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.
