The term "solar incentives" includes a range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. You may be eligible for various kinds of incentives, including 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 Maine government and others from the federal government. Types of solar incentives might include:

  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar system. States or counties will also sometimes offer limited-time rebates. Any rebates you receive will usually be deducted from the total price before tax credits are calculated.
  • Tax Exemptions: These could come in the form of property tax exemptions, which let you ignore the value added by your solar panels when paying taxes on your house. You could also look for exemptions on sales tax at the time of purchase.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the federal government.
  • Net Metering: You may be able to sign a net metering agreement with your Lewiston utility company. This agreement may apply to all or a percentage of the excess electricity your solar panels generate. They will then deduct this value from your utility bill each month.

Federal Solar Incentives

Federal solar incentives are probably the first thing that comes to mind when thinking about solar incentives. The Federal Solar Investment Tax Credit, or ITC, is 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 was originally for 30% of the total cost of solar panel installation, and has fluctuated slightly over the years between 26-30%. The percentage you qualify for will depend on when your solar system was installed. The cost of installation includes the panels themselves as well as the cost of labor, accessories and equipment. There is no maximum amount you can claim. The ITC applies to solar systems installed after January 1, 2006, on your primary or secondary residence. The residence must be owned by you and in the United States.

To more fully understand how the ITC will apply to your situation, call your local Lewiston solar panel installer and request more information.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. The new Clean Energy Credit extends until 2035. Homeowners can now receive a 30% credit for solar systems that began installation on or after January 1, 2022, and will be done by December 31, 2032. This credit will then decrease annually until the date of expiration. The expansion also makes credits for energy storage systems even easier to claim, starting in 2023.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these could include rebates, tax credits and more. Some incentives are offered for only a limited time, while others are ongoing. These local incentives could come from your county or municipality, or from the Maine government.

Next Steps for Installing Solar in Lewiston

Can I apply 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 confirm that you are claiming the correct incentives and getting the most money you can.

Can I receive any incentives when I add solar panels to a rental property, vacation home or commercial property?

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