Hannah Solar

Hannah Solar has occupied a distinct position in Georgia's solar landscape since 2009 — that of a full-service engineering, procurement, and construction firm rather than a pure-residential installer. The company's headquarters sit at 1311 Collier Road NW in Atlanta, with a secondary facility on Defoor Hills Road and satellite offices in Asheville, Chattanooga, Greenville, Charleston, Jacksonville, and Bristol. Across that footprint, Hannah Solar describes itself as Georgia's largest turn-key EPC solar firm and reports more than 75 megawatts of completed projects spanning residential rooftops, commercial buildings, industrial sites, and agricultural installations.

What stood out to our research team is the depth of the technical credential set. Hannah Solar is a NABCEP-certified design-build firm, employs NABCEP Certified Solar PV Installers on staff, and is an authorized installer of Tesla Powerwall 2 battery storage. Their published service line covers solar design and construction, EV charging stations, battery storage, backup generators, and ongoing operations and maintenance — meaning the company that designs and installs a Georgia homeowner's system is also positioned to service it long after commissioning. The Better Business Bureau rates Hannah Solar A+, with its BBB file opened in June 2009, and the firm is recognized as a leading solar integrator across the Southeast.

The customer-feedback record is where prospective buyers need to apply scrutiny. Hannah Solar carries a SolarReviews rating of 3.61 out of 5 across eight reviews and a 3.0 overall on Angi, and our research team flagged recurring themes in the negative reviews — unresponsive post-install service, multiple corrective visits to fix portions of a project, and slow coordination on Tesla Powerwall warranty work. The picture is not uniformly negative — many five-star customers praised detailed proposals, realistic production estimates, and clean installations — but the operations-and-service gaps are real and should be addressed in the sales conversation. Prospective customers should ask pointed questions about post-install service-level agreements and Tesla warranty escalation paths before signing.

As an Atlanta-based firm with deep institutional knowledge of Georgia Power interconnection and the EPC-grade engineering required for larger residential systems, Hannah Solar brings capabilities that exceed those of most local installers. With a composite score of 71.2 out of 100, Hannah Solar holds the third-ranked position in Georgia for 2026.
