Decision brief
What changes the decision in New York
These state-specific checks are not included in a generic national quote. Resolve them before comparing payback claims. Supporting rules and official references are collected at the end of this page.
- 01Before you sign
Do not apply VDER to every residential roof
Project size and class determine whether net metering or Value Stack rules apply. Ask the installer to name the utility tariff and compensation pathway.
- 02Before you sign
Check local property-tax participation
Section 487 permits local opt-outs and local administration. Confirm the county, city, town, village, and school-district treatment with the assessor.
- 03Before you sign
Separate the state tax credit from federal assumptions
The New York credit is 25% of qualified expenditures up to $5,000 and has its own eligibility and carryforward rules. It is not the expired federal Section 25D credit.
Verified state policy
What can reduce your cost in New York
Review these 4 statewide or utility-level policy signals before comparing net cost. They are not automatically applied because eligibility, tax liability, utility territory, equipment, and program capacity can change.
Policy configuration verified .
Policy sources- Solar Energy System Equipment Credit
25% up to $5,000
The nonrefundable personal income-tax credit covers 25% of qualified expenditures, capped at $5,000, with unused credit eligible for carryover up to five years.
- NY-Sun installation incentive
Varies by region and open block
NY-Sun cash incentives are capacity-block based rather than one statewide dollar amount. The contractor must confirm the live regional dashboard before quoting the incentive.
- Residential solar sales-tax exemption

Model notes and limitationsSources and scope
Production baseline
NLR PVWatts v8 modeled a 1 kW array at 20° tilt and 180° azimuth for New York, NY 10001, USA.
Energy valuation
Self-consumed production offsets the retail rate. Production above annual use is valued at the configured export rate; utility tariffs may use different timing or settlement rules.
Not included
Roof shading, structural conditions, hourly tariffs, financing, maintenance, incentives, and tax eligibility require separate verification.
