South Carolina Solar Rebates And Incentives

South Carolina Rebates and Incentives Summary

South CarolinaAlthough South Carolina does offer some seemingly good incentives on paper, not enough renewable producers are able to fully take advantage of the few available incentives that can make or break green industry, primarily due to the lack of standards and legitimate regulation.

Utilizing the federal tax credits for solar and small scale hydropower installations is the leading way environmentally conscious power consumers are making good on their green investment. Also, buying into the non-profit Palmetto Clean Energy (PaCE) program is giving renewable producers a reason to rejoice, but consequently is taking away from the South Carolina Public Service Commission’s (PSC) mandated net-metering program, because of the vagueness of realistic incentives and benefits that investor owned utilities (IOU) are required to offer.

Without any kind of Renewable Energy Standard (RES) South Carolina has left themselves at a disadvantage to make their claim in the green revolution taking place across the nation. As compared to neighboring states, and the example of the nation’s leader in renewable industry, California, a RES may at first be controversial, but after a few years could be South Carolina’s golden ticket to a championship caliber green economy and busy local solar installers.

Building Energy Code

Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

Prior to 1997, South Carolina's local governments adopted and enforced the building codes. In 1997, the law required statewide use of the most up-to-date building codes, which then required the adoption and enforcement of the 1995 MEC (Model Energy Code). The MEC has since been published as the International Energy Conservation Code (IECC). On November 28, 2007, the
