Legal Status: Can You Plug In Solar in Illinois?

Current Disposition: Balcony solar bill failed

Illinois has no law addressing balcony solar. SB 3104 (PLUG-IN SOLAR ENERGY SYSTEMS), as amended in committee, would exempt qualifying plug-in solar devices from interconnection requirements, replace pre-approval with notice to the electricity provider within 30 days of installation, and protect tenants and homeowners' association members who install systems that export no more than 1,200 watts. The Senate Energy and Public Utilities Committee passed it on March 12, 2026. It was re-referred to Assignments on May 22, 2026 and has not moved since. The similar House bills HB 4524 and HB 4371 were re-referred to the Rules Committee on March 27, 2026.
