CIS Photovoltaic Production Plant in Miyazaki


Solar Frontier K.K.




Miyazaki, Japan

Scope of Work: 


Year of Completion: 


New partnership launched with Solar Frontier K.K.

Chiyoda has completed an engineering, procurement and construction (EPC) project for Solar Frontier’s Kunitomi Plant (or the Third Miyazaki Plant), a world-class manufacturing plant of CIS thin film modules.

The Kunitomi Plant has been designed to operate with a production capacity of 900 megawatts. Solar Frontier launched commercial production using a few production lines in February 2011, and it has since been pursuing production automation processes with larger production facilities.

A ceremony was held to mark the completion of the Kunitomi Plant in the month following the Great East Japan Earthquake. Among the guests at the ceremony were representatives from the Ministry of Economy, Trade and Industry, Miyazaki Prefecture, Miyazaki City, New Energy and Industrial Technology Development Organization (NEDO), Development Bank of Japan (DBJ), Solar Frontier K.K., and Showa Shell Sekiyu K.K., along with members of the media from all over the world. During the ceremony, participants delivered warm messages expressing their wishes for a speedy recovery from the disaster.

Under the EPC project, Solar Frontier K.K. and Chiyoda have continued to bolster our partnership, taking steps to jointly develop mega solar systems that are capable of utilizing the advantages of the CIS thin film solar batteries developed by Solar Frontier K.K.
