Save the Date! On September 21st, 2025 – the Fall Equinox – we will come together to celebrate power from the sun and show the widespread public support and demand for the energy revolution.

Sun Day in the greater Greater Chicago region celebrates the rise of clean energy and the movement to leave fossil fuels behind. Timed with the fall equinox—a moment of transition—we’ll come together to showcase the power of clean, renewable energy sources that can power the state and our world.

ISEA Solar Ambassadors will be at this event to tell their solar stories!
