State Tax Credit Comparison
South Carolina offers a 25% state income tax credit (capped at $3,500). Georgia offers no state income tax credit.
Net Metering Policies
South Carolina: retail rate net metering active. Georgia: no statewide net metering mandate.
Net metering is often the most economically significant solar policy because it determines how excess production is valued. Retail-rate states (where you receive full retail price for exported energy) have substantially better solar economics than avoided-cost or no-net-metering states.
Average 25-Year Savings
South Carolina: $40,200 over 25 years (avg payback 7.9 yrs). Georgia: $29,800 over 25 years (avg payback 9.5 yrs).
Verdict: Which State Wins on Solar?
South Carolina edges out Georgia on lifetime savings primarily due to more generous state tax credits.
