In photovoltaic panels, panel surfaces are used with different designs to reduce losses from heating cooling and analysis of the results

In this thesis, it has been tried to cool the photovoltaic solar panels with the help of compressed steam on the back surface of the panel in order to reduce the heat-related losses and increase the panel efficiency. The values obtained by cooling the lower surface temperatures of the panels with compressed steam were measured and the data obtained were compared. Time-dependent temperature changes of the outdoor environment, solar radiation values and ambient conditions were measured. The results of the analysis of the obtained findings were examined in terms of yield mobility on the panel. Three 105W PV panels were used for the experiment. The module is cooled by compressed R600 gas with the help of a compressor in a copper pipe mounted spirally on the back surface of the three panels. The back surface of the module two panels was cooled only in case of water, while a module panel was left blank for reference purposes and to monitor the status of a panel in ambient conditions. Three different surface temperatures, ambient temperature and input and output temperatures placed on the panel surface were made and the power, current and volt values that occurred depending on time were recorded. According to the results, the maximum power ratios of all panels used in the experimental setup were determined beforehand. As a result of the test analysis, when the data of the panel with the cooling device and the empty panel are compared, it was found that there is an excess of 5.73% power generation in the panel where the cooling is done. When we compare the power output of the empty panels, the cooled panel produced 0.5W less power on average throughout the day. Although all three panels have the same characteristics, the differences have shown their effect as a result of the experiment. As a result of the calculations, while the electrical efficiency was 9%, the efficiency in the cooled panel was 7.9%. In the experiment, the cooling module three, the average temperature of the whole day was 33ºC, while the average temperature of the reference panel remained at 40ºC. In the study, the panel was cooled to 14ºC and this temperature difference can be increased if desired. For the module, which is cooled at 25ºC close to the ideal operating temperature, the panel back surface temperature range is kept constant at 30ºC, and the amount of power produced by the panel is observed. The amount of energy consumed by the compressor, which is a cooling element, for three hours in total was found to be 0.319 kWh. A 40W panel will be sufficient to meet this amount of energy consumed. In our study, the cooled module completely covered the back surface of the panel no. 3 with water and cooled the entire surface area equally. Due to the fact that this cooled surface area is equal, compared to other studies, the entire surface area is cooled equally, except for the areas where the cooling pipes come into contact. Thus, the panel has been increased efficiently.
