into solar with almost no technical background, installing an initial system sized to cover roughly 90% of his electricity. After about a year he discovered recurring NEM charges on his PG&E bill and decided to add more panels to the existing array. The expansion flipped the picture: the system now exports a substantial amount of electricity to the grid on most days and was designed with extra capacity for future needs like charging an electric vehicle. Nexus Energy’s crew handled the installation, took time to walk him through how a microinverter setup works, and left him comfortable expanding the system. He found the installers professional and appreciated that customer support remained "just a phone call away." The detail that sticks: hands-on education about microinverters and a clear plan to scale the system as energy needs grow.

3. Chad Payne
Google | Oct 6, 2025 |

Chad Payne installed solar panels on his home and grew increasingly frustrated when promises of generation never translated into lower bills. He kept getting assurances that the system was producing power, yet his most recent electric statement still showed a $265 charge — essentially the same expense he had before the panels. He pushed for answers repeatedly and felt bounced from one promise to the next with no real troubleshooting or fixes. Customer service became a sore point: he and his wife struggled to reach anyone, and the only time they got a response was after his wife posted a public review — then the company called asking her to remove it. After giving the company multiple chances, he concluded the array was doing nothing for his bill and came away convinced the installer cared more about sales than solving the problem. The detail that sticks: a persistent $265 electric bill despite installed panels, and contact only after going public with a complaint.
