Solar incentives are designed to make renewable energy usage more affordable via financial incentives to help people install solar panels on their homes. The incentives could include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are provided by the federal government, some by the New York government and some by your utility company, county or municipality. Types of solar incentives might include:

  • Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.
  • Tax Exemptions: Sales tax exemptions are effective at the point of sale for your solar system. Property tax exemptions allow you to exclude the added value of your solar system when you calculate how much property tax you need to pay.
  • Net Metering: Net metering becomes relevant after your solar panels are up and running. If you have a net metering agreement with your West Islip utility company, the company will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some places, this credit is dollar-for-dollar, while in other areas you may make back a percentage of the value.
  • Rebates: Rebates, or cash back after a purchase, are usually applied prior to any solar tax credits being calculated. Solar rebates may be given by your local utility company, by your county or by your state.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that comes to mind when thinking about solar incentives. The solar incentive that you may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a certain percentage of your solar system's cost.

The ITC can be applied to solar panels installed after January 1, 2006, on a primary or secondary residence in the United States that you own. The credit initially covered 30% of the total cost – for panels, equipment, labor and accessories – although it may range from 26-30%, depending on when your solar system was installed. There is no cap on the claim amount.

Speaking with your local West Islip solar panel installation expert is the best way to learn more about how the ITC may apply to your situation.

The ITC was renewed and increased in scope after the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. The Clean Energy Credit is valid until 2035. Solar installation projects started after January 1, 2022, and completed by the end of 2032 may qualify for a 30% tax credit. The amount will then decrease slightly each year until the end of the current program. Starting in 2023, it will also be easier to get credits for energy storage systems with the new act.

State & Local Solar Incentives

Tax credits, rebates and more might be provided at multiple levels. In addition to federal solar incentives, there are often state and local ones as well. Incentives may be provided by your county or municipality, or by the state of New York. Some incentives are available for only a limited time, while others are ongoing.
