The Rapid Payback Period
In states without SREC programs, the ROI is based purely on avoiding utility bills. In D.C., you achieve "dual value." First, you wipe out your expensive Pepco bill through net metering. Second, you sell the highly valuable SRECs your system generates. When you combine this massive income stream with the 30% Federal Tax Credit, the average payback period for a D.C. solar system is astonishingly fast—often dropping to between 3 and 6 years. After this breakeven point, your system produces decades of pure profit.
