Solar Frontier announced today that it supplied 21.3 MW of its CIS thin-film modules for one of the largest megasolar (utility-scale) solar energy power plants in Yamaguchi Prefecture, Japan. The power plant, which came on stream in July 2014, is owned and managed by US Power Co., Ltd, a joint operating company set up by Ube Group and Showa Shell Sekiyu.
The US Power Plant is expected to generate about 25,010,000 kWh annually. This is equivalent to the amount of electricity used by about 6,900 households in Japan, and will reduce CO2 output by about 8,300 tons. The electricity generated at this facility will be sold to Chugoku Electric Power Company and has been approved for Japan’s solar energy feed-in tariff program.
Solar Frontier’s proprietary CIS technology delivers more kilowatt-hours per kilowatt-peak in real operating conditions than crystalline silicon. The performance of Solar Frontier’s CIS modules continues to be demonstrated worldwide. This project demonstrates continuing demand for Solar Frontier’s CIS modules in large projects. Supplied by Solar Frontier’s gigawatt-scale production facility in Miyazaki, Japan, the company can deliver consistent, durable and quality modules for large orders around the world.
