Suffolk County is the largest county in New York by area and one of the most active solar markets. PSEG Long Island rates of $0.22–$0.28/kWh, large suburban lots with unobstructed roof planes, and the full NY incentive stack drive a robust market. Eastern Suffolk (Hamptons area) also sees significant solar adoption for energy independence.

Primary utility: PSEG Long Island — eligible for NY-Sun Megawatt Block and net metering. Average monthly bills: $175–$230/month. Typical payback: 5–9 years.
New York offers a 25% state income tax credit on solar installation costs, up to $5,000. This stacks on top of the federal 30% ITC. Combined, Suffolk County homeowners can offset up to $14,000+ in tax liability depending on system size.
NYSERDA's NY-Sun program provides upfront per-watt rebates to reduce system costs. Incentive levels decrease as blocks fill — earlier is better. Your installer applies on your behalf.
Excess solar production earns credits on your PSEG Long Island bill at the retail rate, rolling month-to-month. Your installer handles the interconnection application.
Gross cost: $21,000–$36,000. After 30% federal ITC + NY 25% credit: approximately $11,700–$21,200 net cost, before NY-Sun incentives.
