Abstract: This paper proposed a photovoltaic power plant energy efficiency evaluation system based on computer monitoring
system. System performance is disassembled according to links and equipment and performance is embodied in each component
and each section of the circuit in this system. At the same time, it also proposed typical node settings and performance calculation
model. The system is divided into data acquisition unit, data analysis unit and realization unit in terms of composition, and it
makes full use of redundant interfaces and redundant channels without changing the structure of the power station, which can
provide support for the efficiency evaluation and operation and maintenance of the power station.

Key words: energy efficiency evaluation; photovoltaic power station; real-time
