Illinois Shines is the brand name of the Adjustable Block Program, a state-administered program for new solar photovoltaic (“PV”) systems. The program provides payment in exchanges for 15 years for renewable energy credits (“RECs”) generated by new PV systems. These payments, made by Illinois utilities, vary depending on the system’s size and where it is located. Participating in Illinois Shines is the same thing as participating in the Adjustable Block Program.
RECs represent the environmental value of the electricity generated from solar panels, but not the electricity itself.
A home PV system might generate 50-200 RECs over 15 years. By participating in Illinois Shines, you will transfer the RECs from your PV system to an Illinois electric utility. Selling your RECs will not affec your PV system’s production.
Although you can keep your RECs or sell them to someone besides utilities, participating in Illinois Shines nd thus allowing your REC to be sold to a utility is lkely to be your best financial option. Selling your RECs through this program will make it more likely that your PV system will save you money.
