Renewable energy is expected to replace thermal power by fossil fuel for reduction of green gas emission, air pollution and energy-security. Especially solar power generation is expected because it is got anywhere and its cost has reduced recently. But it is got only in the daytime on sunny days. Furthermore the amount, the time period it can get depends on seasons, weathers. Storage battery is essential for accumulating overpowered electricity and emitting it after sunset. The peak electricity demand is important factor to design electricity power plants. There are large electricity demands in summer and winter by air-conditioning. It is important to replace them by solar power with storage battery Building Research Institute in Japan has a demonstration house, which has solar power generator and storage battery combined system. The authors have measured how this system worked with air-conditioning electricity demand in summer and winter. And the authors applied these results to the actual electricity demand in Tokyo Metropolitan area. If solar power generator is combined with storage battery, it could cover air-conditioning cooling demand completely. In winter, peak electricity is high in morning and evening. So solar power could not mitigate electricity supplying demand in winter directly. But it is expected to supply electricity for a whole day, combined with storage battery.
