Description

technical field [0001] The present invention relates to the technical field of new energy exploration, in particular to the exploration technology of large-scale solar power generation, and specifically to a system for measuring the efficiency of solar photovoltaic power generation. Background technique [0002] Solar energy resources have the characteristics of intermittent, periodic, and volatility, and there are many factors that affect solar power generation. Due to the wide distribution and remote location of the solar photovoltaic power generation system, it brings great challenges to the communication between the equipment and the site. The management personnel cannot timely understand the operation status and efficiency of the power generation system, which is not conducive to the determination of the total power generation of the solar photovoltaic power generation system. . [0003] The efficiency of solar photovoltaic power generation system is the ultimate indic...
