Analysis and modeling of different transient cases occuring in solar panels

The aim of this study is to observe the responses of different types of solar panels to various transient conditions. In the experiments, 25-watt monocrystalline and 25-watt PERC monocrystalline solar panels were used. Transient conditions such as artificial shading, rain, and wind effects were examined. For measuring these effects, electrical values were recorded using two handheld multimeters, solar irradiance with a solarimeter, airspeed with an anemometer, and ambient and surface temperatures and relative humidity with a temperature and humidity meter. A fan was used to create artificial wind. The experiments revealed that monocrystalline panels produced 2.5% more voltage during the day compared to perc panels, whereas perc panels generated 330% more voltage in the evening compared to monocrystalline panels. Considering the location of the panel installation, it was concluded that monocrystalline panels are more suitable for regions with high sunlight, while perc panels are more suitable for regions with irregular sunlight. The obtained data were modeled using artificial neural networks (ANN) techniques.
