The optimal temperature range for solar panels is typically between 15°C and 35°C (59°F to 95°F). . When you install solar panels at home, you expect them to be around for a long time. At least their expected lifespan of 25 years. This is. . To test the rated maximum output of solar panels, they are measured under the condition of 25 degrees Celsius (or 77 degrees Fahrenheit), while 1,000 watts of light per square meter shines on them. While these Standard Test Conditions (STC) are a little unrealistic, their purpose is to make sure. . Solar panels are power tested at 25 degree Celsius, so the temperature coefficient percentage depicts the changes in efficiency as it goes up or down by a degree. According to the manufacturing standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels.
