This master thesis analyses the parameters that affect the operation of the photovoltaic system, specifically solar power plants. In today's world, there is a growing emphasis on renewable energy sources to reduce dependence on fossil fuels and mitigate negative environmental impacts. Solar power plants play a crucial role in this transition towards a sustainable energy future. The thesis examines how various parameters affect the performance of photovoltaic systems, investigating the impact of shading, orientation, panel geographical positioning, weather conditions, and panel maintenance on energy production. Through a projection of power plant production on the roof of a multi-story building, these analyses are applied in a practical context. As part of the thesis, the current status and prospects of renewable energy sources in Croatia are analyzed, with a focus on solar energy. The potentials for further development of solar capacities are identified, taking into account social, technical, and economic factors. The thesis also explores possible enhancements to photovoltaic system technology. Innovative technologies, performance monitoring techniques, and the integration of solar systems into existing energy grids are studied to achieve greater efficiency and sustainability. In conclusion, this thesis recognizes the importance of solar power plants as key factors in the transition towards a sustainable energy future. Through parameter analysis, production projection, consideration of prospects and enhancements, the study highlights their significance. The final part of the thesis presents a methodological section in the form of teaching preparation, providing practical guidelines for further educational and research activities in this field.
