Is There a National Grid Solar Rebate in New York?

The short answer is no: National Grid does not pay a rebate for installing solar in New York. The per-watt incentive homeowners have seen on solar quotes comes from somewhere else entirely, and as of September 2026 it has no open block for homes.

Where the incentive comes from

NYSERDA, through NY-Sun. When a residential block is open, it is paid to your contractor and appears as a reduction in the price you are quoted, not as a payment to you. The amount depends on system size and region, and it steps down as each capacity block fills — the megawatt-block structure exists specifically to phase the incentive out as the market matures. In National Grid’s upstate territory the last standard residential block (block 14, $0.15 per watt) closed on 17 December 2025. As of September 2026 NYSERDA has no open NY-Sun block for homes in any utility territory; check NYSERDA’s NY-Sun dashboard for a new one.

The confusion is understandable. Quotes used to show a NY-Sun discount, you knew an incentive existed, and the utility is the energy company you have a relationship with. But National Grid’s role is the wires, not the subsidy.

What National Grid does do

Net metering. Exports credited at the full retail rate, held for 20 years from interconnection. The summer surplus banks as a credit balance and pays for the winter — which matters more upstate than anywhere, because the winter deficit is deeper here.

Interconnection. The application, the screening, the meter exchange and permission to operate.

And what it charges

The Customer Benefit Contribution, a monthly charge on the DC size of your system for anyone interconnecting on or after 1 January 2022. National Grid’s 2026 residential rate is $0.97 per kW-month, the lowest of the major New York utilities — about $93 a year on an 8 kW system. Billed on capacity regardless of production, and recalculated annually rather than fixed.

Being on National Grid is, on this one measure, the best position in the state. It is still a line on your bill that was not there before.

What an upstate homeowner can actually claim in 2026

• NY-Sun: $0 for now. As of September 2026 NYSERDA has no open NY-Sun block for homes in any utility territory; check NYSERDA’s NY-Sun dashboard for a new one. When a block is open, it reaches you through your contractor as a price reduction.
• New York’s 25% tax credit, capped at $5,000, on Form IT-255 for your principal residence. Non-refundable but carried forward five years — which matters if your tax liability is modest — and available on leases and PPAs of ten years or more as well as purchases.
• Affordable Solar, NYSERDA’s incentive for households with income under 80% of the area or state median income (whichever is higher), is closed upstate as well: the upstate round ran from 18 December 2025 to 9 March 2026, and no residential block of any kind is open as of September 2026.
• State sales tax exemption on residential solar equipment, with localities able to exempt their share separately.
• RPTL 487, a 15-year property tax exemption on the added value — where your municipality has not opted out. Your town, the county and the school district each decide for their own levy. It is not automatic: file form RP-487 with your assessor by the taxable status date.

And the one that has gone: the 30% federal residential credit. Section 25D was terminated for expenditures made after 31 December 2025, with the expenditure treated as made when the original installation is completed rather than when the system is placed in service. A system finished in December 2025 still qualifies even if National Grid granted permission to operate in 2026. A purchase today does not, and a quote showing a 30% federal line is overstating the net cost by thousands.

How to read the quote

Insist on three separate numbers:

1. The gross installed price.
2. The NY-Sun incentive as its own line, with the capacity block it is quoted against named. With no residential block open as of September 2026, that line should read $0 unless the installer can show you a newly opened block on NYSERDA’s dashboard.
3. The net price you pay.

The state tax credit is separate again, and it arrives when you file your return rather than at installation. If a financing schedule assumes a lump sum in year one, ask exactly which credit it means and when the money actually appears — a great many solar loan models were built around a federal credit that no longer exists.

Frequently Asked Questions

Does National Grid give a rebate for solar panels?

No. National Grid provides net metering and the interconnection process. The per-watt incentive seen on solar quotes comes from NYSERDA through NY-Sun, paid to the contractor as a price reduction, and as of September 2026 NYSERDA has no open NY-Sun block for homes in any utility territory.

What is the National Grid solar charge?

The Customer Benefit Contribution at $0.97 per kW-month of DC system size for 2026 — the lowest of the major New York utilities, about $93 a year on an 8 kW system. It is billed on capacity regardless of production and recalculated annually.

What incentives can an upstate New York homeowner claim in 2026?

New York's 25% credit capped at $5,000 on Form IT-255, the state sales tax exemption, and RPTL 487's property tax exemption where the municipality has not opted out, claimed by filing form RP-487 with the assessor by the taxable status date. NY-Sun and NYSERDA's Affordable Solar incentive have no open block for homes as of September 2026.

Why does my solar loan schedule show a large payment in year one?

Many solar loan models were built to be re-amortised after a lump-sum federal tax credit payment. That credit no longer exists for residential buyers, so ask exactly which credit the schedule assumes and what the payment becomes if it never arrives.
