BRITTANY WALKER (University of Colorado, Boulder, Colorado 80309), Andy Walker (National Renewable Energy Laboratory, Golden, Colorado, 80401). In 1979 a large 93 kW photovoltaic-diesel generator hybrid system was installed as the only source of power for Natural Bridges National Monument. As the components in the system have aged the performance of the system has declined by more than 50% despite its upgrade in 1992. Natural Bridges has enlisted the help of the . . .
