Add to ORKGThe aim of the thesis is to design a method of recycling / reutilization of photovoltaic panels at the end of their service life. In the theoretical part is introduced and described photoelectric effect, history, development, production methods and types of photovoltaic panels. Furthermore, the composition and structure of photovoltaic panels are discussed and the technologies currently used for recycling these panels for maximum energy savings are specified. The experimental part of the work is mainly focused on the development of a prototype device, which can measure the current efficiency of the used photovoltaic panels, based on a comparative method, and quickly determine in the field conditions the future reusability of the solar panel
