Eagan, MN Solar Energy: Panel Permits (2026)

Item 3 ties roof-mounted panel setbacks to the mechanical-equipment setback rule and adds a hard floor: at least one foot back from the roof edge on residential structures, or the distance the Minnesota State Building Code sets for commercial, industrial and institutional buildings. Ground-mounted systems instead follow the accessory-structure setback for whatever zoning district they sit in, while a community solar garden or solar farm has to meet the larger principal-structure setback for that district. Item 4 governs height: a roof-mounted panel on a house can tilt for efficiency, but its highest point cannot sit more than three feet above the roof surface it is mounted on.

Ground-mounted systems max out at 12 feet, though the code lets that rise by up to an additional 15 feet, for a possible 27-foot total, if the owner pulls the system back an extra two feet from the property line for every additional foot of height above 12 feet. Item 7 caps surface coverage too: a roof-mounted system cannot cover more than 80 percent of the south-facing roof area or of an entire flat roof, and ground-mounted arrays count toward an overall lot-coverage cap of 30 percent in residential districts and 70 percent in commercial, industrial and institutional districts.

Items 5 and 6 add aesthetic conditions: panel color does not have to match the roofing, but reflective glare must be pointed away from neighboring windows, and non-residential roof-mounted systems need screening under the chapter's general screening standards unless screening would cut into the panels' output.
