Benefits of Using Green Energy
July 30, 2013 - 67 kW (STC rating) photovoltaic array at the Mesa Verde Visitor and Research Center in Montezuma County, Colorado. The array consists of 286 Schott Poly 235 watt solar modules (13.8% efficiency) wired in 22 series strings of 13 modules per string. Coupled with a micro-hydro system and solar water heating, the on-site renewable energy systems are capable of providing 95% of the building energy requirements. (Photo by Dennis Schroeder / NREL)
