Solar incentives are meant to help mitigate the cost of installing a solar panel system on your home. These financial incentives are intended to encourage more people to switch to renewable energy. Solar incentives can include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are handled by the federal government, some by the New Jersey government and some by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Credits: Tax credits lower, dollar-for-dollar, the total amount of tax you owe the government. Tax credits are different from tax deductions.
  • Rebates: Rebates, or cash back after a purchase, are normally given before any solar tax credits are calculated. Rebates can be given by your local utility company, by your county or by your state.
  • Tax Exemptions: These can come in the form of property tax exemptions, which would allow you to ignore the value added by your solar panels when paying property tax on your house. They may also include exemptions on sales tax at the time of purchase.
  • Solar Renewable Energy Certificate (SREC): SRECs are credits that can be sold to your utility company (or other buyers) for cash that normally counts as part of your taxable income. Generally, a certain (small) threshold of energy production must be met before your solar system is eligible for SRECs or similar performance-based incentives. SRECs and similar incentives are typically handled at the state level.
  • Net Metering: Net metering is an incentive you can get once your solar system is up and running. If you have in place a net metering agreement with your Princeton utility company, it will subtract the value of the excess energy your solar system produces from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in other areas you might receive a refund equivalent to a percentage of the value.

Federal Solar Incentives

When people think of 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 provide you with 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 called the Clean Energy Credit. Now, solar installation projects that are completed between 2022 and 2032, may be eligible for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. Starting in 2023, the program expansion will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. Your local Princeton solar panel installers are the best people to answer your questions about the new Clean Energy Credit and how it may apply to you.

State & Local Solar Incentives

There are often also state solar incentives in addition to those provided by the federal government. Rebates, tax credits and more may be available at a more local level. These solar incentives — which may be provided by the state of New Jersey, or by your county or municipality — may be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Princeton

The nationwide use of solar energy has significantly increased 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 New Jersey government or the federal government. If you're ready to make the change to solar energy, talking to your local Princeton solar panel installation expert is a great first step.

EcoWatch's Princeton, NJ Solar Incentives FAQs

If I already have solar panels, can I still claim incentives?

Your best bet is to talk to a representative from the company that installed your solar panels – or get in touch with a local Princeton solar installer — to learn about which incentives you may qualify for. If your solar panels were installed after January 1, 2022, you likely qualify for the recently increased 30% tax credit under the Inflation Reduction Act. Solar panels installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

When does the federal solar tax credit end?

The federal solar tax credit, previously called the ITC and now titled the Clean Energy Credit, is scheduled to end on January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.

Can I qualify for 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 solar panels. Depending on precisely 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 confirm that you are claiming incentives correctly and getting the most money possible.

Can I use both solar and another type 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. Make sure you discuss your ideas with your local Princeton solar installation expert. They can help you plan your project and also help you understand the various incentives that you might or might not qualify for.
