South Carolina Net Metering

Roughly 76.09% of the electricity providers in South Carolina offer net metering to their consumers. South Carolina has good regulations in place for consumers who are interested in taking advantage of net metering with solar panels.

Energy Loss

South Carolina has 28 electricity providers who report energy loss during transmission activities. The average energy loss for these suppliers is 3.11%. With a nationwide average of 2.45%, South Carolina is the 23rd best state in the country.

Solar Taxes And Rebates

When it comes to stimulating personal solar, one of the government's easiest methods is tax and rebate related incentives. With over $2000 or 20% in tax credits for solar purchases, South Carolina has decent options for state solar tax credits. Offering no rebates for solar panel installs, the state currently is dropping the ball for its citizens who want to install private solar panels. The state of South Carolina offers no property tax exemptions to homeowners who install solar panels, making it less attractive for residents to do so. Homeowners in the state do not have access to a sales tax exemption when purchasing solar panels.

State Level Initiatives

Whether a consumer is able to easily find electricity options with renewable fuel sources is at least somewhat determined by initiatives at the state level. Many states require green fuel sources to be a percentage of the fuel used for electricity production by providers in the state. These guidelines are referred to as Renewable Portfolio Standards (RPS). The state of South Carolina does not currently have any standards set up that providers have to adhere to. Furthermore, there are currently no low income solar programs to assist low income families to install solar panels.
