Home storage systems have been considered an ‘early adopter’ market in many parts of the world, perhaps more important as a way that individuals can control their own green energy use and save energy than as a means of generating big money returns.

Softbank Energy and Kyocera, two major names in Japan’s solar energy industry, are partnering with utilities, grid operators and other stakeholders to execute virtual power plant (VPP) projects backed by the government.

Kyocera is targeting the German market for self-consumed solar electricity, with the Japanese company preparing to launch a home energy storage system in May.
