Comparison of PV estimation model with measured PV power output

This paper describes a comparison of proposed model with simulation software and measurement data of PV power plant in Cambodia. The proposed model is based on behavior of PV module at a particular site. The parameters which affected to PV power output as solar irradiance and module temperature were used as input in this model. Weight function technics were used to improve accuracy of single diode five parameters (1D5P). It was found that the proposed model can improve the accuracy of PV power output estimation model.
