Abstract

The article investigates hot water production by cooling a photovoltaic panel in a PV device. For this purpose, a parallel-channel polycarbonate heat collector was installed on the back surface of the PVT. The results obtained based on mathematical modelling of PVT thermal parameters are presented in the article. Mathematical modelling was performed based on Comsol multiphysics 6.1 integrated software. In mathematical modelling, the dependence of thermal energy obtained from PVT on radiation intensity, temperature and speed of cooling water was studied. Mathematical modeling results were compared with experimental results. According to the results of mathematical modelling, the maximum value of PV surface temperature was 47.6oС in summer when the water speed was 0.001m/s. In the summer season, the results of the experiment conducted on the PVT device and mathematical modelling were compared. The results of experiments and mathematical modelling showed that the temperature of hot water difference by 2oС. It was determined that 41.4 liters of hot water per hour is obtained from the PVT device.
