Why "solar panel cost" is the wrong question
Most homeowners ask "what do solar panels cost on Long Island?" The honest answer is that the number on the proposal depends on six things: roof size, panel count, panel and inverter choice, whether you add battery backup, financing, and which incentives you apply.
A good Long Island solar quote walks through each of those line items in writing.
The cost stack on a real Long Island solar quote
Equipment: panels, inverters, racking, monitoring, battery (optional), EV charger (optional).
Labor: install, electrical, roof work, post-install commissioning.
Soft costs: permits, PSEG Long Island interconnection, inspections, sales tax.
Incentives applied: New York State 25% residential solar equipment credit (capped at $5,000), PSEG Long Island net metering, NYSERDA Long Island solar + storage incentive (where eligible), plus any active federal residential incentive verified at the time of install.
How financing changes the math
Cash typically has the cleanest math because you capture the New York State 25% solar credit yourself (and any active federal credit if you qualify). Solar loans are common and often work — but only if you understand the dealer fee and how state and federal credits interact with the loan reamortization clause. Leases and PPAs transfer the tax credits to the leasing company, which sometimes still works for homeowners but often does not.
