Research on PV Array Voltage Characteristic Test System Design

摘要

Solar photovoltaic power generation is an important part of the system, and the work efficiency and system capacity is closely related to improving the energy conversion efficiency of the solar cell can increase the utilization of solar energy. Because of the characteristics of solar cells have a number of factors affecting the practical application, therefore, when configuring the array of photovoltaic cells, the need to test its characteristics, select the cell array to meet the requirements, improve the efficiency of photovoltaic power generation system. By analyzing the volt-ampere characteristics and testing requirements for photovoltaic cell array, is designed to test the system, discusses the overall system architecture, and system testing principle was studied briefly analyzes the main part of the system functions.
