Full Breakdown
Building-mounted solar under § 4.20.6 A is allowed on any roof face or side/rear facade of principal or accessory structures without a discretionary special permit, but the panel area can't exceed the roof surface it's mounted on. Panels may extend up to 3 feet beyond a pitched roof (4 feet on a flat roof) and no more than 5 feet above a pitched roof's peak, and may project 3.5 feet off a facade or roof edge. No signage is allowed on the array beyond required manufacturer plates. Ground-mounted systems fall under § 4.20.6 B, with separate height and 5-foot setback limits.
Violations & Fines
An oversized or over-projecting array fails zoning or building permit review and must be resized before installation; signage placed on a panel beyond required manufacturer labels violates § 4.20.6 A(6) and is subject to zoning enforcement.
