Abstract—In order to obtain the optimal design of solar energy system, the data of solar radiation should be provided. In this study, an estimation model of monthly solar radiation in Japan is developed using artificial neural network (ANN). The purpose of this study is to provide an accurate model to estimate the solar radiation, especially for the location where measured data is not available. The structure of ANN is constructed using geographical and 6 years-meteorological data between 2011-2016. The model has been validated by comparing the estimation results with measured solar radiation data on five different stations in 2017. Considering relatively small mean absolute percentage error (MAPE) and root mean square error (RMSE), it is believed that the proposed model could accurately predict the monthly solar radiation, which further could be used to obtain optimal design of solar energy system in Japan.
