The term "solar incentives" broadly refers to financial incentives designed to encourage the adoption and use renewable energy by making solar panels more affordable. The incentives might include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are handled by the federal government, some by the New York government and some by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Rebates: A rebate is a partial refund credited to your account after you've paid for your solar panels. Rebates might be offered by your local utility company, your state or your county. The rebates are usually applied before calculating tax credits.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Tax Exemptions: Sales tax exemptions are applied at the point of sale for your solar panels. Property tax exemptions let you ignore the value that your solar panels add when you're calculating how much property tax you need to pay.
  • Net Metering: Net metering factors in once your solar system is up and running. If you have in place a net metering agreement with your Ronkonkoma utility company, it will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some locations, this credit is dollar-for-dollar, while in other places you may make back a percentage of the value.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives might be the first thing that comes to mind. The solar incentive that you're most likely to have heard of is the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a specified percentage of the cost of your solar system.

The ITC applies to the total cost of solar system installation, including the panels themselves as well as equipment, accessories and labor. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence located in the United States that you own. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum claim amount.

Talking to your local Ronkonkoma solar panel installation expert is the best way to understand how the ITC applies to your situation.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. Homeowners can now receive a 30% credit for solar systems that began installation on or after January 1, 2022, and will be done by December 31, 2032. The total credit will then decrease annually until the date of expiration. Beginning in 2023, it will also be easier to claim credits for energy storage systems under this new program.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit applies to you is to reach out to your local Ronkonkoma solar panel company with your questions.

State & Local Solar Incentives

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

EcoWatch's Ronkonkoma, NY Solar Incentives FAQs

How do I learn if I qualify for certain solar incentives?

It's a good idea to talk to your local Ronkonkoma solar installer to get an understanding of which incentives your project will qualify for. Usually, solar incentives apply to new solar panel systems installed on a property you own (in the U.S.) between the dates specified by the incentive. Some incentives, such as those offered by the government of New York, might have other requirements.

How much can I save on my electric bill annually if I install solar panels on my Ronkonkoma home?

Once you add solar panels to your Ronkonkoma home, you can expect to save approximately $1,151.18 per year, or around $21,872.41 over 20 years.

What are some environmental benefits of installing solar panels on my house?

You can decrease your carbon footprint by 500 pounds of CO2 a year when you switch to solar panels. This adds up to roughly 10,000 pounds over 20 years. Solar is also a renewable energy source, which means that switching your home over lessens the drain on our planet's resources.

If I trade in my appliances for ones that use solar energy, are there any credits I can claim?

Under the new Inflation Reduction Act, there are several new financial incentives that are available when you make eco-friendly improvements to your home. More details regarding these incentives, including information about incentives for purchasing new appliances, can be found here.
