What residential solar costs on Long Island in 2026
A typical 8 kW residential system across Huntington and the rest of the north shore runs $24,000–$28,000 before incentives. The 30% federal Investment Tax Credit drops that to roughly $17,000–$20,000. NY State's residential solar tax credit (25%, capped at $5,000) drops it further to $12,000–$15,000 net out-of-pocket. NYSERDA's NY-Sun rebate then refunds an additional per-watt amount tied to your installer's queue.
Most Long Island homeowners are paid back in 5 to 7 years on current LIPA rates — and rates have risen 4–6% annually for the last decade. After payback, every kWh the panels produce is essentially free electricity for the remaining 18–20 years of the 25-year panel warranty.
What a residential solar install includes
A residential install covers site assessment + shade analysis, a panel layout designed for the specific roof, the permit pulls + PSEG interconnection paperwork, panels with a 25-year power-output warranty, inverters with 10–25 year warranties depending on model, and a workmanship + roof-penetration warranty.
Why Huntington-area homes are strong candidates
The north shore of Suffolk gets roughly 4.3 average peak sun-hours per day — solid for the latitude. Most homes have either south-, west-, or east-facing roof planes that produce 80–100% of optimal output. Heavy shade is the main blocker, and it is worth assessing on site before any contract is signed.
Huntington and surrounding towns are also covered by PSEG Long Island net-metering — every kWh you push back to the grid offsets a kWh you pull from it 1:1, so right-sizing the system to your actual usage matters more than maxing roof real estate.
