Frank and his team is the best

I first met with Frank from Harvest Power about 2 months before the installation. He told me that by 6/15, I would have my solar panels installed. Indeed, by 6/15 my solar panels were installed. The office staff took care of everything. After the installation Frank continued and ongoing support and conversations to make sure everything was up to my expectations.

Jim | Sound Beach, New York | 07/10/2024

Horrible company

PLEASE BEWARE OF THIS COMPANY...Salesmen/women will cohearse you into signing..but if you change your mind they will threaten you and COME AFTER YOU FOR FEES AND MONEY. This is an unscrupulous and utterly horrible company with bad business practices. Please BE AWARE..HARVEST POWER IS THE WORST! After reading other reviews..they have damaged things and months later..they aren't fixed. I wish there was an option for ZERO STARS!!!

Reap the benefits of Harvest Power

Harvest Power and specifically Lenney Peters did an excellent job of making us feel comfortable with every step of the solar panel installation process. At the no-pressure sit-down meeting, all of the options were presented, with Lenney understanding our requests and needs and respecting them. Let me emphasize this point as this was a key piece in our decision making when shopping among solar companies. Where other companies were a bit patronizing, were trying to hand-hold, or even apply pressure, Harvest and Lenney understood that we knew what we were doing and had reverence that we had done a bit of research in advance. Another benefit of working with Harvest is that they also specialize in roofing, so the customer does not have to shop around for another, outside party in the event that one's roof does not meet the proper standards. We had gotten feedback about our roof from other parties, as well, so we knew the sales approach was genuine and sincere. It was reassuring that Harvest took care of everything, including the paperwork filing and all of the communications elements. Lenney personally makes himself available quite often and is passionate about his line of work. When he says we can reach out to him with any questions, I honestly believe we truly could, years later, and still receive the same level of care.

Highly recommend

Excellent, very professional and at a very affordable price using top of the line equipment. Paperwork and permits were done extremely fast. Mark Lieberman was experienced, honest and a total pleasure as was the entire installation crew. The panels and inverter were installed properly and neatly. The system works perfectly and we couldn’t be more pleased.

John Merkent and Harvest Power are awesome!

Harvest installed our solar system last year and we've now enjoyed a full year of zero charges for electricity. It all started with John Merkent who sat with us, crunched the numbers and walked us through the cost savings and process. The installation took one day and went smoothly. Everything John Merkent told us would happen, including the savings we would realize, happened just as he said. Thank you John and Harvest Power!
