Energy has become an indispensable part of our lives today and our energy needs are increasing day by day with technological developments. In addition, the rapid depletion of natural resources and the deterioration of the ecological balance forced humanity to find and use new and clean energy resources. Renewable energy sources gained importance rapidly and dozens of studies were conducted on them. Photovoltaic panels are the basis of these studies, which started with the production of electricity from solar energy. Photovoltaic panels consist of many solar cells. The energy coming from the sun with photons is directly converted into electrical energy in these cells. The studies that started with the aim of generating electricity with photovoltaic panels were later developed to gain thermal efficiency in the same system and hybrid systems called Photovoltaic-Thermal were created. Photovoltaic-Thermal Systems (PV / T) transfers the thermal energy generated in photovoltaic panels to one or more fluids and aims to increase system efficiency by using the thermal energy generated during electricity generation. In this study, it will be investigated how the properties of glass, which is the first part of solar energy, affect the thermal and electrical efficiency of a PV / T system working with air and water fluids. Three glasses were selected in the system and experiments were conducted under similar outdoor conditions. The experiment data were transferred to the computer environment by means of a program specially written for the system and daily. The electrical and thermal efficiency of the transferred data was calculated by mathematical formulation, and it was investigated how glasses affect the efficiency of the system. This system can be further developed and used in daily use in hotels and dormitories. The study will also trigger the use of alternative glasses with different properties in the system and will take a step towards increasing efficiency.
