Solar Funding Programs


The Federal Solar Investment Tax Credit: This tax credit deducts a percentage of your solar project costs from your federal income taxes. With the passage of the Inflation Reduction Act, the credit is now 30% from 2023 to 2032. You must own your panels to receive the tax credit. The system must be installed before the end of the year, and you must pay federal taxes to benefit. If the credit amounts to more than you paid in federal taxes in a single year, it can roll over for up to five years. Learn more about the residential energy credit (Form 5695) on the IRS website or on the Solar Energy Industries Association website


An overview for navigating state incentives: DSIRE Renewable Energy Incentives in Illinois

Illinois Shines: The state will provide a monetary incentive for renewable energy credits generated over a solar installation’s first 15 or 20 years of operation for accepted projects. Many different project types are eligible, however interested parties can only apply for funding through approved vendors. With questions, reach out to the program administrator at or 877-783-1820. For more information, click here. This webpage also includes updates.

Illinois Solar for All: Income-qualified customers can get rooftop solar panels at no upfront cost and a guaranteed discount on the electricity generated from the system. For example, if an individual uses $100 worth of electricity from the system, the Vendor cannot charge them more than $50. For more information, click here.  

On-bill Credits from your Electric Utility: In ComEd territory, excess electricity is sent back to the grid and you’ll receive bill credits for that electricity in a process called “net metering.” These credits help maximize your monthly bill savings and ensure you’re credited for every kWh your system produces. Net metering credits are automatically applied to your utility bill, so you will not receive direct payments from your utility company. ComEd is required by state law to offer net metering: unused net metering credits rollover each month, but they “expire” every year (either April 30th or October 30th).

Solar Financing: There are many financial resources available to help you pay for your solar investment. Two common types of loans: bridge loans (covers the period between installing a system and receiving your incentives) and solar loans (offered by banks, credit unions and solar panel manufacturers).
