Go with Harvest

We've only had solar for a few weeks, but so far we're very happy to have chosen Harvest Power. We wasted too much time listening to many others, but everything changed when we spoke to Harvest. Particularly, Anthony Rossano. As a sales rep, Anthony's knowledge and people skills are superior. The installation was seamless and beautifully designed. Highly recommend, Harvest Power.

Latest bad review thumbs down

Harvest Solar | Commack, New York | 11/30/2025

Stay AWAY!!!

The level of unresponsiveness from this solar company has been extremely disappointing. I have been attempting to reach them for more than six months, during which time I received nothing but repeated excuses and delays. Despite referring four potential customers who were ready to move forward with solar installations, the company failed to contact any of them. After half a year of silence, they finally reached out—only to inform me that they would not be able to complete my installation before year-end, meaning I would no longer qualify for the federal tax credit. To make matters worse, their salesperson suggested they could simply bill me this year and install the system next year in order to claim the tax credit—an approach that raised serious concerns about their business practices. Overall, my experience has been deeply unsatisfactory. I strongly advise others to proceed with caution.

Amazing Mark L

We had the pleasure of meeting Mark Lieberman. I was referred to Harvest Power by a friend who had their Solar installed by Harvest Power. Mark was the most friendliest, honest rep. He was very thorough in explaining Solar to us step by step, from start to finish. He answered each question without hesitation. He knows his stuff. He steered us in the right direction with going Solar. I hate change, but I like the way he presented himself and the pros of going Solar. There were no cons We were very comfortable with him He’s easily liked. We previously had a consultation with a rep from another company, where we were hesitant He just talked about leasing, being free and dont worry, we don’t pay anything. Down the road you’d be paying alot leasing We purchased our panels from Harvest Power and that’s the way to go, buying them outright. The first rep from the other company, didn’t volunteer much info when we asked questions. We basically had to answer our own questions and he just agreed with us He was out for his company and not for us Mark was looking out for our best interest and wasn’t at all pushy We’re very happy we signed up with Mark Lieberman. We’re so looking forward to our first months experience with going Solar with Harvest Power We highly recommend Harvest Power and our salesperson Mark Lieberman TY Mark You’re very much appreciated!!

Harvest Power Saved Me Money

I began my journey with Harvest Power in the summer of 2024, and the entire process was efficiently completed with my solar system going live by September. I deliberately waited to write this review, wanting to ensure that the results were as promising as they initially seemed—and they absolutely are! Not only did I install solar panels with Harvest Power, but I also got a new roof. I was particularly anxious during tax season, wondering if the calculated return they estimated would hold true. To my delight, it did! Experience with Harvest Power: I conducted thorough research, speaking with multiple companies and gathering numerous quotes for both solar panels and roofing. What really set Harvest Power apart was the genuine professionalism and dedication of the team members I worked with—Mark Centauro and his manager, Frank M. They were diligent, incredibly kind, and took the time to thoroughly educate me on the benefits of solar energy. Every question I had about the panels and the roof was addressed with patience and clarity. A standout moment was when Mark candidly informed me about an unethical practice in a competitor's quote, which was essentially fraudulent. His honesty and transparency reinforced my confidence in choosing Harvest Power. Additionally, whenever Mark wasn’t available, Frank seamlessly stepped in to address my concerns, ensuring I felt supported throughout the process. Performance and Results: Since the system went live in the fall, I've witnessed a dramatic reduction in my energy costs, just as promised. The tax savings were also spot-on. Based on my experience, I can recommend Harvest Power without hesitation. Room for Improvement: If I had to point out one area for improvement, it would be their mobile app. It requires an additional add-on to display real-time energy usage. To be fair, Mark wasn’t aware of this due to a recent software update, but it would have been helpful to know upfront. Final Verdict: 10/10 for Harvest Power. Thank you, Mark C., Frank M., and the entire Harvest Power team for an outstanding experience!

Review for Harvest Power LLC

I am extremely disappointed with my experience with Harvest Power LLC. They installed a solar system at my home, but it has failed to provide accurate energy reporting to PSEG Long Island. Despite numerous attempts to resolve this issue, their team has been completely unresponsive and unaccountable. After working directly with PSEG to investigate discrepancies between my electrical meter and the Enphase system readings, it was confirmed that there were no issues on PSEG’s end. This means the problem lies solely with Harvest Power’s installation and equipment. To make matters worse, the system they installed covers only 30% of my total energy consumption, far below what was promised. I feel completely misled about the efficiency and coverage of this system. I have been chasing their team for weeks with no resolution, and their lack of responsibility is unacceptable. Due to their failure to address these serious issues, I am now escalating my complaint to Enphase, the Better Business Bureau (BBB), the local consumer protection agency, and the State Attorney General’s office. If you are considering solar installation, I strongly advise against choosing Harvest Power LLC. They have shown zero accountability, and their customer service is practically nonexistent. Don't make the same mistake I did—go with a company that actually stands by its product and provides real support.

My Harvest Solar panel installation project

I rate my experience with Harvest Solar as outstanding; 5 star all the way including 5 stars for Tyler Cirincione, the Harvest Solar, representative who worked with me throughout the project. He exhibited numerous qualities that warrant special commentary given his superior performance and excellent customer service. He was honest; transparent about the various positives and negatives of different courses of action; exhibited great of knowledge about solar technology which he shared in an open informative manner; was highly responsive to my questions and concerns; appeared earnest with an authentic desire to do a great job; and finally took a complicated multi variable project with many gears and wheels and simplified it into manageable parts ferrying me through each task while being kind and, importantly, patient with me being responsive to all my needs. I thank everyone involved including the team that replaced my roof and finally the Harvest team who installed the solar panels themselves.

Frank Mirasola and his Team were very Professional!

Frank Mirasola came to my house and was patient, answered all my questions and was NOT pushy at all. He truly showed up to help. Even after the initial meeting he would answer my follow up text questions in a timely manner. That also brought me peace in moving forward with his company. His installation team was clean, quick and kind! I couldn't of asked for a better experience. Thanks Harvest Power for bringing your "A" team to my house!

I highly recommend Harvest Power and working with Frank Mirasola was great! Frank was professional, he also explained everything clearly and walked us through the steps of the solar process. He answered all of our questions, concerns, and put us at ease. There were no pressured sale pitches, just honest answers. He made my choice for a solar company easy. The whole process was easy from beginning to end.
