※1 A state in which economic benefits can be achieved by introducing storage batteries. According to estimates by the Ministry of Economy, Trade, and Industry, this equates to less than 60,000 yen/kWh for commercial and industrial use and less than 70,000 yen/kWh for residential use. ※2 By including certain costs in the initial investment, it is possible to achieve maintenance-free operation for 20 years and guarantee battery capacity after 20 years. ※3 A simulation case involving the introduction of a new solar power generation system, our storage batteries, and EMS (Energy Management System) into a logistics warehouse.
