Solar incentives are designed to make renewable energy usage more affordable via financial incentives to help people install solar panels on their homes. You might qualify for several kinds of incentives, such as cash back, discounts 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 Maine government and others from the federal government. Some broad categories of solar incentives include:

  • Rebates: A rebate is a partial refund after the purchase of your solar system. Rebates might be offered by your local utility company, your county or your state. The rebates are usually applied before calculating tax credits.
  • Tax Exemptions: Tax exemptions may come in 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 exclude the added value of your solar system when calculating property tax for your house.
  • Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.
  • Net Metering: Be sure to talk to your Lewiston utility company about signing a net metering contract. This will allow you to get a credit towards your utility bill every month 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.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some familiarity with. One of the incentives many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specific percentage of your solar system's cost.

The ITC can be applied to solar panels installed after January 1, 2006, on a primary or secondary residence in the United States that you own. Initially, the credit applied to 30% of the total cost – for panels, accessories, equipment and labor – although it may range from 26-30%, depending on when your solar system was installed. There is no cap on the claim amount.

Talking to your local Lewiston solar panel installer is the best way to understand how the ITC may apply to you.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as retitling it the Clean Energy Credit). The Clean Energy Credit is valid until 2035. Your solar installation project undertaken between 2022 and 2032 may qualify for a 30% tax credit; the amount will decrease slightly each year until the current program ends. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. The best way to understand how the new Clean Energy Credit might apply to you is to get in touch with your local Lewiston solar panel company.

State & Local Solar Incentives

Some solar incentives are often also provided by state and local governments. Like with federal incentives, these could include rebates, tax credits and more. The incentives — which may be provided by your county or municipality, or by the state of Maine — may be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Lewiston

Nationwide solar energy use has significantly increased in the past 15 years, in part thanks to the increase in availability of solar incentives. You might receive these incentives from your local utility company, the Maine government or the federal government. We recommend talking to your local Lewiston solar installation expert to learn more about these incentives and to be sure that you're getting the largest number possible for your solar panels.

Can I qualify for incentives both towards the up-front cost of solar panels, and later as reimbursement?

Yes, you can receive both tax credits and rebates towards the cost of your solar panels. Depending on which incentives you are applying for, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to verify that you are claiming the correct incentives and that you're getting the most money you can.

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

While we recommend getting in touch 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, as long as it is in the United States and owned by you. There may be other incentives available specifically for commercial properties, depending on the details.
