Solar incentives are meant to encourage people to switch their home over to renewable energy by providing financial incentives that lower the burden of solar panel installation and use. Incentives might include things like discounts, cash back or monthly utility bill credits. Some incentives are offered by the federal government, while others are offered by the state of New York or your utility company, county or municipality. Types of solar incentives might include:

  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the federal government. (A tax credit is different from a tax deduction.)
  • Rebates: Rebates, or cash back after a purchase, are normally applied before any solar tax credits are calculated. Solar rebates might be given by your local utility company, by your county or by your state.
  • Net Metering: Be sure to speak with your Ontario utility company about signing a net metering contract. This allows you to receive credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Sales tax exemptions are applied at the point of sale for your solar panels. Property tax exemptions allow you to ignore the value that your solar panels add when calculating the amount of property tax you need to pay on your house.

Federal Solar Incentives

When you think about solar incentives, you likely think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is probably the most well-known federal solar incentive. The ITC allows you to claim a tax credit for a predetermined percentage of your solar system's cost.

The ITC can be applied to solar panels installed on your primary or secondary residence in the United States. The solar system has to have been installed on a property you own after January 1, 2006, for you to claim the credit. Originally, the ITC covered 30% of all system costs (panels, labor, accessories and equipment), although this amount has fluctuated over the last few years between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the amount you can claim.

To understand exactly how much money the ITC could save you, speak with your local Ontario 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 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 on a yearly basis 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

There are more than just federal solar incentives; rebates, tax credits and more may be offered at the state and local level. Some incentives are ongoing, while others are offered for only a limited time. Your local solar incentives might come from the New York government, or from your specific county or municipality.

EcoWatch's Ontario, NY Solar Incentives FAQs

I already have solar panels. Do I qualify for any incentives?

An excellent idea would be to talk to someone from the company that installed your system – or reach out to a local Ontario solar installer — to better understand which incentives you may qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are some environmental benefits of adding solar panels to my house?

You can decrease your carbon footprint by 100 pounds of CO2 a year by installing solar panels. This adds up to roughly 2,000 pounds in 20 years. Solar is also a renewable energy source, which means that making the switch lessens the drain on our planet's resources.

Can I apply for incentives both towards the up-front 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 which incentives you are receiving, they may apply in a different order. Make sure that you speak with your solar installer or a local tax professional to ensure that you are claiming incentives correctly and getting the most money possible.

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

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Be sure to go over your ideas with your local Ontario solar installer. They can help you plan your project and also help you understand the various incentives that you will or won't qualify for.
