Japan's Sunshine Project. Solar energy R and D program

Abstract

This paper explains the Sunshine Project and its solar energy R and D program. The solar energy is poured into the earth at 1.04 x 10{sup 17} kcal per hour, while the energy consumption of the world in 1970 is equivalent to 30 minutes of the solar energy. It is infinite compared to fossil fuel and clean, with no extreme partiality by areas. Its problem in utilization, however, is the low energy density of 1 kw/m{sup 2} and unsteady supply caused by weather conditions, which raises difficulties in matching energy demand. These demerits and low competitiveness in cost must be overcome through R and D. Under the Sunshine Project, the solar energy utilization is in progress in the areas of thermal utilization in a building, solar thermal power generation, and photovoltaic power generation. The budget was 9.6 billion yen for fiscal 1980 and 8 billion yen for fiscal 1981. Since fiscal 1980, emphasis has been placed particularly on photovoltaic power generation. The experimental production of solar cells of 500 kW/year is scheduled as a target through fiscal 1981-82. Four demonstration plants and two central distributing substations for photovoltaic power generation are planned to be built by fiscal 1985. Also to  More>>
