Earth’s temperature is only getting warmer, and LONGi is testing its modules’ capacity to withstand extreme temperatures during product design and thresher verification phases.
The standard operating temperature of a PV module is higher than the ambient temperature. Under continuous exposure to extreme high temperatures, the temperature of a module at a solar power plant can reach 75°C or more, and the working temperature of its internal cells may be even higher.
Existing base testing parameters commonly set the maximum temperature for a PV module at 85°C, however, in some extreme conditions, its working temperature may exceed this level.
LONGi’s Hi-MO 5 module passed the stringent thresher thermal cycling testing and is the first to receive the associated IEC 62892 certification. LONGi high-efficiency modules have also completed IEC TS 63126:2020 testing.
