[pdf] As the temperature of the PV cell increases, the open-circuit voltage decreases. . Cold Weather Maximizes Efficiency: Solar panels can exceed their rated output by 5-10% in cold conditions, making winter days with bright sunshine often the most efficient operating periods despite shorter daylight hours. This is because the electrical properties of the semiconductor materials used in PV cells, such as silicon, are temperature-dependent. At higher temperatures, the increased thermal energy in. . Photovoltaic modules are tested at a temperature of 25° C - about 77° F, and depending on their installed location, heat can reduce output efficiency by 10-25%. However, it's worth noting that solar panels still produce electricity even on hot days.
