Onsite Energy USA reviews

Maria typically doesn't write reviews, but after Onsite Energy Inc. installed a significant number of solar panels at her home more than a year ago, she felt compelled to share how it turned into one of her best financial decisions. She experienced substantial savings over the past year and credits those gains to the company's expertise and attention to detail. From planning to installation, the crew acted professionally and kept communication steady and clear, so she always knew what to expect. Even now, when questions pop up, she still gets quick, helpful responses from the team. The detail that stood out most was that ongoing responsiveness—months after the install, she can call and get answers promptly, which made the whole investment feel practical and low‑stress.

Peter and his wife had solar on their house for eight years and decided to add panels to their barn, which includes a second-floor apartment heated with radiant floors. He chose Onsite Energy again and experienced excellent, consistently responsive service both times. Work on the barn began in late December into early January 2023–2024 during steady rain, so the crew completed the electrical work on a soggy day and then the same two technicians returned after the New Year to install the panels. Project manager Victoria Slane stayed available throughout, answering questions and keeping him informed as she handled the grants-and-loans paperwork. The new arrays look attractive and now offset the family’s Central Hudson electricity usage. What stuck with him was how the team managed a winter installation and the administrative side without losing communication — the follow-through turned a potentially stressful timing and weather issue into a smooth outcome.

Sarah Colker hired Onsite Energy for a residential solar installation and, as an engineer used to projects running late, was pleasantly surprised to find the team ran like clockwork. The install itself unfolded smoothly: crews stuck to the agreed schedule, communicated clearly at every stage, and answered her questions promptly. She walked away impressed by their professionalism—what stood out most was their punctual scheduling and quick, reliable communication.

Amar Paul Singh shopped more than five solar quotes before choosing OnSite Energy and Ryon Hayman, attracted by competitive pricing and strong local reviews. He found those reviews were accurate: crews led by Jack Kusack and Gregg Villman, with Evan Pol and John Diaz on the roof, installed the system in a single long day. He watched a careful, tidy job — balanced panel placement, clean cable runs and electrical conduit that looked as deliberate as a finish carpentry detail. Owning multiple properties and rarely writing contractor reviews, he noticed the crew’s obvious pride more than anything else. The image that stuck with him was the meticulous conduit work and how neatly the panels integrated with the roof.

Jason tackled solar for his quirky 35-year-old house and, after sourcing five regional bids through EnergySage and getting a lead from his preferred mostly North American panel maker Silfab, landed on Onsite because their price was notably lower and he could deal directly with the owner, Ryon. As a retired engineer he pushed hard—his home carried wiring oddities like a remote meter/main switch and a maxed-out breaker panel—but Ryon and the crew met him halfway, repeatedly reshaping the permitting drawings so component placement fit the house. They guided his electrician through the panel upgrade, raised the inverter specification so the array could accept a few more panels in the future, and steered him toward a single inverter instead of per-panel microinverters; that change, plus a modest panel power bump they passed along, improved the dollars-per-kW math and boosted his NYSERDA rebate. Onsite also held off installation until a full reroof finished, sending a disciplined, efficient crew when the time came. Getting Orange & Rockland to grant permission to operate hit a hiccup, but Onsite pressed the issue and secured PTO on the second attempt. The Solaredge inverter dashboard

When comparing eight bids for a rooftop system on his house, pdx.jason.timm discovered that Onsite offered American-made Silfab panels at a price significantly lower than competitors using less-American-made equipment. He picked up a practical design change from Ryon, the owner: move to a single Solaredge inverter instead of per-panel inverters for stronger power handling, and size the inverter run to 7,600 W so adding panels later would be straightforward. The roof faced the sun well but the electrical setup was tricky — a remote meter/main switch and a breaker panel already at capacity. Ryon and the design team worked with him through about three rounds of permit-drawing updates as he suggested different component placements. Onsite also guided the electrician’s upgrade work, which included installing a new main switch and a back-fed breaker that optimized the house wiring for the solar tie-in. Rather than rush, the crew waited until a full reroof finished before mounting equipment; installation went in with a disciplined, efficient team. Securing permission to operate from Orange & Rockland hit a hiccup: inverter settings were correct but the utility wanted deeper technicals

When Tom Venable decided to lower his electricity bills, he hired Onsite for a solar-panel installation. He found the entire process professional from start to finish: Andrew guided the sales process, the installation crew handled the rooftop work, the electrician completed the hookup and verified that everything worked as planned, and Victoria in the main office kept the administrative side moving. Because the team coordinated cleanly and every step was helpful, he recommends Onsite to others looking to cut power costs — what lingered for him was how seamless the handoff was between sales, installers, electrician, and office support.

Henry experienced a smooth, end-to-end solar installation at his home with Onsite Energy and found everyone he dealt with to be helpful and professional. What stood out most was the genuinely attentive support he received in the months after the system went live, which kept the transition painless and reassuring. He’s already planning to refer others and is looking forward to getting more benefit as the days grow sunnier. The detail that will stick with him: the company’s dependable follow-up long after the panels were installed.

Pakkee booked a winter rooftop install and discovered the crew answered quickly and completed the work on schedule. They couldn’t run a proper performance test because short winter days and cold limited the system’s output right after installation. What stood out was the responsiveness and reliability of the team — the job was finished as promised despite the season. They suggested the company look at ways to prevent ice from sticking to panels, and left with the clear takeaway that anyone installing in winter should expect a smooth install but plan for delayed performance verification and ask about anti-icing options.
