Local reality
What actually matters in Penfield
- Penfield's 1970s-90s subdivisions came with 200A services as standard, which removes the panel-upgrade change order that derails projects in the city of Rochester. It also means installers quote larger systems here by default — bring your own twelve months of kWh history rather than accepting their sizing.
- Irondequoit Creek's wooded corridor cuts diagonally through the town. Lots backing onto it carry mature canopy that a satellite roof outline will not capture.
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 Penfield 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
