Japan's First Solar PPA Service Utilizing Chalcopyrite Solar Cells Launched

Tokyo Century Corporation, JFE Engineering Corporation, and Urban Energy Corporation have launched a solar PPA service in Myoko City, Niigata Prefecture, starting May 1, 2026. Utilizing Niigata Prefecture's subsidy program, the project involves installing chalcopyrite solar cells at the Myoko Clean Center to supply electricity to public facilities within the city. Chalcopyrite is gaining attention as a next-generation lightweight and flexible solar cell, marking the first such initiative for a municipal PPA project in Japan. Tokyo Century handles project development and finance, JFE Engineering provides technical support, and Urban Energy manages power supply. To address challenges in snowy regions, such as reduced power generation and roof load, this technology was selected for its high performance in cloudy conditions and lightweight design. Furthermore, its flexibility allows for installation on curved, arch-shaped roofs. Through this project, the companies aim to establish a new PPA model using next-generation solar cells and contribute to a decarbonized society.
