- The main contents include scope, terms and definitions, equipment, sampling, procedures, calculations, and test reports. During the power stabilization process of silicon-based thin film photovoltaic modules under the influence of light, the maximum power value is tested before and after each roughly equal irradiation cycle. The minimum irradiation cycle is 43kwh/m2, and the module reaches the standard in accordance with IEC 61215-2 MQT 19 After stabilization (IEC 61215-1-3: 2016 stipulates (PMAX-PMIN)/PAVE≤2%), the power still shows a continuous downward trend under continuous illumination. This standard gives the following equation as a criterion for determining whether the component's light-induced attenuation has reached final stability: Here, Pmax, Pmin, and Paverage are the maximum, minimum, and average values of the maximum power under three STCs measured in two consecutive cycles. value.
