Community solar allows businesses and consumers in Illinois to save 5-10% on their electric bills. Illinois passed legislation in 2017 to encourage the development of community solar and other small renewable energy facilities, providing for Shared Net Energy Billing. This allows you to benefit from the renewable energy produced on a community solar farm. You will keep your current electric utility and start seeing a credit on your monthly bill from your community solar project. Here are some additional resources.
