Local reality
What actually matters in Huntington
- Best solar resource in New York State — roughly 15% more annual production per kW than a Buffalo roof.
- The most saturated installer market in the state. Quote-to-quote spread on identical hardware is the widest anywhere in New York, which means shopping is worth more here than anywhere else.
- North Shore tree cover is heavier than most people expect for Long Island, and it is the main production constraint away from the water.
The 30% federal solar tax credit is gone for direct purchases.
Section 25D — the Residential Clean Energy Credit — terminated for expenditures after December 31, 2025 under Public Law 119-21. If you did not have a system installed and operational by the end of 2025, it is not available to you. Signing a contract or paying a deposit in 2025 was not enough.
Third-party ownership (a lease or a PPA) can still access the 48E business credit through the statutory window, but that credit is claimed by the system owner, not by you. Whether any of it reaches your monthly payment is a question for the contract, not the brochure.
New York's own credit is unaffected: Form IT-255 still gives 25% of qualified solar equipment cost, capped at $5,000 lifetime, with a five-year carryforward.
If a proposal for a Huntington address still shows a 30% federal credit, ask the salesperson to point you to the IRS guidance that allows it. There is not any. Current program status →

How this page is built
This is a generated page: the structure is shared across locations, the numbers are not. Every figure comes from the source cited beside it, with the date we last checked it. Nothing here is a quote, an appraisal, or tax advice, and none of it is specific to your roof.
Rates and incentive programs change. We re-verify utility tariffs and NYSERDA program status on a rolling schedule and stamp the date on each number rather than on the page, so you can see which specific figures are fresh. Full methodology · Program status tracker · About the Local Energy Playbook
