Solar panels
Solar power in South Carolina is rapidly becoming competitive with grid electricity, due to the decrease in cost and the eight-year extension to the 30% federal tax credit, which can be used to install any size system.[1] South Carolina offers a 25% tax credit, meaning that 55% of the cost is covered through tax credits.[2][3]
South Carolina's largest solar installation was the 311 kW Grand Strand Solar Station array in Myrtle Beach, completed on April 18, 2011,[4] until December 2, 2011, when Boeing completed covering the roof of their 787 assembly building with a 2.6 MW solar array, sufficient for 20% of the building's energy use.[5][6]
