IEC TR 63279:2020回顾了顺序和组合加速应力试验的研究，这些试验旨在确定光伏组件在单因素和稳态试验未显示的现场出现退化模式的可能性。本文件旨在提供基于数据和理论的动机，并帮助可视化改进加速应力测试的下一步，该测试将对光伏组件材料和设计产生影响。可靠性的提高和风险的降低带来的任何增量节约都会转化为光伏发电的较低平准化成本。 较低的成本将导致更快地采用光伏以及可再生能源的相关效益。

IEC TR 63279:2020 reviews research into sequential and combined accelerated stress tests that have been devised to determine the potential for degradation modes in PV modules that occur in the field that single-factor and steady-state tests do not show. This document is intended to provide data and theory-based motivation and help visualize the next steps for improved accelerated stress tests that will derisk PV module materials and designs. Any incremental savings as a result of increased reliability and reduced risk translates into lower levelized cost of electricity for PV. Lower costs will result in faster adoption of PV and the associated benefits of renewable energy.
