Solar incentives are intended to make renewable energy usage more affordable through financial incentives to help people install solar panels on their homes. Incentives could include things like discounts, cash back or credit on your utility bill each month. Some incentives are provided by the federal government, while others are offered by the state of New York or by your utility company, county or municipality. Types of solar incentives might include:

  • Net Metering: Be sure to talk with your Lake Ronkonkoma utility company about signing a net metering contract. This will allow you to get a credit towards your utility bill every month for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: These might come in the form of property tax exemptions, which would allow you to ignore the value of your solar system when paying property tax on your home. You may also qualify for an exemption on sales tax at the time of purchase.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the amount of income tax you owe the federal government. These are different from tax deductions.
  • Rebates: Rebates, or partial refunds after a purchase, are typically applied prior to any solar tax credits being calculated. Solar rebates can be provided by your local utility company, by your state or by your county.

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. An incentive that most people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a given 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 panels have to have been installed after January 1, 2006, on a property owned by you for you to claim the credit. The ITC initially covered 30% of all system installation costs (panels, equipment, accessories and labor), although the total amount has fluctuated over the years between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the claim amount.

Your local Lake Ronkonkoma solar panel installation expert can provide more information about the ITC and how it applies to your situation.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now dubbed the Clean Energy Credit. The new Clean Energy Credit is valid until 2035. You are now eligible for a 30% credit for solar systems installed between January 1, 2022, and December 31, 2032. This credit will then decrease annually until its expiration. The program expansion also makes credits for energy storage systems even easier to claim, beginning in 2023.

State & Local Solar Incentives

Not all solar incentives are federal; rebates, tax credits and more might also be offered at the state and local level. Certain incentives are ongoing, while others may only be available for a limited time. They might be provided by your county or municipality, or by the New York government.

Reaching out to the company that installed your system, or any local Lake Ronkonkoma solar installer, can help you understand what incentives you might want to apply for.
