South Carolina Incentives for Solar Energy

Renewable Energy Policy in South Carolina

The adoption of solar energy in South Carolina has been relatively slow, but that is soon to change as recent legislation is spurring several strong utility incentive programs. In July 2014 South Carolina mandated the creation of a voluntary Distributed Energy Resource Program, with set targets for generation capacity from renewable energy sources. In response, the major utilities have created incentive programs for their generating customers. These newly introduced incentives, along with the Federal tax credit and South Carolina’s tax credit, make solar energy a very favorable investment for home and business owners at this time.

Furthermore, South Carolina also addressed net metering policy in its 2014 legislation, establishing full retail value  for electricity that solar generators deliver to the grid  through 2025.

In addition to significant federal incentives. South Carolina residents and businesses may be eligible for the following incentives:
