Complete Breakdown of Solar Incentives Long Island
Navigating clean energy incentives can feel overwhelming, but New York offers some of the most aggressive solar savings in the country. Here is how the main incentive programs work together to lower your installation costs.
TOTAL SOLAR SAVINGS STRUCTURE
| 1. NY State Tax Credit (Form IT-255) —-> Up to $5,000
| 2. NYSERDA / PSEG Battery Rebate —-> Up to $6,250
| 3. NYC / LI Property & Sales Tax exemptions –> 100% Exempt
1. New York State Solar Equipment Tax Credit
New York State offers a direct state income tax credit for residential solar installations.
- The Benefit: 25% of your total solar system cost as a direct state tax credit.
- Maximum Cap: Capped at $5,000.
- Tax Form Required: File NYS Form IT-255 alongside your annual state tax return.
- Rollover Provision: If your tax liability for the year is lower than your credit amount, you can roll over the remaining balance for up to 5 consecutive years.
2. NYSERDA & PSEG Long Island Battery Storage Rebates
If you are adding energy storage to your system (such as a Tesla Powerwall or Enphase IQ Battery), NYSERDA partners with PSEG Long Island to offer direct upfront rebates through the Battery Storage Rewards Program.
- Storage Incentive Rate: Up to $250 per kWh of usable battery capacity.
- Average System Savings: A typical 13.5 kWh home battery yields an upfront rebate of approximately $3,375, capped up to $6,250 for larger residential setups.
- How It Works: You do not have to wait for tax season to get this rebate. Your approved solar contractor deducts this amount directly from your installation invoice.
Combining battery storage rebates with available solar incentives Long Island gives homeowners the maximum return on investment
3. Sales Tax and Property Tax Exemptions
Installing a solar power system increases your home’s market value, but New York law ensures you aren’t penalized for it.
- 100% Sales Tax Exemption: Solar energy equipment purchases are completely exempt from the 4% NY State sales tax and the local 4.625% Nassau/Suffolk county sales taxes.
- 15-Year Real Property Tax Exemption: Under NYS Real Property Tax Law Section 487, the added value a solar system brings to your home is exempt from local property taxes for 15 years.
- These tax exemptions represent one of the most immediate solar incentives Long Island residents can benefit from upon installation.

IMPORTANT TIP FOR HOMEOWNERS
To qualify for NYSERDA rebates and PSEG Long Island grid incentives, your solar panels and battery storage system must be installed by an approved, participating NYSERDA contractor. DIY installations or uncertified contractors cannot access these state rebates.
How Net Metering Works with PSEG Long Island
When your solar panels generate more electricity than your home consumes during sunny afternoons, excess energy is sent back to the local utility grid.
Under PSEG Long Island’s Net Energy Metering (NEM) guidelines:
- You earn kilowatt-hour (kWh) credits for every unit of clean energy your system exports to the grid.
- During the night or during cloudy weather, your home automatically draws power from the grid using those credits.
- This process significantly lowers or entirely eliminates your monthly electric bill, leaving you responsible only for a small standard customer connection fee.
