Solar energy is an inexhaustible, clean and sustainable energy source, but only a small amount is used to directly power human activities. Different forms of renewable energies have been discussed along with the most important one, the solar energy. The solar module is the equipment to converts the sunlight into the electricity directly. The modeling of PV (photovoltaic) systems is very crucial for designing the system for practical applications. This book presents a PV array model developed using Matlab/Simulink where the effect of solar insolation and PV array temperature on commercial PV modules have been studied through the simulated P-I, I-V and P-V output characteristics. The proposed model facilitates simulating and monitoring the dynamic performance of PV-based systems. Therefore, the accurate solar module model established in this book can be applied to the simulated photovoltaic generation system in order to precisely simulate and predict the characteristics of power generation for real photovoltaic system. In summary, this book is a valuable asset for every solar engineer. It provides an step-by-step information about the MATLAB Modelling of Solar PV Panel.
