Keywords: Manufacturing industry Renewable Energy 

Sekisui Chemical Co. Ltd., a Japanese company that manufactures plastics, urban infrastructure products and houses, announced on April 23, 2007 that by the end of March 2007 it had installed over 10,000 photovoltaic (PV) electrical generation systems when doing renovations of Sekisui-built houses. It credits this achievement to the company's active efforts to encourage customers to install PV systems when renovating their homes. This achievement is a record in Japan's housing industry. These PV systems generate an output of 41,000 kilowatts, resulting in a reduction of 12,000 tons of CO2 emissions.

The company started selling new houses equipped with PV systems in 1998 and installing PV systems in existing houses in 2000. The cumulative number of the PV systems installed in new and existing houses combined totaled 57,000 as of the end of March 2007. The percentage of the new houses with a PV system among the total newly built houses reached 55 percent in fiscal 2005. The average generation capacity increased to 4.3 kilowatts in the same year. During fiscal 2005, the company installed PV systems in 6,380 new and 1880 existing houses, or 8,260 houses in total. The figure accounted for about 11.5 percent of the total PV systems installed in fiscal 2005 in Japan.

According to a company survey of PV users of renovated houses, when asked about the benefits or reasons for satisfaction due to introduction of a PV system, the most popular answers were "environmental contribution" and "saving on utility costs." Satisfied users accounted for 48 percent of owners who had installed only PV systems, 73 percent for PV and electric water heaters, and 74 percent for PV and heat-pump water heaters.
