Federal Solar Incentives: The Investment Tax Credit (ITC)
The most significant financial incentive for homeowners nationwide is the federal Solar Investment Tax Credit (ITC). This is a dollar-for-dollar credit that directly reduces the amount of federal income tax you owe.
- Credit Amount: For systems installed between 2022 and 2032, the ITC allows you to claim 30% of the total cost of your solar energy system.
- Impact: On a $20,000 solar system, the 30% ITC provides a $6,000 credit, effectively lowering your net cost.
South Carolina’s State & Local Solar Incentives
South Carolina’s primary incentive is its own generous state tax credit, which can be combined with the federal credit for massive savings.
Name of Incentive | Type | Description | Key Details | Estimated Cash Value |
Federal Solar Tax Credit | Federal Tax Credit | A 30% credit on the total cost of your system against your federal income taxes. | The most significant financial incentive available. | $4,200 – $7,800 |
SC State Solar Tax Credit | State Tax Credit | A 25% credit on the total cost of your system against your state income taxes. | One of the best state tax credits in the country. | $3,500 – $6,500+ |
Property Tax Exemption | Local Tax Exemption | A local-option exemption on the value added to your home by a solar system. | Your property taxes may not increase. | Varies (By locality) |
Net Metering | Utility Bill Credit | Earn credits on your utility bill for excess electricity your system sends to the grid. | Maximizes the value of every kWh you produce. | Varies |
South Carolina Solar Energy Tax Credit
- How it Works: This powerful state-level tax credit allows you to claim 25% of your total solar system cost on your South Carolina state income tax return. This is in addition to the 30% federal tax credit. There are some limitations on how much you can claim per year, but you can roll over unused credits for up to 10 years.
- Impact: This is an incredible benefit that few states offer. On a $20,000 system, this provides a $5,000 state tax credit. When combined with the $6,000 federal credit, a total of $11,000 in tax credits has reduced the net cost of your system from $20,000 to just $9,000.
South Carolina Property Tax Exemption for Solar
- How it Works: South Carolina state law allows individual cities and counties to offer a property tax exemption for the value added by a solar system.
- Impact: In participating localities, this is a significant long-term benefit that saves you hundreds of dollars every year. The best way to get clear information on your specific locality is to work with a qualified local installer.
Utility-Specific Solar Programs in South Carolina
Net Metering
- How it Works: Net metering is a critical policy that ensures you get full value for every kWh your system produces. When your panels generate more power than you are using, the excess is sent to the grid, and you receive a credit on your bill from your utility (like Duke Energy or Dominion Energy).
- Impact: Net metering maximizes your bill savings and is the foundation of the financial return for solar in South Carolina.

Understanding the Full Cost of Solar
To appreciate how these powerful incentives work, it’s important to understand the total cost of a solar project they are designed to reduce. A complete solar installation includes panels, inverters, racking, and professional labor, all of which factor into the final price that is eligible for both federal and state tax credits.
