Abstract

In this paper, photovoltaic cell single diode detailed model is developed and simulated. Entire system parameters in the model are taken into account. To determine the model parameters based on datasheet values and analyze the model, MATLAB system function (S-function) feature is preferred. S-function is used to obtain the photovoltaic cell discrete and applicable model in real system to be able to use in an embedded system. Necessary mathematical equations belong to the photovoltaic cell model are converted to discrete form and are written in S-function with C codes. Also, the simulation of the photovoltaic cell model is realized by using MATLAB S-function feature. To analyze and verify the validity of the presented model, I-V and P-V characteristic curves obtained from S-function are compared with datasheet characteristic curves of two commercial solar panels which are Kyocera KC200GT and Siemens SP75. The proposed model can be applied to any brand of photovoltaic panel by setting the parameters properly using datasheet values.
