South Carolina Incentives for Solar Energy

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. Additionally, the combination of these programs and the available south carolina solar tax incentives has significantly increased the adoption of solar technology across the state. Homeowners are not only reducing their utility bills but also contributing to a more sustainable energy future. As awareness of these benefits grows, more residents and businesses are expected to invest in solar solutions.

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. This policy not only incentivizes the growth of the solar industry within the state but also enhances the appeal of solar energy benefits for homeowners. By ensuring that solar generators are compensated at full retail value, residents can see a quicker return on their investment. Additionally, this legislative support fosters a more sustainable energy landscape, paving the way for a cleaner future.

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

• 25% tax credit for residential and commercial sectors
• Applies to solar thermal and solar electric systems
• Up to $3,500 a year, or 50% of taxpayer’s liability, whichever is less.
• Excess credit can be carried forward for 10 years.
