The test temperature represents the average temperature during the solar peak hours of the spring and autumn in the continental United States . According to the manufacturing standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels.
Test conditions are defined as 800W/ m² irradiance, 20°C ambient temperature and wind speed of 1m/ s with the PV module at a tilt angle of 45° and its back side open to the breeze (as opposed to conditions where panels are mounted on roofs where heat builds up under the panel).
The temperature of the solar panel’s cells plays a significant role in its efficiency. As the cell temperature rises, the efficiency tends to decrease. Therefore, STC specifies a cell temperature of 25°C to establish a reference point for performance evaluation. Air mass represents the path length of sunlight through the Earth’s atmosphere.
The STC test for solar panels involves subjecting the panels to specific conditions, such as a solar irradiance of 1,000 watts per square meter, a cell temperature of 25°C, and an air mass of 1.5. These standardized conditions allow for accurate measurement and comparison of module performance. What is STC efficiency?
The maximum temperature solar panels can reach depends on a combination of factors such as solar irradiance, outside air temperature, position of panels and the type of installation, so it is difficult to say the exact number.
When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F). Panels with a lower temperature coefficient, closer to zero, perform better in high temperatures.
