Estimation of solar power generation using weather satellite images

Abstract

Solar power generation has many advantages over other renewable energy, while there are many problems in order to spread it. In addition to the improvement of power generation efficiency and the reduction of manufacturing cost, power generation prediction is important for spreading it. Although an amount of power generation is approximately proportional to the volume of sunshine duration in the region, prediction accuracy would be significantly reduced in areas such as AMeDAS data is not accumulated. In this study, we developed a method to estimate the volume of sunshine duration using weather satellite images. We devised a formula of the estimation model for Miyazaki city as an example. As a result, we confirmed the possibility of estimating the volume of sunshine duration using weather satellite images.
