PV module Robustness Terminations testing equipment purpose It's to determine that the terminations and the attachment of the terminations to the body of the module will withstａnd such stresses are likely to be applied during normal assembly or handling operations
PV module Robustness Terminations testing equipment types Three types of module terminations are considered Type A : wire or flying lead Type B: tags, threaded studs, screws, etc Type C : connector
PV module Robustness Terminations testing equipment procedure Preconditioning : 1h at standard atmospheric conditions for measurement and test
Type A terminations Tensile test : as described in IEC 60068-2-21, test Ua, with the following provisions : ---all terminations shall be tested ---Tensile force shall never exceed the module weight Bending test : as described in IEC 60068-2-21 , test Ub , with the fllowing provisions , ---all terminations shall be tested ---method 1-10 cycles (1 cycle is 1 bend in each opposite direction)
Type B terminations Tenwile and bending tests: a) for modules with exposed terminals , each termination shall be tested as for type A terminations b) if the terminations are enclosed in a protective box, the following procedure shall be applied:
Torque test : as described in IEC60068-2-21 , test Ud with the fllowing provisions : --all terminations shall be tested -- severity 1
The nuts or screws should be capable of being loosened afterwards unless they are specifically designed for permanent attachment
