No. 343: A new household photovoltaic generation system from NTT DoCoMo (November 5, 2011)

NTT DoCoMo will enter the the household photovoltaic generation market in alliance with electronics companies both at home and abroad. The initial system, which comes with a small solar battery and a storage battery, will be launched in 2012 for a unit price of less than 100,000 yen. It will be a portable system with a generation capacity of less than 1 kW. It can be used as an emergency power source for a PC and lighting in case of a power outage. The storage battery is detachable, and it comes with an end connection for charging a mobile phone. The new system will be sold through about 2,400 NTT DoCoMo shops across the country. 

Amid the growing concern over power saving, the company plans to open up a new market by integrating its excellent communication technology with a smartphone for the surveillance and management of power consumption in household. It further intends to develop software programs for the management of power consumption in households and remote areas alike. It has already developed a system to know power consumption in detail using a small-size power meter with a wireless communication function. In the future, the company will develop a large-scale photovoltaic generation system with housing makers and volume retailers of electric appliances. Ultimately, it wishes to establish a dominant position in the market of household energy management by dint of its excellent communication technology.
