However, the efficiency of photovoltaic panels decreases significantly with rising temperatures, posing a critical challenge in optimizing their performance. This thesis studies an innovative cooling strategy for photovoltaic panels using phase change materials (MCP). The study focuses on the performance of a single MCP which is the RT-25, evaluating its effectiveness in maintaining optimal temperatures of photovoltaic panels. In addition, the impact of fins on thermal regulation efficiency is explored by integrating fins into the MCP-based cooling system. This research contributes to the field of renewable energy by providing a viable solution to improve the performance and sustainability of photovoltaic systems, thus promoting the adoption of more efficient and sustainable energy practices.frL’énergie solaire, panneaux photovoltaïque, convection naturelle, ANSYS FluentThesis
