The term "solar incentives" refers broadly to financial incentives that are in place to encourage people to use renewable energy by making installing and using solar panels more affordable. You may qualify for various kinds of incentives, such as discounts, cash back or monthly utility bill credits, 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. Categories of solar incentives include:
- Tax Exemptions: Tax exemptions may 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 calculating property tax for your home.
- Rebates: Solar companies may help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also sometimes offer limited-time rebates. If you receive a rebate, that amount will usually be deducted from the total price before tax credits are calculated.
- Net Metering: Net metering becomes relevant after your solar system is up and running. If you've signed a net metering agreement with your Portland utility company, they will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in others you might receive a refund equivalent to a percentage of the value.
- Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.

Federal Solar Incentives
Federal incentives are the kind 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 is a tax credit for a given percentage of your solar system's cost.
The ITC applies to solar panels installed after January 1, 2006 on a primary or secondary residence that you own in the United States. The credit initially covered 30% of the total cost — for panels, labor, accessories and equipment — although it may range from 26-30%, depending on when your solar project was undertaken. There is no cap on the amount you can claim.
Speaking with your local Portland solar panel installation expert is the best way to learn more about how the ITC could apply to you.
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. For solar system installations that begin after January 1, 2022 and are completed by the end of 2032, homeowners can apply for a credit equal to 30% of the total cost. The percentage will then decrease annually until the Clean Energy Credit expires in 2035. Beginning in 2023, it will also be easier to obtain credits for energy storage systems under the new laws.
More information about the new Inflation Reduction Act can be found here. The easiest way to understand how the new Clean Energy Credit will apply to you is to talk with your local Portland solar panel installers.
State & Local Solar Incentives
Some solar incentives are often also provided at the state and local level. Like with federal incentives, these might include rebates, tax credits and more. Some incentives are ongoing, while others are only available for a limited time. Solar incentives may be offered by the Maine government, or by your county or municipality.
Next Steps for Installing Solar in Portland
You can apply for solar incentives from the federal government and the Maine government, as well as from your local utility company. The growing availability of solar initiatives over the last 15 years has helped greatly increase nationwide adoption of solar energy. Contact your local solar panel installer today to find out more information and to save the most money possible on a solar system for your Portland home.
EcoWatch's Portland, ME Solar Incentives FAQs
I already have solar panels. Do I qualify for any incentives?
If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If you had your system installed between 2006 and 2021, you may qualify for a tax credit between 26% and 30%, depending on the date of installation. Speaking with a representative from the company that installed your solar system, or any local Portland solar installer, can help you learn what incentives you can apply for.
How much can I save annually on my electric bill if I add solar panels to my Portland home?
After adding solar panels to your Portland home, you can anticipate savings of approximately $863.31 per year, or approximately $16,402.81 over 20 years.
What are the environmental benefits of switching to solar energy?
Solar energy is a renewable energy source — by switching where you get your energy, you can help lessen the strain on our planet's resources. You can also lower your home's CO2 emissions by 200 pounds annually, or roughly 4,000 pounds over 20 years.
I want to change out my appliances for ones that are more energy-efficient. Are there any benefits I can get?
The recently passed Inflation Reduction Act introduces multiple incentives that reward homeowners who make eco-friendly upgrades. Some incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.
Can I apply for incentives both towards the up-front cost of solar panels, and later as reimbursement?
Yes, you can receive both rebates and tax credits towards the cost of solar panels. Depending on precisely which incentives you are applying for, they may apply in a different order. Make sure that you speak with your solar installer or a local tax professional to ensure that you are claiming incentives correctly and that you're getting the most money possible.
