Summary
Rooftop and freestanding solar panels are an accessory use allowed in every unincorporated Guilford County zoning district under UDO Sec. 5.14.E, no special permit required. Roof-mounted panels on a single-family home must lie flush and integrated with the roof surface, while freestanding backyard arrays are capped at twelve feet tall, side or rear yard only, and twenty-five percent of the house's heated square footage. Ground-mounted commercial solar farms need a Special Use Permit.

Full Breakdown
Guilford County treats home solar panels as an accessory use under UDO Sec. E, meaning a homeowner does not need a Special Use Permit or rezoning to add them, only compliance with the ordinance's dimensional standards before pulling a building permit. Roof-mounted systems are allowed in every zoning district. On a single-family home or its accessory buildings, the panels, tiles or shingles must be integrated as the surface layer or mounted flush against the roof rather than tilted up on racks; that flush-mount rule does not apply to non-single-family buildings, which can match the district's regular maximum building height instead.
A freestanding, ground-mounted system is allowed only as an accessory to a single-family home in a residential district, and it comes with three hard limits: the panel array cannot exceed twenty-five percent of the primary residence's heated square footage, the structure cannot rise above twelve feet measured from grade to its apex, and it must sit in a side or rear yard, never the front. A larger, ground-mounted solar farm is a different use category, Solar Collectors Principal, under UDO Sec. D, confined to the AG, PI, LI and HI districts, and it requires a Special Use Permit under Sec.
Q plus 100 feet of separation from any residential structure, a 25-foot height cap, vegetative screening, and a recorded decommissioning plan filed with the Guilford County Register of Deeds. Both project types are reviewed by the Guilford County Planning and Development Department, and because Greensboro and High Point administer their own zoning codes, these standards apply only in the unincorporated county.
Violations & Fines
Installing a freestanding solar array over twelve feet tall, larger than twenty-five percent of the home's heated area, or set in a front yard violates UDO Sec. 5.14.E. Building a ground-mounted solar farm without a Special Use Permit under Sec. 3.5.Q, or without a filed decommissioning plan, violates Sec. 5.14.D. Sec. 1-14 sets a default penalty of up to $500 and 30 days in jail per offense with no listed fine, each day of noncompliance a separate offense, and a warning citation before any civil penalty.
