No. 115: Real estate companies focus on condominiums with a photovoltaic generation system (July 28, 2010)

Major Japanese real estate companies will start building condominiums with a photovoltaic generation system. JX Energy will build a six-storied condo designed for some 100 households. It will set about 500 panels on its rooftop and allocate panels with the generation capacity of 1.2 kW to each apartment. Surplus power will be sold to electric power companies. Each household is estimated to decrease the electricity charge by 4,000 yen per month. ORIX Real Estate will install photovoltaic general panels on the rooftop of a three-storied condo and allocate 12 panels to each household. Each household will have a generation capacity of 1.02 kW, and it will supposedly get monthly revenue of 2,000 yen on average by selling surplus power. The unit price of surplus power purchased by the electric power company doubled last November. This revision made real estate companies focus on building condos with a photovoltaic generation system.
