What is PD IEC/TS 62788-7-2-Accelerated weathering tests of photovoltaic modules about?
The IEC 62788 series covers various measurement procedures for materials used in photovoltaic modules.
PD IEC/TS 62788-7-2 is one of the parts of the series that defines test procedures to characterize the weatherability of polymeric component materials used in photovoltaic (PV) modules or systems. The methods in PD IEC/TS 62788-7-2 have been focused on polymeric back sheets and encapsulants, but may be applied to other materials; however, these were not verified as part of the preparation.
PD IEC/TS 62788-7-2 includes a suite of artificial weathering exposures, consisting of a steady-state application of simulated solar irradiance, temperature, and humidity conditions maintained at stable levels through the weathering test. Cyclic stresses, including thermal and wet/dry cycles are left for future specifications.
Who is PD IEC/TS 62788-7-2-Accelerated weathering tests of photovoltaic modules for?
PD IEC/TS 62788-7-2 on measurement procedures for materials used in photovoltaic modules useful to:
- PV module manufacturers
