Do I need a permit for solar panel installation in Carrollton?

Most likely yes. Solar panel installation usually requires a permit in Georgia. Confirm the specifics with Carrollton.

Georgia has no statewide solar permit exemption; expect both a building permit and an electrical permit from the local authority having jurisdiction. Some jurisdictions offer an expedited residential solar process; requirements and utility interconnection sign-off still vary by locality and power provider. Carroll County's own permitting office is the Carroll County Community Development Department, reachable on 770-830-5861 at https://www.carrollcountyga.gov/158/Community-Development-Department. Its online permit portal is https://carrollcountyga.eps.cloud/eps/index.html. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. Solar involves a building permit for the attachment and a separate electrical permit, plus a utility interconnection that runs outside the permit process. Carrollton issues electrical permits through its combined residential electrical, HVAC, plumbing, and gas application, which requires copies of the contractor's state license and business license. Processing can take 2 to 3 business days. Inside a designated Carrollton historic district or on a designated historic property, no material change in appearance can be made until the Historic Preservation Commission approves a certificate of appropriateness (UDO 3.05.11). Carrollton issues building, electrical, HVAC, plumbing, gas, and pool permits at City Hall, 315 Bradley Street (770-830-2000), and every permit must be picked up in person by the Georgia state card holder. Someone else picking it up needs a notarized affidavit.
