Aiken and the Central Savannah River Area (CSRA) are among the strongest solar markets in South Carolina. The CSRA averages 4.8–5.1 peak sun hours per day annually — comparable to Florida’s solar belt — making rooftop solar a financially strong investment for most Aiken homeowners.
Sun hours in the CSRA — Aiken’s 4.8–5.1 peak sun hours/day rank it well above the national average of 4.0. The Sandhills region’s lower cloud cover compared to coastal SC further improves panel production. A 6 kW system in Aiken typically produces 8,500–9,000 kWh annually.
SC solar tax credit — South Carolina offers a 25% state income tax credit on the net cost of a solar installation (after federal credit), capped at $3,500 per year, with a 10-year carryforward. Combined with the 30% federal Investment Tax Credit (ITC), Aiken homeowners can offset 55%+ of installation costs through tax credits.
Net metering — know your provider — Aiken County is served by multiple electric utilities with different net metering policies:
- Dominion Energy SC — Offers retail-rate net metering for systems up to 20 kW. Interconnection application required.
- Aiken Electric Cooperative — Offers net metering to members; check aikenelectric.com for current buy-back rates. Cooperative net metering rates may differ from retail.
Confirm net metering terms with your specific provider before installing. Rates and policies updated periodically.
Roof assessment for Aiken homes — The CSRA’s storm season (June–September) and intense summer UV require solar installers to assess roof condition first. Most panels carry 25-year warranties; a roof under 10 years old is ideal for installation. Aiken’s sandy soil means minimal shading from ground-level vegetation in most neighborhoods.
Getting quotes in Aiken — Use the SC Solar Council directory at scsolar.org to find licensed SC installers. Get at least 3 quotes; prices in the Aiken market typically run $2.50–$3.50/watt installed before incentives.
Payback period — At current Aiken utility rates and with full tax credit capture, payback periods run 7–10 years. With net metering, systems often produce positive cash flow within the first year after installation (once credits are applied).
