Under the main contractor, we installed solar power generation facilities that use both rooftop (100 kW) and ground (500 kW) solar panels.
As power conditioners are placed in a dedicated enclosure, we installed power sources for rooftop solar panels together with four power poles and overhead wiring. In addition, because of the distance from the interconnection pole, we installed another four power poles to connect to the leading-in pole and fitted the overhead wiring.

As of 2021, we have the achievements of constructing projects 200 MW nationwide.

An actinometer, solar panels, and a thermometer are installed on the rooftop to measure the amount of insolation, the power output, and the temperature. The solar power generation visualization system displays these data, as well as the amount of power saved, both quantitatively and graphically on an in-store monitor via the Internet and the data can be monitored from the office.
The data displayed on screen are updated in real time and the store can effectively publicize the in-store power saving achieved by solar power generation. 

We have a significant achievements of installing self-consumption type power generation facilities by installing solar panels on the rooftops of own factories and warehouses.
