Summary
Macon County requires a County Board special use permit before any grid-scale commercial solar energy facility is sited, plus a separate commercial solar energy building permit before construction starts. A small rooftop system installed only for a home's or business's own on-site use is not classified as a regulated solar farm under the county's own definition.
COMMERCIAL SOLAR ENERGY BUILDING PERMIT. A permit necessary for the commencement of work performed toward the construction, erection or installation of an approved commercial solar energy facility, substation, supporting facilities, or operations and maintenance building in connection with a commercial solar energy facility. A commercial solar energy building permit may be issued by the county after a commercial solar energy facility has obtained a special use permit from the County Board and the Director of Planning and Zoning determines that all conditions, if any, have been satisfied that are imposed by the special use permit. ... (A) To obtain siting approval, the applicant must first submit a special use permit application to the county. ... (D) The applicant shall submit 12 copies of the special use permit application to the county, and at least one copy in electronic format.
Full Breakdown
Chapter 156 of the Macon County Code governs commercial solar energy facilities, meaning ground-installed systems built primarily to sell power wholesale or retail rather than to serve the property they sit on. 01, a commercial solar energy building permit is the document that authorizes actual construction; the county cannot issue one until the facility has first obtained a special use permit from the County Board and the Director of Planning and Zoning confirms every condition attached to that permit has been satisfied. 04: the applicant must submit a special use permit application containing a detailed project summary, ownership and operator information, a full site plan showing setbacks and adjoining properties, a decommissioning plan, an Agricultural Impact Mitigation Agreement with the Illinois Department of Agriculture, and results from state and federal wildlife review tools, among other items, in 12 paper copies plus one electronic copy.
10 per megawatt of proposed nameplate capacity, with any unused balance refundable within six months of a final County Board decision. 05 caps panel height at 20 feet at full tilt and requires vegetative screening and a six-to-25-foot fence. This entire process applies to grid-scale solar farms, not to typical rooftop panels: the county's own zoning definitions state that solar collectors used for residential or business consumption occurring on-site are not considered a SOLAR FARM, so a homeowner installing rooftop panels for their own use falls outside this special use permit chapter and instead needs only the standard building and electrical permits under Chapter 150.
Violations & Fines
Failing to comply with any Chapter 156 provision, special use permit condition, or other permit requirement is a default under § 156.09. The County Board must give written notice and a 30-day cure period (extendable 60 more days if the applicant is diligently curing), and an uncured default is grounds for revoking the special use permit, in addition to whatever county ordinance remedies otherwise apply.
