ASTM E1830-15

4.1 The useful life of photovoltaic modules may depend on their ability to withstand periodic exposure to high wind forces, cyclic loads induced by specific site conditions or shipment methods, high loads caused by accumulated snow and ice on the module surface, and twisting deflections caused by mounting to non-planar surfaces or structures. The effects on the module may be physical or electrical, or both. Most importantly, the effects may compromise the safety of the module, particularly in high voltage applications, or where the public may be exposed to broken glass or other debris.

4.2 These test methods describe procedures for mounting the test specimen, conducting the prescribed mechanical tests, and reporting the effects of the testing.

4.3 Data obtained during testing may be used to evaluate and compare the effects of the simulated environments on the test specimens. These test methods require analysis of both visible effects and electrical performance effects.

4.4 If these test methods are being performed as part of a combined sequence with other mechanical or nonmechanical tests, the results of the final electrical test (7.2) and visual inspection (7.3) from one test may be used as the initial electrical test and visual inspection for the next test; duplication of these tests is unnecessary unless so specified.

4.5 Some module designs may not use any external metallic components and thus lack a ground point designation by the module manufacturer. In these cases, the ground path continuity test is not applicable.

1.1 These test methods cover procedures for determining the ability of photovoltaic modules to withstand the mechanical loads, stresses and deflections used to simulate, on an accelerated basis, high wind conditions, heavy snow and ice accumulation, and non-planar installation effects.

1.2 These test methods define photovoltaic test specimens and mounting methods, and specify parameters that must be recorded and reported.

1.3 Any individual mechanical test may be performed singly, or may be combined into a test sequence with other mechanical or nonmechanical tests, or both. Certain preconditioning test methods such as annealing or light soaking may also be necessary or desirable as a part of such a sequence. However, the determination of such test sequencing and preconditioning is beyond the scope of these test methods.

1.4 These test methods do not establish pass or fail levels. The determination of acceptable or unacceptable results is beyond the scope of these test methods.

1.5 These test methods do not apply to concentrator modules.

1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7 The following precautionary caveat pertains only to the hazards portion, Section 6, and the warning statements, 7.5.3.2 and 7.6.3.2, of these test methods.
