Solar incentives are intended to make renewable energy usage more affordable via financial incentives for those who install solar panels on their homes. Various types of incentives, such as discounts, cash back or monthly utility bill credits, may be available to you. Certain incentives may be provided via the New York government, by your utility company or by county or municipality, while others are federal. You might qualify for any of the following types of solar incentives:

  • Net Metering: You may be able to sign a net metering contract with your Smithtown utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then deduct this value from your monthly utility bill.
  • Rebates: Your solar installer might help you claim a rebate, or partial refund after purchase, for your solar system. States or counties will also sometimes offer limited-time rebates. The value of a rebate will usually be deducted from your total price before any tax credits are calculated.
  • Tax Exemptions: Your solar panel system may qualify for both sales tax and property tax exemptions. Sales tax exemptions are effective at the time of purchase. Property tax exemptions allow you to ignore the added value of the solar panels when calculating property taxes on your house.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (A tax credit is different from a tax deduction.)

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. The Federal Solar Investment Tax Credit, or ITC, is the best-known federal solar incentive. The ITC provides you with a tax credit for a set percentage of your solar system's cost.

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

To find out exactly how much the ITC could save you, contact your local Smithtown solar panel installer.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). The Clean Energy Credit re-raises the credit up to 30% for solar installations undertaken between January 1, 2022, and December 31, 2032. After 2032, the credit percentage will be reduced slightly each year until the end of the program in 2035. The expansion also makes claiming credit for energy storage systems easier than ever before, starting in 2023.

State & Local Solar Incentives

There are often also state solar incentives in addition to those provided by the federal government. Tax credits, rebates and more may be available at a more local level. These incentives may be distributed by your county or municipality, or by the New York government. Some incentives may be ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Smithtown

The nationwide use of solar energy has gone up significantly in the past 15 years, in part due to the proliferation of solar incentives. You might receive these incentives from your local utility company, the federal government or the New York government.

On average, Smithtown homeowners who install solar panels save around $1,151.18 per year, or about $21,872.41 over 20 years after they make the switch.

Can I claim incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can claim both rebates and tax credits towards the cost of your solar panels. Depending on precisely which incentives you are applying for, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to ensure that you are claiming the correct incentives and that you're getting the most money possible.

Can I use multiple types of renewable energy to power my home?

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Be sure to talk through your ideas with your local Smithtown solar installation expert. They can help you with the plan for your project and also help you understand the various incentives that you might or might not qualify for.

Can I receive any incentives when I add solar panels to a vacation home, rental property or commercial property?

Many solar incentives apply to a property located within the United States that you own; most secondary residences fall under this distinction. There may be other solar incentives available for commercial properties, depending on the details. We recommend talking to your local solar installer and/or tax professional to best understand what incentives will apply to your specific situation.
