In the conditions of the modern energy crisis, the need for cheap energy sources is growing. Solar energy is a good and affordable alternative to current fuels, leading to increased construction of photovoltaic systems. The technologies used in solar energy are generally oriented towards the production of heat or electricity. The most important element of a solar system is the photovoltaic panel. It converts solar radiation into heat or electricity. The quality of the entire system and the amount of energy received depend on its efficient and reliable operation. There is a wide variety of materials, sizes and characteristics of photovoltaic panels on the market. It is this competitiveness between different types of photovoltaics that is one of the main reasons to look for the optimal technical and investment solutions for each photovoltaic project. This necessitates the creation of adequate mathematical and simulation models, through which preliminary research and analysis can be done.

In the present work, a simulation model of a photovoltaic panel is proposed in a Matlab/Simulink environment, which enables a preliminary analysis of its characteristics and an assessment of the optimal configuration of panels according to the specific project.
