Guide to Solar Panel Installation in Charleston, South Carolina
Installing solar panels in Charleston is one of the most effective ways to hedge against rising electricity costs. Residential customers in South Carolina pay an average of 15.55¢ per kWh , 11% below the national average. That rate is the single biggest factor in how quickly a system pays for itself.
Local Utility & Climate Considerations:
- Electricity Rate: South Carolina residential average is 15.55¢/kWh (EIA, Electric Power Monthly, Table 5.6.A).
- Federal Incentives (2026): The 30% homeowner credit (Section 25D) ended December 31, 2025. The 48E credit remains through 2027 via lease or PPA.
Installation FAQs:
How much does solar panel installation cost in Charleston?
The average 8kW to 10kW residential system ranges between $18,000 and $25,000. The 30% federal credit homeowners could claim (Section 25D) expired on December 31, 2025, so systems installed in 2026 no longer qualify for it.
What do homeowners in Charleston pay for electricity?
Residential customers in South Carolina pay an average of 15.55¢ per kWh, 11% below the national average of 17.45¢. This rate is the single biggest factor in whether solar pays off: the more you pay the grid, the more each self-generated kilowatt-hour is worth. Source: EIA, Electric Power Monthly, Table 5.6.A.
