The term "solar incentives" covers a range of financial incentives put in place to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Incentives could include things like discounts, cash back or monthly utility bill credits. Some incentives are handled federally, while others are provided by the Illinois government or your specific utility company, county or municipality. Types of solar incentives might include:

  • Rebates: Solar rebates might be offered by your county or state, or by your local utility company. These rebates are essentially cash back that is applied after you purchase solar panels and before tax credits are calculated.
  • Tax Exemptions: These can come in the form of property tax exemptions, which let you exclude the value added by your solar panels when paying property tax on your home. You may also qualify for an exemption on sales tax at the time of purchase.
  • Solar Renewable Energy Certificate (SREC): In general, solar systems that produce more than a predetermined (generally small) amount of electricity qualify for SRECs or other performance-based incentives. SRECs and similar incentives are typically given by your state government. You can sell SRECs to your utility company or another buyer, and the money you receive is normally considered part of your taxable income.
  • Net Metering: Net metering factors in after your solar panels are up and running. If you have a net metering agreement in place with your Maine utility company, the company will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some locations, this is a dollar-for-dollar credit, while in others you may be refunded a percentage of the value.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the federal government.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some familiarity with. The Federal Solar Investment Tax Credit, or ITC, is likely the most well-known federal solar incentive. The ITC allows you to claim a tax credit for a set percentage of the cost of your solar system.

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

Your local Maine solar panel installation expert can offer more information about the ITC and how it applies to your situation.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. At this point, the percentage will be reduced slightly each year until the end of the program in 2035. Starting in 2023, the expansion to the program will also make it easier to get credit for energy storage systems.

State & Local Solar Incentives

Some solar incentives may be provided by state and local governments. Like with federal incentives, these may include rebates, tax credits and more. Certain incentives are offered for only a limited time, while others are ongoing. Local solar incentives may come from your county or municipality, or from the Illinois government.

Next Steps for Installing Solar in Maine

You can qualify for solar incentives from the Illinois government and the federal government, as well as from your local utility company. Growing availability of solar initiatives in the past 15 years has helped greatly increase nationwide adoption of solar energy. Getting in touch with your local Maine solar panel installation company is the right first step towards getting the most money possible when you switch to solar energy.

EcoWatch's Maine, IL Solar Incentives FAQs

If my house already has solar panels, can I still claim incentives?

If your solar panels were installed after January 1, 2022, you may qualify for the newly increased 30% tax credit under the Inflation Reduction Act. If you installed your system between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the date of installation. Reaching out to the company that installed your system, or any local Maine solar installer, can help you learn more about what incentives you qualify for.

How much will a solar system save me on my electric bill in Maine annually?

On average, homeowners in Maine who install solar panels save approximately $707.72 per year, or about $13,446.62 over 20 years after they make the switch.

When does the federal solar tax credit end?

The federal solar tax credit, formerly called the ITC and now titled the Clean Energy Credit, is scheduled 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.

Can I use solar and another type of renewable energy in combination to power my home?

Yes, you can use multiple types of renewable energy to power your home — for example, a combination of solar and geothermal. You can also combine renewable energy generation with a backup source of non-renewable energy. Make sure that you discuss your plan with your local Maine solar panel installer, to make sure you know what you'll need and what incentives you will or won't qualify for.
