Energy-storing Products

Energy-storing products, in which power is stored and used when needed, play an essential role for stable power supplies of power generation through renewable energy such as solar and wind power.

In December 2010, we provided a photovoltaic power generation system and a lithium-ion battery system for power storage to a convenience store, LAWSON, INC., in Kyotanabe City, Japan. The power generated by the solar panels supplements the energy requirements of the store during peak time. By storing less-expensive, night-time power for use during the day, the systems reduce the use of commercial power and lessen costs. Additionally, the energy stored in the battery system can be used as a backup power supply in times of emergency.
