Solar incentives mitigate the cost of installing solar panels on your home. These financial incentives are intended to encourage more people to convert their home partially or fully to renewable energy. Various kinds of incentives, including cash back, discounts or credit towards your monthly utility bill, might be available to you. Some incentives may be provided via the Maine government, by your utility company or by county or municipality, while others are federal. Some broad categories of solar incentives include:

  • Net Metering: Make sure you talk to your Orono utility company about signing a net metering contract. This will allow you to receive credit towards your monthly utility bill for the value of excess energy your solar panels generate. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Credits: Tax credits lower, dollar-for-dollar, how much income tax you owe the federal government. Tax credits are different from tax deductions.
  • Rebates: Rebates, or partial refunds after a purchase, are typically given prior to any solar tax credits being calculated. Rebates may be given by your local utility company, by your state or by your county.
  • Tax Exemptions: Tax exemptions can come in one of two forms. First, there is sales tax exemption, which is applied when you purchase solar panels. The second is property tax exemption. This allows you to ignore the value added by your solar system when paying property tax on your house.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives may be the first thing that comes to mind. One of the incentives many people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specified percentage of your solar system's cost.

The ITC initially applied to 30% of the total cost of solar system installation, 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 cost of installation includes the panels themselves as well as the cost of equipment, accessories and labor. There is no maximum claim amount. The ITC applies 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 best understand how the ITC might apply to you, call your local Orono solar panel installer and ask for more information.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as renaming it to the Clean Energy Credit). The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar systems installed between 2022 and 2032. After this, the percentage will see a slight decrease annually until the program expires in 2035. Starting in 2023, it will also be easier to claim credits for energy storage systems under this new program.

More information about the new Inflation Reduction Act can be found here. To fully understand how the new Clean Energy Credit applies to you, get in touch with your local Orono solar installation company.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Tax credits, rebates and more can be offered at a more local level. These incentives — which may be provided by your county or municipality, or by the state of Maine — might be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Orono

Nationwide solar energy use has gone up significantly in the last 15 years, in part thanks to the growth in the number of solar incentives. You might receive these incentives from the Maine government, the federal government or your local utility company. Speaking with your local Orono solar panel installation expert is an excellent first step towards getting all the incentives you qualify for when you switch to solar energy.

EcoWatch's Orono, ME Solar Incentives FAQs

How do I know if I qualify for solar incentives?

Broadly, solar incentives apply to:

  1. a new solar panel system
  2. installed on a property that you own
  3. within the U.S.
  4. within the date range specified by a particular incentive.

Specific incentives, including ones handled by the Maine government or by your county/municipality, sometimes have additional qualifications. Talk to your local Orono solar installer to find out what incentives your project may qualify for.

If I already have solar panels, can I still claim incentives?

If your solar panels were installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If your system was installed between 2006 and 2021, you may qualify for a tax credit between 26% and 30%, depending on the exact installation date. Talking to the company that installed your system, or any local Orono solar installer, can help you learn what incentives you qualify for.

How much will solar panels save me annually on my electric bill in Orono?

When you add solar panels to your house in Orono, you can expect to save about $857.98 per year, or approximately $16,301.68 over the next 20 years.

When does the federal solar tax credit end?

The federal solar tax credit, formerly known as the ITC and now titled the Clean Energy Credit, is set to end January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.
