Abstract

The sun is an inexhaustible source of clean energy. For a long time, humans perceived the sun as a source of heat and light, without thinking of using it fully for their purposes. The worldwide solar photovoltaic (PV) market has been growing rapidly, with significant investments leading to increased capacity. Mathematical models are used to calculate solar radiation, taking into account various meteorological factors to predict solar energy generation. The construction of P-V curves helps understand the output of PV systems, crucial for optimizing energy conversion efficiency. The photovoltaic effect allows solar cells to convert light into electrical energy, highlighting the importance of understanding the relationship between current and voltage in solar panels. In this work, the mathematical model of PV is presented and the equations that describe the relation between PV and environment are presented. Finally, a complete model is designed in Matlab and the results are presented.
