The company provides its customers with great warranties, but as of now, it only services a few areas in New York. If you live in one of those areas, SUNation Energy may be a good option for you. However, if you live elsewhere, you'll need to check out other solar companies.

JC. The Bronx, NY

They really promised alot and failed to keep their word and promise in multiple aspects I really dont recommend anyone go solar because it not worth getting in debt and having a system that does not function as promised and have damage done to your roof. The first person I spoke to pauline promised a solar panel instalation with a tesla battery I started the paper work and a few months went by then they changed Pauline as my rep to James he scheduled my instalation and I did not receive a tesla power bank with my instalation he told me that there must have Been a confusion cause they do not normally include them in their installs. I was promised 120 percent of my homes power production but the systems has never produced that much power for me it doing a little more than 70 percent so my I still pay around 60 dollars of electricity on top of the solar panels. They told me I would get exactly 12700 dollars of tax reimbursement so that I can pay off half of the instalation I got about 7000 and now have have to pay the difference on top of the 15 year loan. That 5,700 that I have to immediately pay back so there really is no saving as expected and the 0 money out of pocket cost is a lie. They told me that if my ceiling ever had a leak that I would need to call right away and that they would send some one immediately. Today my roof started leaking and they told me the soonest they would have some one out here would be a week. Both of my reps Pauline and James no longer work at sun Nation I have no one to go to for assistance and their service is piss poor I am really not happy with the desicion I made with this company to go solar.
