House was built in 1903 when the city installed a electric steam generator. We installed solar hot water heater system with a PV module to power the circulating pump. In 2005, we installed a 2.6 kW grit-tied photovoltaic system for net metering. Then we installed a 700 watt stand-alone battery PV system for emergency power. Other solar items were install, like solar water distiller, PV power shed fans, security lighting and other consumer items. Also, PV charging of electric vehicles.
