Average system payback period

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. South Carolina offers a 25% tax credit, meaning that 55% of the cost is covered through tax credits.

South Carolina's largest solar installation was the 311 kW Grand Strand Solar Station array in Myrtle Beach, completed on April 18, 2011, 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.

I am claiming the 26% Federal Tax Credit (ends 2020) i

When you install your solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.

Most people are eligible to claim this credit (you must owe federal taxes to be eligible).
