These homeowners put solar on their house and two out-buildings, which all have standing-seam metal roofs. Between electric bill savings and SREC checks, they are reaping about $350 in solar benefits per month. The system has SunPower 327-watt panels and SolarEdge inverter technology. (The house is so interesting we included a few pre-solar photos for you.)
