Fiscal 1976 Sunshine Project result report. Research on solar energy system (weather survey); 1976 nendo taiyo energy system no kenkyu seika hokokusho. Kisho chosa

Abstract

This report describes the fiscal 1976 research result on weather survey for solar energy systems. Study was made on preparation of the global solar radiation (GSR) map of Japan. To obtain the estimation equation of GSR based on related weather data, analysis was made on data at A type GSR observation sites and related weather data. As some factors effective for estimating monthly mean GSR, a relative sunshine duration, snowfall index (ratio of days more than 10cm in snowfall) and solar altitude index (sine of solar altitude at culmination hour) were selected. The estimation equation was prepared on the basis of these above factors. GSR was affected by relative sunshine duration exceedingly, snowfall by 12%, and solar altitude difference by 6% within an error of 5%. The monthly and annual GSR maps were prepared every site by the above calculation. The continuous observation results in Kagoshima and Fukuoka by recording direct pyranometers are presented. Scattered solar radiation is defined as the difference between simultaneously measured GSR and direct solar radiation. Weather data preparation in Fukuoka for design of solar cooling/heating and hot water supply systems is also described. (NEDO)
