The Effect Of Pollution On Photovoltaic Panels Under Climate Conditions In Hatay

Abstract

In this study, the effect of pollution on monocrystalline and polycrystalline PV panels on short circuit current and open circuit voltage was investigated by external experiments. Experiments were carried out under climate conditions in Hatay province for 210 days from October 2019 to May 2020. In the study, 2 pieces of 45 W power monocrystalline PV panels and 2 pieces of 50 W power polycrystalline PV panels were used. PV panels were placed in two groups as manuelly cleaned and uncleaned on the tile roof. One of the monocrystal and polycrystalline panels was cleaned manually for regular periods, while the others were not cleaned except rain. Short circuit current, open circuit voltage, panel surface temperature and radiation values were measured for each panel at certain times during the day, in the morning, at noon and in the evening. In addition, ambient temperature and humidity values were measured and recorded. Environmental factors have been found to affect the short circuit current of the panels, not significantly affecting the open circuit voltage. It has been practically tested that manually cleaned panels have higher short circuit current values than uncleaned panels. Therefore, it has been calculated that cleaning the panels periodically will significantly increase the electricity production in powerful solar power plants. The data obtained as a result of experiments are modeled with artificial neural networks.
