Harvest Power Solar reviews

The Verdict
Harvest Power has a customer service problem that should make you think twice. One homeowner was promised a system that would cover 100% of his electric bill, called the company 30 to 40 times over months to complain about underperformance, and never heard back from management. Another was told midproject that her entire roof decking needed replacing, thousands of dollars she hadn't budgeted for, then discovered two years later that the system wasn't producing enough energy to meet her original needs. When she reminded them of their promise to add panels if output fell short, the company cycled through excuses instead of solutions. We found 46 reviews describing broken promises, systems that underperform vs. the estimate, and follow-up that vanishes once installation wraps. Reviewers mention poor post-installation support 38 times, and 36 flag value concerns, often because they're stuck paying both a solar loan and a utility bill. The sales reps (John Merkent, Mark Rossini, Kevin Goldstein) do earn consistent praise for being responsive and personable before the deal closes. But 343 mentions of strong sales conduct can't offset a pattern of unmet commitments and radio silence when things go sideways.
If you're comfortable chasing the company for months when your system underdelivers, you might tolerate the risk. But if you expect a contractor to honor production promises and answer the phone after install day, keep looking.
3 Stories That Stood Out
Fadi met the salesperson in 2018 to size a system for his home and asked whether his roof could cover roughly 13,000 kWh of annual use. The salesperson assured him it would, and the contract promised about 11,000 kWh per year—despite more than three other companies telling him a rooftop system would likely reach only around 80% of his load. After installation he discovered the system never covers his consumption: production tops out near 10,000 kWh a year, well below both his needs and the figure written into the agreement. He spent months trying to get answers, placing roughly 30–40 calls with no meaningful response from sales, customer service, or management. A manager finally called on January 19th and promised to involve engineering and reply within 48 hours; months later the promised follow-up never came and text messages went unanswered. Left paying both his regular electric bills and the solar payments, he concluded the company had overpromised and walked away feeling ignored. When the company later returned with corrective offers, those attempts to fix the shortfall felt inconsistent and unreliable. A sales manager framed new-panel offers as a fresh-customer deal: Fadi,
Ryan Bonner signed up for a late‑2019 rooftop solar install that was pitched to cover his entire household load plus the future addition of an air conditioner in his daughter’s room — the company assured him the system would push his PSEG bills down to roughly $13 a month. He met with salesman John and was told the roof needed replacement and maybe a few decking boards; on installation day he discovered the crew had stripped the roof down to the decking and was then told the entire decking needed replacement, which would add thousands. Harvest reduced the plywood cost per panel, so he accepted the extra work to move the project forward. The real problem, though, has been production. Two and a half years on — and with no new air conditioner installed — the array still underproduces against his unchanged, long‑term work‑from‑home usage. About a year ago Harvest committed to add panels if production hadn’t improved by 2022, and he expected the company to cover that remedy; when he reached back out in January he encountered a string of excuses instead of action. The lasting impression: Harvest reduced the immediate out‑of‑pocket roofing charge but never delivered the guaranteed level
Anthony Maceroni spent a year living with a residential solar install that never matched the promises. He discovered the signed price rose by a few thousand dollars before installation, forcing a second credit pull so the company could use a different bank after giving an inaccurate estimate. After the panels went up he found the wrong meter had been installed, so the system registered zero generation for a stretch. It then took months for the company to send app access, and when monitoring finally arrived the array produced far less than the sales numbers had projected—either the home's consumption or the panels' output (or both) had been miscalculated. Now he carries a solar loan while still getting PSEG bills; the shortfall has turned the system into a negative ROI, and with panel degradation over time he doesn’t expect to ever recoup the investment. The detail that sticks: he’s paying for a system that once produced nothing on the meter and still fails to offset his utility costs.

What You Can Expect
Joann Ganly had Harvest Power put solar on her home 15 years ago. When she recently added a heat pump and found she needed more capacity, Mark Lieberman coordinated a quick upgrade: the crew dismantled and removed the old array and had the new system up and running within two weeks. The detail that stands out is that Harvest handled the full teardown and replacement on a two-week timeline.
Ernest Demuth had Harvest Power install a residential solar system in 2016. John Merkent guided the whole process, explaining each step and walking him through the details. Over the following seven years, whenever something went wrong John and Harvest Power stepped in and handled it quickly. The most striking outcome: he hasn't received an electric bill since the system started. When friends ask about his experience, he highlights the zero electric bill and John’s steady responsiveness as the reasons he points them to Harvest Power.
Fattail had their roof replaced and solar panels installed about 18 months ago, and from the outset Mark stayed helpful and quick to respond. They ended up with a solid installation and have been pleased with the build quality over time. Most notable: the system’s actual energy output has tracked the initial estimates closely, so the performance they were promised proved reliable through the first year and a half.
Mario had a rooftop solar system installed on his ranch-style home in 2019 and found the whole installation process handled smoothly by Jeff Homire and Harvest Power. Jeff guided him from start to finish, and although weather forced a few sensible delays — he even joked about not drilling into a wet roof — the team kept the timeline sensible. Over the next 3½ years a handful of minor issues cropped up; each time Jeff and Harvest Power quickly diagnosed the problem and fixed it, leaving the system running reliably. The detail that stood out most was the fast, consistent follow-up: he always got prompt attention and resolution when something went wrong.
Debbie chose Harvest Power for a rooftop solar installation largely because of the company’s reputation and because their sales rep, Kevin Goldstein, stood out as far more responsive, knowledgeable and personable than the other companies she interviewed. She found his customer care—both before the sale and long after—to be exceptional: Kevin kept answering questions, followed up unprompted about system performance, and remained available nearly two years after installation. He made the whole process feel easy and seamless, even spending a couple of hours at her house personally overseeing the installation. The detail that stuck with her was Kevin’s ongoing, unprompted follow-up well after the panels went live—the kind of hands-on continuity that made the experience feel like more than a single transaction.
Mike Giangrasso teamed up with Harvest Power and installer Jeff Homire to size a solar system for his home and carry out the installation. The team dug into his household’s energy needs, chose the right configuration, and finished the work smoothly. Five years after activation he’s watched his energy bills stay flat — no increases at all — which became the single most notable outcome of the project.
Victor bought solar panels from Jeff Homire and has stayed with Harvest Power for eight years. He found Jeff remained personally involved—checking in and answering questions long after the install—and the company’s service team jumped on any equipment issues, working diligently until things were fixed. Over nearly a decade he experienced honest, fair treatment and reliable follow-up; what stuck with him most was the combination of Jeff’s ongoing contact and a service crew that actually resolves problems.
Martin Bailey credits Jeff Homier at Harvest Power with installing a solar system that has eliminated his PSEG electricity bills for the past two years. He only pays the mandatory $14 monthly connection fee now. After watching the panels perform, he keeps directing neighbors to Jeff. His memorable takeaway: "Solar works" — see Jeff Homier at Harvest Power.
Vasanthi had a full solar system put on a new roof four years ago. About a year ago, heavy rain exposed a problem: water started leaking through and flooded her ceiling. She tried to reach the installer repeatedly—called several times, left messages and emails—but got no response. Frustrated, she hired an independent contractor (identified as a dollar tec) to inspect and repair the roof. He walked her through what he found: the panels had been mounted without proper brackets or flashing, and fasteners had been driven straight into the roof, splitting shingles and even the plywood decking. She supplied photos of the split shingles and damaged plywood, and ended up paying for the roof repair herself after the original installer failed to respond.
