Research highlights the significant benefits of regular cleaning: A study by the National Renewable Energy Laboratory (NREL) found that cleaning solar panels in high-dust areas can increase efficiency by up to 35%. In regions with heavy bird activity, regular cleaning improved. . Solar panels work by absorbing sunlight and converting it into electricity. When they are covered in dust, pollen, or grime, less sunlight reaches the photovoltaic cells, leading to a significant drop in efficiency. Studies have shown that dirty solar panels can lose 15-25% of their energy output. . Studies show that dirty panels can lose anywhere from 15% to 25% efficiency, depending on the location and environmental conditions. Dust and Dirt: Common in urban and rural areas, reducing sunlight absorption.

As the temperature increases above 25°C, solar panels experience a decrease in efficiency. Solar modules like PERC, TOPCon, IBC, and HJT lose efficiency when it gets hot. For example, if a solar panel has an efficiency rating of 20%, it means that 20% of the sunlight hitting the panel is converted into electrical energy, while the rest is reflected or lost as. . As the temperature of the cell increases, the efficiency of the photovoltaic conversion process decreases. This is because the electrical properties of the semiconductor materials used in PV cells, such as silicon, are temperature-dependent. The efficiency of a solar panel is typically expressed as a percentage and. . The negative effect of the operating temperature on the functioning of photovoltaic panels has become a significant issue in the actual energetic context and has been studied intensively during the last decade.
