Gov. Nicky Haley signed the net metering bill into law last year in South Carolina. This is making it possible for some homeowners to swap their power bill for a solar bill and end up owning their power within years. That’s right, no electricity bill, who wouldn’t want that. Net metering allows you to sell your excess energy back to the grid by day while overproducing and pulling what you need from the grid when the sun is down. This acts like an energy savings account between you and your utility.
