KYOCERA Collaborating with Mitsui and SB Energy to Construct 19.6MW ‘SoftBank Izumiotsu Solar Park’ in Osaka, Japan

October 10, 2013
The Kyocera Group’s (President: Goro Yamaguchi) subsidiary in charge of sales of solar products and services in Japan, Kyocera Solar Corporation (headquarters: Kyoto; president: Seiji Goto; herein “KSC”) and Mitsui & Co., Ltd. (headquarters: Tokyo; president: Masami Iijima; herein “Mitsui”) have agreed to collaborate on the operation of the SoftBank Izumiotsu Solar Park, a 19.6-megawatt (MW) solar power plant being built by SB Energy Corp. (headquarters: Tokyo; CEO: Masayoshi Son; herein “SB Energy”) in Osaka Prefecture, Japan.

The SoftBank Izumiotsu Solar Park will be the largest* solar power installation in Osaka Prefecture and is being built on approximately 25 hectares of prefectural government land. Approximately 80,000 Kyocera solar modules will be used for the 19.6MW project, which is expected to generate roughly 20,680MWh of electricity each year ― the equivalent amount to power roughly 5,700 typical homes. Izumiotsu Solar Park Corp. has been jointly established by Mitsui, SB Energy and KSC to manage the project, with the solar park set to go online in July 2014.

Mitsui, SB Energy and KSC will continue to promote the expanded use of clean energy by building and operating large-scale mega-solar power plants.
