Mar. 03, 1978 - A one kilowatt array of photovoltaic cells that converts solar energy directly into electrical energy has been built as part of the Varian Associates solar energy research program. Headed by scientists Larry James, Ron Moon and Hugh VanderPlas (left to right), the program has demonstrated efficiencies up to 23.3 percent for the conversion process using gallium arsenide cells. New contracts awarded to the company by the Department of Energy call for further efficiency improvement and construction of an experimental solar conversion, 50-kilowatt power plant. The plant, to be ready in early 1980, will be built in conjunction with Pacific Gas and Electric Company at its San Ramon substation across the bay from San Francisco
