Solar Funding Programs


GrowSolarChicagolandLogo-08-768x273Grow Solar Chicagoland is a grassroots residential and commercial group purchasing program for solar. Home and business owners throughout the Chicagoland region may participate in this program to help pool their buying power to secure significant discounts that make installing solar more affordable. The program builds on previous years of successful programs that helped over 200 local property owners go solar.

Register now: The Village is partnering with the Library and Grow Solar to offer a Virtual Solar Power Hour on August 25 at 7pm. In this hour-long presentation you’ll learn the basics of solar, how it can save you money, and how the solar group buy program works. Then you are eligible to receive a free, no obligation site assessment from a competitively-selected solar installer to get the ball rolling on a custom quote for your property. 


The Federal Solar Investment Tax Credit: This tax credit deducts a percentage of your solar project costs from your federal income taxes. The credit is 26% and is scheduled to drop to 22% in 2023. 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

The state's solar incentive program will begin accepting new applications for solar projects on September 1, 2022. See this document listing their timeline for application prioritization. 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. This webpage includes updates.

Solar Financing: There are many financial resources available to help you pay for your solar investment. Two common types of loans are: 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).

Illinois Solar for All: Income-qualified customers can get rooftop solar panels at no upfront cost and a guaranteed discount through a state solar incentive program called Illinois Solar for All. Most vendors through Illinois Solar for All require customers to sign up for Power Purchasing Agreements at no upfront cost, but with the guarantee that they will only ever have to pay for half of what their panels produce. So that means that under Illinois Solar for All, if the panels on your roof produced 800 kWh in a month, you would get utility bill credits for those 800 kWh, but would only have to pay your solar company for 400 kWh.

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, which pays off the remaining cost of your system over time. Net metering also helps cover the cost of the electricity your household uses when your panels are not generating energy, like cloudy days or nighttime. Net metering credits are automatically applied to your utility bill—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). If you have ComEd, you will be guaranteed the full net metering rate.

Consumer Protection Resources

Introduction to Rooftop Solar, provided by Citizens Utility Board

Citizens who explore the possibility of utilizing solar power may be interested in learning more about consumer protection as it relates to these types of projects.  The Federal Trade Commission (FTC) has developed a consumer protection webpage that will help people as they research and implement their solar power projects.

Village of Northbrook Solar Renewable Energy Potential Study

In September 2020 paleBLUEdot, LLC presented the Village with a draft Solar Renewable Energy Potential Study to establish community-wide rooftop solar PV potential throughout the Village. Detailed in the report are Solar Financing and Incentives, Village-wide Solar Potentials, Methodologies and Data, Technical and Generational Capacities, Market History and Projections, Summary of Benefits, and Community-wide Solar Recommendations.
