Do I need a permit for solar panel installation in Richland County (Unincorporated)?
Yes. In South Carolina, solar panel installation generally requires a permit, and Richland County (Unincorporated) is no exception.
Utility interconnection and net metering approval is a separate process from the building permit and is handled by your electric provider. In coastal Charleston, roof-mounted arrays must account for wind uplift and roof structural capacity, so a structural review is common. County Code Sec. 6-43 requires a separate permit for each installation of electrical equipment. Solar energy conversion systems are permitted by right as an accessory use in every zoning district, but under LDC Sec. 26-4.3(d) a roof-mounted system may extend no more than 3 feet above the roofline, and systems must not produce unreasonable glare on neighboring properties. Ground-mounted systems follow the accessory structure location rules in LDC Sec. 26-4.3(b): not in front of the house's building line and at least 5 feet from property lines in a rear yard.
