New Approach to Establish a Clear Sky Global Solar Irradiance Model

Abstract


Prediction of Global Solar Radiation of a given location is useful to obtain the correct design of solar equipments in the case of a clear sky conditions. We have developed a new approach to establish a GSR model using 10 years of measurements. This model allows the prediction of GSR to any a given clear day of the year. Results show that our model predicts the daily GSR with R of 0.982 and MBE of 7.937. In addition a good correlation between daily average values of the measured and predicted GSR is found (0.940 for R, 2.711 % for MAPE, 20.9 for RMSE and 2.727 for MBE).
