The project submission window for the Illinois Solar for All: Community Solar sub-program opens on Monday, October 6, 2025, at 9 a.m. CT. At that time, Approved Vendors can begin submitting Part I Applications until the window closes on Friday, October 17, 2025, at 5 p.m. CT. Part I Applications must be entered and submitted during this window to participate in the Project Selection Protocol process (if needed).
If sub-program funding remains after the initial project submission window, a rolling submission window will open for Community Solar projects on Monday, January 12, 2026. Projects submitted during the rolling submission window are considered on a first-come, first-served basis until the end of the 2025-2026 program year in May or for as long as remaining sub-program funding is available.
