The Federal Solar Tax Credit, Explained in Plain English

The federal tax credit is one of the biggest reasons solar has become affordable. Here's how it actually works.

What the credit does

It lets you claim a percentage of your total solar system cost as a credit against what you owe in federal income taxes — not a rebate check, but a reduction in your tax bill.

Who's eligible

Generally, homeowners who purchase (rather than lease) their solar system and owe federal taxes can claim the credit — consult a tax professional for your specific situation.

What it covers

Typically the credit applies to the full cost of the solar system and installation, and can extend to battery storage in many cases.

Rates can change over time

Federal incentive percentages have changed over the years and may again — always verify the current rate before finalizing your financial planning.

It stacks with state incentives

Many states and utilities offer their own rebates or incentives on top of the federal credit — worth researching what's available in your specific area.
