Your application paperwork

Illinois Shines is the state's solar incentive program. It pays for the Renewable Energy Credits your rooftop or community solar produces, and an Approved Vendor passes that value to you as an upfront discount or payments, lowering the cost of going solar. You do not apply to Illinois Shines directly; you choose an Approved Vendor (your solar installer), who submits and manages the application for you. Income-qualified households can receive higher incentives.

Steps to apply

  1. Visit the Illinois Shines site to understand the program and the project types (rooftop or community solar).
  2. Use the vendor finder to choose an Approved Vendor or Designee (your installer).
  3. Have the vendor design your solar project and submit the Illinois Shines application on your behalf.
  4. Review and sign the vendor's disclosure forms and contract before work begins; the incentive is reflected in your pricing.

Documents you will likely need

  • Proof you own the home and a recent electric bill (the installer uses these to size the system).
  • The vendor's standard disclosure forms and contract, for you to review and sign.
  • For income-qualified incentives, proof your household income is within the limit.
  • Your utility account information.
