Solar Incentives for East End Homeowners in 2026

The solar incentive landscape changed dramatically in 2026. The federal 30% solar tax credit for purchased systems — which had been the backbone of residential solar economics for over a decade — expired on December 31, 2025. For East End homeowners considering solar this year, the financial picture looks different than it did in 2025. But meaningful incentives still exist, and the case for going solar in the Hamptons remains strong. Here's what's actually available in 2026.

The Federal Tax Credit — Status in 2026

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into federal law, ending the 30% residential solar tax credit (Section 25D) for systems placed in service after December 31, 2025.

What this means in practice:

• Homeowner-owned systems installed in 2026 do NOT qualify for the 30% federal credit. This includes systems purchased with cash or financed with a solar loan.
• Systems installed in 2025 can still claim the 30% credit on their 2025 tax return, due by April 15, 2026.
• One federal pathway remains: systems owned by a third party — solar leases, Power Purchase Agreements (PPAs), and prepaid solar products — still qualify under the commercial Investment Tax Credit (Section 48E) through December 31, 2027. The third-party owner claims the credit and typically passes the savings through lower monthly payments to the homeowner.

"The case for going solar in the Hamptons remains strong — the incentive stack is different, not gone."

What Still Exists — The New York State Tax Credit

New York State's residential solar tax credit is still active in 2026 and continues to be one of the most valuable in the country:

• 25% of net solar system cost (after any NYSERDA rebate is subtracted)
• Maximum credit of $5,000 per residence
• Applies to both purchased AND leased systems — unlike the former federal credit, the NY State credit works regardless of ownership structure
• 5-year carry-forward if you can't use the full credit in the first year

This is a meaningful number. On a typical East End residential installation, the NY State credit alone can reduce out-of-pocket costs by several thousand dollars.

NYSERDA NY-Sun Program — Long Island Status

NYSERDA's NY-Sun program provides upfront per-watt rebates that solar installers apply directly to your project cost — you never see the paperwork. The program operates on a regional Megawatt Block system that closes once each block fills.

As of 2026, the Long Island region's standard residential block availability varies by month and should be verified at the time of contract. The picture has tightened considerably from prior years:

• Standard-income households: Block availability depends on current NYSERDA dashboard status — your installer can verify in real time
• Low-income households (≤80% area median income): The Affordable Solar Residential Incentive remains active, providing $0.40 per watt on Long Island, capped at $20,000 per home

Your solar contractor should verify your specific eligibility and block availability before signing any contract.

New York Property Tax Exemption

Possibly the most underappreciated incentive on the East End: New York State law exempts the added value of solar installations from property tax assessment. On a property with high tax exposure — typical for Hamptons estates — this exemption can be worth tens of thousands of dollars over the life of the system.

The exemption is automatic but requires proper paperwork submission at installation. Your contractor should handle this filing as part of your project.

Net Metering and VDER

On Long Island, PSEG-LI provides net metering for residential solar — meaning you receive bill credits for excess electricity your system sends to the grid. New York is gradually transitioning to a more nuanced Value of Distributed Energy Resources (VDER) framework, but net metering remains the standard structure for new East End residential installations in 2026.

Combined with Long Island's high retail electricity rates (among the highest in the country), net metering significantly improves solar economics — independent of any tax credit.

What This Means for East End Homeowners in 2026

The 2026 solar incentive landscape is different from 2025 — but the economic case for solar on the East End remains strong. Here's why:

• NY State tax credit ($5,000 maximum) is fully available
• NY property tax exemption continues to deliver long-term value
• High Long Island electricity rates make solar self-generation valuable independent of credits
• Third-party ownership (lease/PPA) still captures federal incentive value indirectly
• NYSERDA rebates remain available for qualifying households

For purchased systems, the math is meaningfully different than in 2025. For lease and PPA arrangements, the federal incentive still flows through to the homeowner via lower payments.
