Indiana Solar Incentives, Tax Credits, & Rebates (2025 Guide)

This guide will walk you through all the major solar incentives and policies available to Indiana residents in 2025. We’ll clarify how each program works, who’s eligible, and how they contribute to your solar investment.

Federal Solar Incentives: The Investment Tax Credit (ITC)

The most significant financial incentive for homeowners nationwide is the federal Solar Investment Tax Credit (ITC). This is a dollar-for-dollar credit that directly reduces the amount of federal income tax you owe.

• Credit Amount: For systems installed between 2022 and 2032, the ITC allows you to claim 30% of the total cost of your solar energy system.
• Impact: On a $20,000 solar system, the 30% ITC provides a $6,000 credit, effectively lowering your net cost to just $14,000.

Indiana’s State & Local Solar Incentives

Indiana’s primary state-level benefit is its property tax exemption, complemented by the state’s Excess Distributed Generation policy (Indiana’s version of net metering).

Indiana Property Tax Exemption for Solar

• How it Works: Indiana law provides a 100% property tax exemption for the value added to a home by a solar energy system. While solar panels increase your home’s value, this exemption ensures your annual property tax bill will not go up.
• Impact: This is a significant long-term benefit that saves you hundreds of dollars every year for the life of your system.

Utility-Specific Solar Programs in Indiana

Excess Distributed Generation (EDG) Policy

• How it Works: Indiana’s EDG policy is the successor to traditional net metering. When your panels generate more power than you are using, the excess is sent to the grid, and you receive a credit on your bill from your utility (like Duke Energy Indiana, NIPSCO, or AES Indiana). The credit you receive for exported power is calculated at 125% of the wholesale rate, which is lower than the full retail rate.
• Impact: While not as lucrative as 1-to-1 net metering, this program still significantly reduces your electricity bills and is the foundation of the financial return for solar in Indiana.

Understanding the Full Cost of Solar

To appreciate how these powerful incentives work, it’s important to understand the total cost of a solar project they are designed to reduce. A complete solar installation includes panels, inverters, racking, and professional labor, all of which are eligible for the 30% federal tax credit. For a detailed breakdown of what goes into the price of a system, see our complete guide on The Cost of Solar Panels in Indiana.

The available financial incentives are a key reason why solar is a worthwhile investment in Indiana.

This makes solar accessible even without a large initial capital outlay. Our complete guide, How To Get Free Solar Panels in Indiana, breaks down how these options work.
