本标准中试验程序的目的是在尽可能合理的经费和时间内确定组件的电性能和热性能，表明组件能够在规定的气候条件下长期使用。本标准不适用带聚光器的组件。

Scope

This standard specifies the requirements for the design, appraisal and finalization of ground-use thin-film photovoltaic modules, which are used for a long time under the general outdoor climate conditions defined in GB/T 4797.1-1984 and IEC 60721-2-1 Amendment 1: l987 . This standard was formulated based on amorphous silicon thin-film module technology, but it is also applicable to other thin-film photovoltaic modules. In view of the special characteristics of other new technologies, it may be necessary to modify the test procedure. This test procedure is mainly formulated in accordance with GB/T 9535-1998 ((Design Appraisal and Finalization of Crystalline Silicon Photovoltaic Modules for Ground Use), and some necessary modifications have been made for the special properties of amorphous silicon thin film modules. Light aging is used to distinguish light Attenuation and other attenuation mechanisms, and the maximum power at the end of the test program is used as an estimate of the long-term working performance of the thin film module. In order to distinguish the annealing effect that may occur in the thermal cycle and wet-heat tests, the components need to be annealed before these tests. For different For other thin film formation techniques using amorphous silicon, pretreatments such as photoaging and annealing may be different or may prove unnecessary. Because all types of thin film components are susceptible to corrosion caused by moisture, a wet leakage current test shall be added to this test. The purpose of the procedure is to determine the electrical and thermal properties of the components within as reasonable a cost and time as possible, showing that the components are capable of long-term service under the specified climatic conditions. The actual life expectancy of a component passing this test will depend on the design of the component and the environment and conditions they are used in. This standard does not apply to components with concentrators.
