Solar incentives are designed to make renewable energy usage more affordable through financial incentives for individuals who install solar panels on their homes. Incentives can include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered by the federal government, while others are handled by the state of New Jersey or your specific utility company, county or municipality. Categories of solar incentives include:

  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the government.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar panels. Counties or states will also offer limited-time rebates at various times. Any rebates you receive will usually come off the total price before tax credits are calculated.
  • Tax Exemptions: Tax exemptions may come in two forms. The first is sales tax exemption, which is applied when you purchase solar panels. The second is property tax exemption, which allows you to ignore the added value of your solar system when calculating property tax for your house.
  • Solar Renewable Energy Certificate (SREC): In general, solar systems that produce over a specific (usually small) amount of electricity will qualify for SRECs or similar performance-based incentives. SRECs and the like are typically offered at the state level. SRECs can be sold to your utility company or another buyer, and this is usually considered part of your taxable income.
  • Net Metering: You can sign a net metering contract with your Princeton utility company that will apply to all or a percentage of the excess electricity your solar panels generate. They will then subtract this value from your monthly utility bill.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives are likely the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is likely the most commonly known federal solar incentive. The ITC provides you with a tax credit for a set percentage of your solar system's cost.

The ITC can be applied to the total cost of solar panel installation, including the panels themselves as well as equipment, labor and accessories. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence that you own, as long as it is located in the United States. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum amount you can claim.

Your local Princeton solar panel installation expert can offer more information about the ITC and how it may apply to your situation.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). Homeowners are now eligible for a credit equal to 30% of the total solar system installation costs for projects started after January 1, 2022, and completed before the end of 2032. The percentage will then decrease on a yearly basis until the Clean Energy Credit expires in 2035. The expansion also makes it easier to get credit for energy storage systems, starting in 2023.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these can include tax credits, rebates and more. Certain incentives are ongoing, while others are only available for a limited time. They may be provided by the New Jersey government, or by your county or municipality.
