EXPERIMENTAL ANALYSIS OF SHADING IN PV PANELS

Abstract

The energy is an important issue that should be emphasized in terms of the development of countries. Population growth and the resulting increase in needs have also increased the number of studies on renewable energy. Solar energy stands as a renewable and environmentally friendly power source. Its significance in electricity generation is progressively growing, making research in this field increasingly crucial. Photovoltaic (PV) panels emerge as essential intermediary components in harnessing solar energy. PV panels have many advantages, the most important of which is that they use a clean, sustainable energy source. The efficiency of PV panels is a critical consideration as well.. The efficiency of PV panels depends on dust, humidity, pressure, dust, wind, rain, bird droppings, etc. seriously affects. In this experimental study carried out outdoors, PV panel cells were closed horizontally and vertically to create a shadowing effect and measurements were made. According to the measurements taken, the optimum power values for both the monocrystalline panel and the thin film panel decrease to 0.1 W, especially after 3 and 4 cells are turned off. Reliability analysis was performed on the Weibull distribution with the experimental results obtained. Measurements and analyzes have shown that the shading effect seriously reduces the efficiency of PV panels.
