The renewable energy sector continues to expand, despite policy uncertainty under the Trump administration.
South Carolina Solar Incentives: 2025 Overview
South Carolina offers valuable incentives to make solar energy affordable. Homeowners can benefit from the 30% Residential Clean Energy Credit and an additional state tax credit, significantly reducing installation costs. The state’s net metering program allows residents to earn credits for excess energy, lowering future bills. Going solar in South Carolina is a smart choice…

Residential Clean Energy Credit
The Clean Electricity Investment Credit (previously called the Federal Investment Tax Credit) helps lower the cost of installing solar panels by 30%. This credit covers everything: the solar panels, equipment, labor, permits, and even sales tax.
For example, as of 2025 the average cost of a 10 kW solar system in the U.S. typically ranges between $21,000 and $29,500 before applying any federal tax incentives. After claiming the 30% Clean Electricity Investment Credit, the price drops to around $14,980 to $21,070, depending on the state and other factors like equipment quality and labor costs.
To claim this credit, you must buy your solar system with cash or a loan (leases don’t qualify). You also need to owe enough in taxes to claim the credit, but if you don’t, you can carry it over to future years until 2034.

Claiming the Clean Electricity Investment Credit is simple!

Summary
SC Solar Energy System Credit
Code Section 12-6-3587 provides a corporate or individual tax credit of 25% of the costs incurred by a taxpayer in the purchase and installation of a solar energy system or small hydropower system for heating water, space heating, air cooling, energy-efficient daylighting, heat reclamation, energy-efficient demand response, or the generation of electricity in or on a facility in South Carolina and owned by the taxpayer. The taxpayer may not claim the credit before installation is complete. The amount of the credit in any year may not exceed $3,500 for each facility or 50% of the taxpayer’s tax liability for that tax year, whichever is less. If the amount of the credit exceeds $3,500 for each facility, the taxpayer may carry forward the excess for up to 10 years.
Residential Renewable Energy Tax Credit
Established by The Energy Policy Act of 2005, the federal tax credit for residential energy property initially applied to solar-electric systems, solar water heating systems and fuel cells. A taxpayer may claim a credit of 30% of qualified expenditures for a system that serves a dwelling unit located in the United States that is owned and used as a residence by the taxpayer. Expenditures with respect to the equipment are treated as made when the installation is completed. If the installation is at a new home, the “placed in service” date is the date of occupancy by the homeowner. Expenditures include labor costs for on-site preparation, assembly or original system installation, and for piping or wiring to interconnect a system to the home. If the federal tax credit exceeds tax liability, the excess amount may be carried forward to the succeeding taxable year. The excess credit may be carried forward until 2016, but it is unclear whether the unused tax credit can be carried forward after then.

Residential Renewable Energy Tax Credit
A taxpayer may claim a credit of 26% of qualified expenditures, after deducting incentives, with no upper limit for a system that serves a dwelling unit located in the United States that is owned and used as a residence by the taxpayer. Expenditures with respect to the equipment are treated as made when the installation is completed. If the installation is at a new home, the “placed in service” date is the date of occupancy by the homeowner. Expenditures include labor costs for on-site preparation, assembly or original system installation, and for piping or wiring to interconnect a system to the home. If the federal tax credit exceeds tax liability, the excess amount may be carried forward to the succeeding taxable year. The excess credit may be carried forward until 2019, but it is unclear whether the unused tax credit can be carried forward after then.
