This 48-panel, 12,240-watt system installed on a classic New England red barn, and the back of the farmhouse, is producing more than 13,100 kWh of electricity a year. That power is worth nearly $2,300 a year. The system also is earning almost $29,000 in SREC income over 10 years, and offsetting the amount of CO2 spewed by about 2 cars over an entire year. Those are numbers worth celebrating!
