The term "solar incentives" generally refers to financial incentives implemented by the government and by solar companies to encourage the use of renewable energy by making the installation and use of solar panels more affordable. You might qualify for various types of incentives, such as discounts, cash back or credit towards your monthly utility bill, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the state of New Jersey and others from the federal government. You might qualify for any of the following types of solar incentives:

  • Net Metering: You may be able to sign a net metering contract with your Williamstown utility company. This agreement may apply to all or a percentage of the excess electricity that is generated by your solar panels. They will then subtract this value from your utility bill each month.
  • Tax Exemptions: These can come in the form of property tax exemptions, which allow you to exclude the value added by your solar panels when paying taxes on your home. You could also look for exemptions on sales tax at the time of purchase.
  • Rebates: A solar rebate is a partial refund after the purchase of your solar system. Rebates may be offered by your local utility company, your county or your state. The cash back that you get from the rebates is normally applied before tax credits are calculated.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, how much income tax you owe the government. Tax credits differ from tax deductions.
  • 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. Typically, you must meet a certain (small) threshold of energy production before your solar system qualifies for SRECs or similar performance-based incentives. These kinds of incentives are normally handled at the state level.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have heard of. A federal incentive that most people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specific percentage of the cost of your solar system.

The ITC was originally for 30% of the cost of installing a solar system, and has fluctuated slightly over the last few years between 26-30%. The installation date of your solar system will determine what percentage you qualify for. The total installation cost includes the panels themselves as well as the cost of equipment, accessories and labor. There is no maximum claim amount. The ITC can be applied to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be in the United States and owned by you.

To better understand exactly how much money the ITC could save you, get in touch with your local Williamstown solar panel installation expert.

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Homeowners can now qualify for a credit of 30% of the total costs of solar system installation for projects that began after January 1, 2022, and will be finished by the end of 2032. The credit percentage will then decrease on a yearly basis until the Clean Energy Credit expires in 2035. Starting in 2023, the expansion will also make it easier to get credit for energy storage systems.

More information about the new Inflation Reduction Act can be found here. The easiest way to understand how the new Clean Energy Credit will apply to you is to reach out to your local Williamstown solar panel installation expert with your questions.

State & Local Solar Incentives

There are more than just federal solar incentives; rebates, tax credits and more are often offered at the state and local level. Incentives might be provided by the state of New Jersey, or by your county or municipality. Certain incentives might only be available for a limited time, while others are ongoing.

EcoWatch's Williamstown, NJ Solar Incentives FAQs

How can I learn if I qualify for different solar incentives?

It's a smart idea to get in touch with your local Williamstown solar installer for a better understanding of which incentives your project may qualify for. Generally, solar incentives apply to new solar systems installed on a property you own (in the U.S.) within a specified date range. Some incentives, such as those given by the state of New Jersey, may have additional requirements.

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 solar system – or speak to a local Williamstown 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 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%.

I want to switch my appliances out for ones that are more energy-efficient. Are there any incentives I can claim?

With the passage of the new Inflation Reduction Act, there are a number of new financial incentives for making eco-friendly improvements to your home. More details about these incentives, including information about incentives for purchasing new appliances, can be found here.

What if I want to add a solar system to a vacation home, rental property or commercial property? Will I still qualify for incentives?

While we recommend speaking with your local solar installer and/or tax professional to best understand what solar incentives apply to you, many incentives can be claimed on a second home, provided that it is in the United States and owned by you. There may be additional incentives available specifically for commercial properties, depending on the details.
