Since its inception in 1975, it has helped countless Illinoisans go solar, providing a directory of proven professionals in the solar energy and storage industries. More importantly, it’s helped create a stable set of regulations and incentives at the state level and kept the business community informed of the changes in policy that might affect them. ISEA does public education webinars and consumer protection, as well.
