How Does the Federal Solar Tax Credit Work?

The federal solar investment tax credit (ITC) is the most financially rewarding incentive for solar buyers. The ITC is the basis of a nationwide government program that allows you to claim a percentage of your solar energy system’s cost on your federal tax bill the year you install it. The percentage has changed since the program’s origin in 2005 but will remain at 30% through 2033. This gives homeowners the chance to save thousands of dollars. 

This tax credit is not a reimbursement but rather a decrease in how much you owe on your tax bill. Additionally, If you don’t owe anywhere near what 30% of your solar expense equals the tax season after your solar installation, you can roll the credit over to the following year. For example, say your total solar expense is $15,000. Applying the federal tax credit would reduce it by $4,500. If you only owe $1,500 on your federal taxes the first year after you install, you can roll over the remaining balance to the next year.

Only those who own their system qualify. Those who financed their system through a solar lease or power purchase agreement (PPA) aren’t eligible. You can claim the solar tax credit when you file your yearly federal tax return, and you should let your accountant know in advance. You must complete IRS Form 5695 if you file your taxes yourself.

Does Maine Offer Net Metering?

Net metering is another way Maine homeowners can save. It doesn’t shave money off up-front but reduces ongoing utility expenses. Most solar buyers have on-grid solar systems, and they send excess power to the grid when their system is producing more than their home is using. Net metering means they get a one-to-one credit for this excess power to offset their electricity consumption at night and on cloudy days. This prevents you from paying out of pocket for times when you rely on the utility grid. 

Learn more about the state’s net metering programs through the Maine Public Utilities Commission.

Can I get free solar panels in Maine?

Yes. You may be eligible for a free solar panel installation in Maine, but you’ll still have to pay for the energy the panels generate.
