Itochu Begins to Sell Home Energy Storage Systems in JapanChisaki Watanabe
Itochu Corp., a Japanese trading company, will begin sales of energy storage systems this month.
The product, with a capacity of 7 kilowatt hours, can store solar power generated from rooftop panels; it can also draw electricity from the grid at night, when power rates are cheaper, for use during daytime, Itochu said in a statement.
The device, to be sold for 2.4 million yen ($20,000), can store about 60 percent of the electricity an average household needs a day, according to the statement.
The system incorporates lithium-ion batteries made by Sony Corp., the Nikkei newspaper reported earlier today.
