What an exported kWh is worth in South Carolina
The value of a solar export depends on the credit your utility pays. As an illustration, take 7,000 kWh of solar power in a year, a made-up figure and not a forecast for any home. At the 2025 South Carolina average price of 15.12 cents per kWh, that power is worth $1,058 if the utility credits it at the full retail price. If the utility credits exports at half that rate, it is worth $529.
The gap shows why the export credit matters so much. Ask the utility which applies to you, and use the solar savings calculator to set the retail and export prices separately.

What the federal credits mean in South Carolina
The IRS says the residential clean energy credit, which covered solar panels, does not apply to expenditures made after December 31, 2025, and the home improvement credit does not apply to property placed in service after that date. That is true in every state. What remains are state and utility offers, and the federal home energy rebates that states run. See solar incentives and home energy rebates.
