Scope

GB/T 43057-2023 is the English-translated version of 光伏组件动态机械载荷试验.

GB/T 43057-2023 is the Chinese standard "Photovoltaic(PV) modules - Dynamic mechanical load testing". Its scope clause reads: This document specifies methods for dynamic mechanical load testing of photovoltaic modules.

The photovoltaic modules are placed on the designed support points and applied vertically to The uniform load on the surface of the photovoltaic module cycles alternately in forward and reverse directions.

This test is used to evaluate components such as solar cells, interconnect strips and/or electrical connections Are the internal components susceptible to breakage or are the edge seals subject to loss due to mechanical stress during installation and operation of the PV module? effect.

This test is performed at any temperature within the normal operating temperature range of the component. Since the component temperature during load application affects the test results Therefore, it is crucial to keep the component temperature constant during the test.

This document is applicable to the testing of rigid components and is not applicable to flexible components, but can be used for flexible components with rigid supports.

This document is an independent technical specification, but is often used in conjunction with other standards. Normally no functional effects will occur when this test is performed alone.

However, after this test is performed, other tests such as thermal cycle tests and moisture-freezing tests will cause power losses. This power loss Failure results from damage to components caused by dynamic mechanical loads, not just thermal cycle testing and moisture-freezing cycle testing.

For example, transportation testing The procedure (IEC 62759) requires 50 thermal cycle tests and 10 moisture-freeze cycle tests after the dynamic mechanical load test.

Its clauses include normative reference documents; terms and definitions; test device.
