Ridgefield, CT Solar Energy: Panel Permits (2026)

16 of the Ridgefield Zoning Regulations, Renewable Energy Systems, splits solar rules into roof-mounted and ground- or pole-mounted arrays. A roof-mounted system must sit within the yard setbacks that already apply to structures in its zoning district and can't extend past the roof's eaves or edges; it also can't push the building above the district's overall height limit, though panels on a pre-existing, legally nonconforming structure are excused from the setback rule. Ground-mounted or pole-mounted systems, treated as accessory structures, must sit entirely outside the required side or rear yard setbacks.

On lots smaller than 20,000 square feet, coverage is capped at 10% of total lot area and height at four feet from grade; on larger lots the cap rises to 12 feet for a fixed array or 18 feet if the system uses a solar tracker, unless the Planning and Zoning Commission approves something taller based on the site's location and screening. Every ground-mounted application needs a landscaping plan showing screening from neighbors, compliance with local, state and federal electrical and construction codes, and buried wiring run in conduit rather than overhead.

15 and the Ridgefield Noise Ordinance. Applicants may need to submit a certified survey, manufacturer specifications and a sun-and-shadow study before the Zoning Enforcement Officer or Commission signs off.
