光伏（PV）系统设计人员使用PV模块的性能数据来改进系统设计并使系统更具成本效益。由于与数据采集系统相关的高成本，这种有价值的数据的收集往往没有完成。在本文中，我们报告了一个低成本的电流-电压（I-V）测量系统的设计，用于监测光伏组件的I-V特性。从2001年10月和2002年11月之间监测7个晶体硅模块获得的结果，并进行了讨论。所获得的结果还显示了能够连续监测PV模块的电流-电压特性的价值。
Photovoltaic (PV) system designers use performance data of PV modules to improve system design and make systems more cost effective. The collection of this valuable data is often not done due to the high costs associated with data acquisition systems. In this paper, we report on the design of a low-cost current–voltage (I–V) measuring system used to monitor the I–V characteristics of PV modules. Results obtained from monitoring seven crystalline silicon modules between October 2001 and November 2002 are presented and discussed. Results obtained also show the value of being able to continuously monitor the current–voltage characteristics of PV modules.
