What is PD IEC/TS 62782-Photovoltaic (PV) modules about?
PD IEC/TS 62782 is a technical specification that provides a test method for performing a cyclic (dynamic) mechanical load test in which the module is supported at the design support points and a uniform load normal to the module surface is cycled in alternating negative and positive directions.
This test can be performed at any module temperature within the normal operating temperature range. Since the results have been determined to depend on the module temperature during the application of the load it is critical to maintain the module at a constant temperature during the performance of this test.
This technical specification has historically been applied to rigid modules. It cannot be applied to flexible modules unless they are designed to be mounted in a rigid manner. In which case, the cyclic (dynamic) mechanical load test can be applied to the flexible module in its rigid mounting system.
Who is PD IEC/TS 62782-Photovoltaic (PV) modules for?
PD IEC/TS 62782 on photovoltaic modules is useful for:
- PV module manufacturers
- PV power system manufacturers
- Photoelectric device manufacturers
- Solar energy engineering industry
- Product designers
- Quality assurance and testing personnel
Why should you use PD IEC/TS 62782-Photovoltaic (PV) modules?
Dynamic mechanical loads are generated by the movement of the means of transportation and during handling. Dynamic loads are always expressed as a multiple of gravity's acceleration.
The technical specification PD IEC/TS 62782 specifies a test method for performing a cyclic mechanical load test in which the module is supported at the design support points and a uniform load normal to the module surface is cycled in alternating negative and positive directions.
PD IEC/TS 62782 can be useful to evaluate if components within the module including solar cells, interconnect ribbons and/or electrical bonds within the module are susceptible to breakage or if edge seals are likely to fail due to the mechanical stresses encountered during installation and operation.
Compliance with best industry practices for photovoltaic modules with PD IEC/TS 62782 can help you evaluate the mechanical stresses that may occur during the implementation and operation of photovoltaic modules.
