Solar Incentives

There are several tax incentives and rebates offered by the state, the federal government and some utility companies that can make going solar even more affordable.

Federal Tax Credit

The federal government provides all homeowners and businesses with a solar tax credit. This credit allows you to deduct 26 percent of the total cost of your solar energy system from your federal taxes. Known as the Investment Tax Credit (ITC), this credit applies to both residential and commercial systems. There is no cap on the total credit you can receive. However, to capitalize on this tax incentive, it’s important to act quickly. The future of this tax credit is uncertain, but once you have filed for it, you are guaranteed the opportunity to take the credit in the amount for which you filed, even if the incentive rate changes while you claim the entire credit amount. 

South Carolina Tax Credit

In South Carolina, the state offers a tax credit of 25% of the total cost of your solar energy system. The state limits the amount you can claim in each year to $3,500, or half of your state tax liability, whichever is lower. You have up to 10 years to claim the full 25% credit.
