Toshiba Corporation recently won a major contract to develop a mega solar photovoltaic power generation project for Hokuriku Electric Power Company under which Toshiba's system will be installed in the Shika Photovoltaic Power Station. The plant is expected to generate a total capacity of approximately 1 megawatt (MW). The order is the seventh that Toshiba has secured for a multi-MW PV project, and positions the company as supplier of almost half the mega solar power plants ordered by electricity utilities in Japan. Construction will start in November and the plant is scheduled to come on line in February 2011.
Toshiba was selected as prime contractor for development of the Shika plant, and will be responsible for all engineering work prior to the start of construction, the procurement of major equipment and components, and plant construction. The variable output of the photovoltaic cells will be converted to clean AC by integrated 250kW output power conditioners developed by Toshiba Group. A conversion efficiency of 97.5% assures that the power conditioners are the world most efficient in their class, and the industry's highest class for power conditioners installed in a mega solar photovoltaic project. The plant will also be equipped with highly efficient multi-crystal photovoltaic modules from Kyocera Corporation.
