光伏（PV）组件降解率分析量化了PV功率输出随时间的损失，有助于估计降解对能源成本的影响。了解所有电流-电压（I-V）参数的退化有助于确定退化的原因，并为系统的设计提供有用的信息。这项研究报告了在科罗拉多州戈尔登的国家可再生能源实验室（NREL）部署的12个不同的单晶和多晶模块收集的数据。大多数被调查的模块显示，由于短路电流下降，最大功率下降< 0.5%/年。
Photovoltaic (PV) module degradation rate analysis quantifies the loss of PV power output over time and is useful for estimating the impact of degradation on the cost of energy. An understanding of the degradation of all current-voltage (I-V) parameters helps to determine the cause of the degradation and also gives useful information for the design of the system. This study reports on data collected from 12 distinct mono- and poly-crystalline modules deployed at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. Most modules investigated showed < 0.5%/year decrease in maximum power due to short-circuit current decline.
