They are essentially paying you to make your home more efficient. In 2026, we are seeing some of the highest local rebates yet:Heat Pump Water Heaters: PSEG currently offers up to a $1,200 mail-in rebate for switching from a traditional electric or oil water heater to a high-efficiency heat pump model.Smart Thermostats: You can receive an $85 rebate (plus an annual $25 "Smart Savers" bonus) just for installing an ENERGY STAR® certified thermostat like a Nest or Ecobee.Whole-Home Heat Pumps: Through the NYS Clean Heat Program, PSEG Long Island customers can receive thousands in "instant rebates" deducted directly from their invoice by a participating contractor like Powerhouse.3. The "Triple Stack": How to Save 40-50%The real magic happens when you combine (or "stack") these three layers of savings.UpgradeGross Cost (Est.)PSEG RebateFederal Tax CreditYour Net CostHeat Pump Water Heater$3,500-$1,200-$700 (30%)$1,600Whole-Home Solar$25,000--$7,500 (30%)$17,500By the time you add New York State’s 25% Solar Tax Credit (capped at $5,000), many Long Island homeowners find that the government and the utility company are paying for nearly half of their total investment.

If you’ve been waiting for the “right time” to go solar on Long Island, 2026 is officially that year. New York State has recently updated its tax laws, making renewable energy more affordable for homeowners in Nassau and Suffolk counties than ever before.

At Power House Home Energy, we want to make sure you aren’t leaving money on the table. Here are the three major incentives currently available that can slash the cost of your installation.

1. The New York State Solar Tax Credit Increase

The biggest news for 2026 is the expansion of the New York State Solar Energy System Equipment Credit.

 

  • The Benefit: For systems placed in service starting January 1, 2026, the maximum tax credit has been increased from $5,000 to $10,000.

     

  • Why it matters: This is a 26% tax credit on your qualified expenditures. For the first time, if you meet certain income requirements, this credit is now refundable, meaning if the credit is worth more than what you owe in taxes, the state sends you the difference as a check.

     

2. PSEG Long Island & NYSERDA Rebates

Beyond tax credits, there are direct “up-front” incentives that lower the sticker price of your system before you even pay a dime.

  • NY-Sun Megawatt Block: This program provides a dollar-per-watt rebate (currently around $0.40/W for the Long Island region).

     

  • The “Stackable” Advantage: These rebates are applied directly by Power House, meaning you don’t have to wait until tax season to see the savings.

3. Federal Clean Energy Credit (ITC)

The Federal government still offers a massive 30% Solar Investment Tax Credit. When you combine this with the New York State credit, many Long Island homeowners are seeing nearly 50% to 60% of their total system cost covered by state and federal incentives.

 

Is Your Home a Candidate?

Not every roof is a perfect fit for solar, but with the 2026 incentives, even “partial sun” homes are now seeing a faster Return on Investment (ROI).

What we look for:

  • Roof Condition: Since we specialize in both roofing and solar, we ensure your roof can handle the 25-year lifespan of the panels.

  • Shade Profile: We use precision mapping to calculate exactly how much power your specific roof will generate.

  • Energy Usage: We look at your PSEG bill to size a system that wipes out your monthly payment entirely.
