SUNation has met all of my expectations. Our installation was back in November and we have already made use of our battery backup system. I highly recommend using SUNation!
I am very happy with the results and service they provide. Staff and crew were courteous, knowledgeable and neat. My electric bill are now very minimal per month which is the best.
There is not a better solar company out there. We were very pleased with every aspect of the process. I've recommended over 6 people to them and everyone is equally pleased. A++++
Customers will receive $500 off their solar system contract, with payment issued after system installation. Offer valid only for purchase-to-own contracts signed between 9/1/25 and 9/30/25 and cannot be combined with other promotions. SUNation clients are responsible for ongoing utility bill payments. Battery storage systems are only available for homes/buildings in PSEG-LI territory.
SUNation’s installation timeline applies to standard residential rooftop systems within its regular service areas and may be voided due to delays outside SUNation’s reasonable control, including but not limited to:
Municipal factors: Permitting delays, inspection schedules, code changes, or C.O. issues
Utility factors: Engineering reviews, upgrades, net metering/tariffs, or PTO delays
Customer factors: Delayed roof/structural work, unresolved code violations, financing issues, post-contract changes, or late responses
Supply chain issues: Shortages, backorders, transport disruptions, or force majeure
Other delays: Weather events, strikes, shutdowns, or government actions
“Substantially completed” means all major components are installed, and the system is ready to pass final inspection, even if PTO is still pending. Failure to meet these responsibilities releases SUNation from the timeline guarantee. Qualification for solar and/or storage installation depends on site conditions and other factors. Speak with your SUNation solar expert for full eligibility details.
Financing (including $0 down options) is subject to credit and lender qualifications.
Tax Disclaimer: This is not tax, legal, or accounting advice. Consult a qualified tax advisor to confirm your eligibility for any incentives.
SUNation is not liable for any loss of tax credit eligibility due to delays beyond its control.
