Solar incentives are intended to make renewable energy usage more affordable via financial incentives to help people install solar panels on their homes. You might qualify for various types of incentives, such as cash back, discounts or credit towards your monthly utility bill, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the state of Maine and others from the federal government. Some solar incentives you might qualify for are:

  • Rebates: A rebate is a partial refund after the purchase of your solar panels. These 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 are dollar-for-dollar reductions (not deductions) in how much income tax you owe the federal government.
  • Net Metering: Don't forget to talk to your South Portland utility company about signing a net metering agreement. This allows you to receive credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Tax exemptions may come in one of two forms. First, there is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption. This allows you to exclude the value added by your solar system when calculating property tax for your house.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives might be the first thing that comes to mind. The solar incentive that you're most likely to have heard of is the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a percentage of the cost of your solar system.

The ITC applies towards solar systems installed after January 1, 2006, and under this program you can deduct from your taxes a percentage of the total cost of solar panels, labor, accessories and equipment. You can receive this credit for solar panels installed on a primary or secondary residence in the United States that you own. Originally, you could claim 30% of the total cost, although the amount you can claim may range between 26-30%. There is no maximum claim amount.

Your local South Portland solar panel installation expert can provide you with more information about the ITC and how it applies to your situation.

The ITC has been renewed and expanded following the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. The Clean Energy Credit lasts until 2035. Your solar installation project undertaken between 2022 and 2032 may qualify for a 30% tax credit. This amount will decrease slightly on a yearly basis until the end of the current program. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

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 can be offered at a more local level. These incentives might be provided by your county or municipality, or by the Maine government. Some are ongoing, while others are available for a limited time.
