Terms and Conditions

Customers will receive $1,000 off their solar system contract, with payment issued after system installation. Offer valid only for contracts signed by 11/1/25 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.
