Energy Self-Consumption House Verification Test to Start in Japan Next Month

Misawa_HomeMisawa Homes, Misawa Homes Institute of Research and Development Co Ltd (Suginami-ku, Tokyo) and Kyocera will start to jointly conduct a verification test of an energy self-consumption house, which preferentially uses electricity generated in house, by using a model house built in Nara Prefecture in October 2015.

Solarpanel_kyoceraThe energy self-consumption house is equipped with Kyocera’s solar power generation system (6.6kW) and lithium-ion (Li-ion) storage battery system (7.2kWh). And energy is optimally used by linking the two systems.
