Standard test conditions (STC) – Definition, Glossary, Details – Solar Mango

Standard test conditions are defined as the solar irradiation of one kilowatt (kW) per square metre, a module temperature of 25 degrees Celsius and a solar irradiation angle of 45 degrees. The test gives the STC ratings. Standard Test Conditions create uniform test conditions which make it possible to conduct uniform comparisons of photovoltaic modules by different manufacturers.
