Mechanical fatigue life analysis of solar panels under cyclic load

From manufacturing to field operation, photovoltaic modules are subject to dynamic loads. Cyclic load produces dynamic bending moments with tensile and compressive stresses within the solar cells and interconnects. This often leads to fatigue of solar cell interconnects, cell crack initiation, and worsening of pre-existing cracks because of the

6 FAQs about [Photovoltaic support load test procedures]

Can a PV system be tested if a load changes?

These tests do not cover PV systems connected to an electric utility. Test results are only relevant to the system tested. If the PV system or load changes in any way, then the tests should be rerun on the modified system. It may be desired to run performance tests on the load (s).

Can a stand-alone photovoltaic system be tested?

Abstract: Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load. The methodology includes testing the system outdoors in prevailing conditions and indoors under simulated conditions.

What is a stand-alone PV system performance test?

Such tests, however, are beyond the scope of this recommended practice and may require specialized test equipment and procedures. Purpose: An evaluation of stand-alone PV system performance is needed to determine how well the PV array charges the battery and how well the battery is sized for the load.

Can a PV system be tested on a modified system?

Test results are only relevant to the system tested. If the PV system or load changes in any way, then the tests should be rerun on the modified system. It may be desired to run performance tests on the load (s). Such tests may be found in other documents, for example, Servant and Aigullon [B7] describe how to test a lamp in a photovoltaic system.

What is a good test voltage for a PV module?

For example, consider a single-ended test of a PV string with Voc of 475V and a PV module maximum system voltage spec of 1000V. Setting the meg tester’s test voltage to 500V will keep all points in the circuit below 1000V.

What tests are required for a PV system?

PV system. These tests on completion generally consist of avisual inspection to identify defects, unfinished work and non-compliance with contractual and planning requirements; functional tests of all key components required for the system to generate and supply electricity to the grid; a
