Solar incentives encourage homeowners to switch their home over to renewable energy by providing incentives meant to lower the financial burden of solar panel installation and use. Incentives may include things like discounts, cash back or monthly utility bill credits. Some incentives are offered federally, while others are offered by the state of New Hampshire or by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: Tax exemptions can come in one of two forms. First, there is sales tax exemption, which is applied at the time you purchase your solar panels. The second is property tax exemption. This allows you to ignore the added value of your solar system when paying property tax on your house.
  • Net Metering: Be sure to speak to your Windham utility company about signing a net metering agreement. This allows you to get a credit towards your monthly utility bill for the value of excess energy your solar panels generate. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar system. States or counties will also offer limited-time rebates at various times. Any rebates you receive will usually be deducted from the total price before any tax credits are calculated.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, how much income tax you owe the federal government. Tax credits differ from tax deductions.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives are likely the first thing that comes to mind. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit that reduces your taxes by a predetermined percentage of the money you spend installing solar panels.

The ITC applies to the total cost of installing a solar system, including the panels themselves as well as labor, equipment and accessories. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence that you own and that is located in the United States. 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 amount you can claim.

To find out exactly how much the ITC could save you, contact your local Windham solar panel installer.

The Inflation Reduction Act, passed in August 2022, expanded and extended the ITC (as well as retitling it the Clean Energy Credit). The Clean Energy Credit runs until 2035. Solar installation projects started after January 1, 2022, and completed by the end of 2032 may qualify for a 30% tax credit; this amount will be decreased slightly each year until the current program ends. Starting in 2023, it will also be easier to obtain credits for energy storage systems under the new laws.

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. Some incentives are ongoing, while others are available for a limited time. These incentives may be provided by your county or municipality, or by the New Hampshire government.

Next Steps for Installing Solar in Windham

The large number of available solar incentives has enormously increased the adoption of solar energy nationwide over the last 15 years. You can get solar incentives from the federal government, the New Hampshire government or from your local utility company. Contact your local solar panel installer today to discover more about the various programs and to save the most money possible on a solar system for your Windham home.

EcoWatch's Windham, NH Solar Incentives FAQs

I already have solar panels installed. Do I qualify for any incentives?

An excellent idea would be to talk to the company that installed your system – or call a local Windham solar installer — to better understand which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly 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 Clean Energy Credit (formerly named the federal solar tax credit, or ITC), is scheduled to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

I want to trade in my old appliances for ones that are more energy-efficient. Are there any incentives I can get?

Under the new Inflation Reduction Act, there are a number of 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.

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

Many solar incentives apply to a property you own that is located within the United States; most secondary residences will fall under this distinction. There may be other solar incentives available for commercial properties, depending on the specifics. We recommend reaching out to your local solar installer and/or tax professional to better understand what incentives apply to your specific situation.
