Process Framework for Georgia Solar Energy Systems
Installing a solar energy system in Georgia involves a structured sequence of technical, regulatory, and utility-coordination steps that differ in important ways from the generic national model. This page maps the full process framework — from initial site evaluation through utility interconnection — with attention to the Georgia-specific agencies, codes, and handoff points that govern each stage. Understanding the process structure helps property owners, contractors, and project managers anticipate where delays occur and what documentation is required at each transition.
The Standard Process
The standard process for deploying a residential or commercial solar energy system in Georgia follows six discrete stages: site assessment, system design and engineering, permitting, installation, inspection, and utility interconnection. Each stage produces deliverables that gate entry into the next. No stage is optional; skipping or abbreviating any stage creates compliance gaps that can block interconnection approval or void equipment warranties.
Georgia's framework is shaped by multiple overlapping authorities. The Georgia Department of Community Affairs (DCA) administers the State Minimum Standard Codes, which include the National Electrical Code (NEC) — currently adopted as NFPA 70 (2023 edition) — and the International Residential Code (IRC) or International Building Code (IBC) depending on occupancy type. Local jurisdictions (counties and municipalities) administer building and electrical permits under authority delegated by the DCA. Georgia Power, the state's largest investor-owned utility, and the state's Electric Membership Corporations each maintain separate interconnection tariffs and application portals.

Scope and Coverage
This resource covers solar within Georgia. It is intended as a reference guide and does not constitute professional advice. Readers should consult qualified local professionals for specific project requirements. Content outside Georgia is addressed by other resources in the Authority Network.
Phases and Sequence
The six phases unfold in the following order:
- Site Assessment and Feasibility
The installer evaluates roof condition, structural load capacity, shading analysis (typically using tools such as Solargraf or Aurora Solar), available roof area in square feet, and the electrical panel's amperage rating. Georgia averages approximately 218 sunny days per year, but site-specific shading from trees or adjacent structures can reduce energy yield by 10–25%. A written site assessment report is the expected deliverable. - System Design and Engineering
A licensed electrical engineer or qualified designer produces stamped plans showing panel layout, string configuration, inverter specifications, conduit routing, and grounding scheme. Plans must reference NEC Article 690 (Solar Photovoltaic Systems) compliance under the 2023 edition of NFPA 70 and, for roof-mounted arrays, comply with applicable wind-load requirements under ASCE 7. Georgia's coastal and southern counties face higher wind exposure categories than the piedmont and mountain regions. - Permitting
The contractor submits stamped plans to the local jurisdiction's building and electrical departments. Permit fees and timelines vary: Fulton County and the City of Atlanta operate separate permitting tracks, while rural counties may process permits through a single combined office. A building permit, an electrical permit, and in some cases a zoning or land-use approval are each distinct filings. - Installation
Licensed electrical contractors complete the physical installation. Georgia O.C.G.A. § 43-14 governs electrical contractor licensing through the Georgia Secretary of State's Licensing Division. Installers must hold an active state electrical license; NABCEP (North American Board of Certified Energy Practitioners) certification is a recognized professional credential but does not substitute for the state license. - Inspection
The local authority having jurisdiction (AHJ) conducts a rough-in electrical inspection before any system components are energized and a final inspection after completion. Inspectors verify NEC 690 compliance under the 2023 edition of NFPA 70, proper labeling (required at all disconnects, combiner boxes, and the utility meter), and structural attachment. - Utility Interconnection
Following a passed final inspection, the installer submits an interconnection application to the serving utility. For Georgia Power customers, this follows the company's Distributed Generation Interconnection tariff (Schedule DG). Processing timelines for systems under 10 kW (AC) typically run 10–30 business days after a complete application is submitted.
Entry Requirements
Entry requirements differ by phase but share a common thread: each phase requires documented completion of the prior phase before proceeding.
Phase 1 → Phase 2: A completed site assessment, a signed customer agreement, and confirmation of structural adequacy (roof age, truss spacing, and load-bearing capacity).
Phase 2 → Phase 3: Engineer-stamped drawings that reference the 2023 edition of NFPA 70 and the applicable edition of the IBC/IRC adopted by Georgia DCA, along with a single-line electrical diagram.
Phase 3 → Phase 4: Issued building and electrical permits, physically posted at the job site.
Phase 4 → Phase 5: Rough-in inspection approval documented on the permit card before final wiring and energization.
Phase 5 → Phase 6: Signed final inspection approval from the AHJ and a copy of the certificate of occupancy or equivalent closeout document.
The regulatory context for Georgia solar energy systems provides detailed citation of the statutory and tariff instruments that define these requirements at each stage.
A contrast worth noting: grid-tied systems (the dominant installation type in Georgia) require both AHJ approval and utility interconnection approval before operation. Off-grid systems require only AHJ permitting because they do not connect to the utility grid, eliminating the interconnection phase entirely.

Handoff Points
Three handoff points carry the highest risk of delay or rework in Georgia solar projects:
Permit Submission Handoff: Incomplete or unstamped plans are the leading cause of permit rejection. The handoff between the system designer and the permitting contractor must include a complete document package: stamped engineering drawings referencing the 2023 edition of NFPA 70, a single-line diagram, a roof plan with dimensions, a site plan showing setbacks, and equipment cut sheets for all major components.
Inspection Handoff: The AHJ inspector must receive advance notice (typically 24–48 hours) per local jurisdiction rules. Failure to schedule rough-in inspection before energizing the DC array is a code violation under NEC 690.13 (disconnecting means requirements) as specified in the 2023 edition of NFPA 70.
Utility Interconnection Handoff: Georgia Power and EMC interconnection applications require the installer to submit the final inspection documentation, an as-built single-line diagram, and signed interconnection agreements. Missing any one document resets the utility review clock. The Georgia Solar Authority home resource maintains reference links to the current interconnection application portals for major Georgia utilities.
Systems qualifying for net metering under Georgia's applicable tariffs receive a bi-directional meter installed by the utility after interconnection approval — a utility-side action that the property owner or installer cannot perform independently.
