This paper analyses the performance of a rooftop photovoltaic (PV) plant installed on the city rooftops in south China and a desert PV plant in remote desert in northwest China. A subsystem of the rooftop PV plant and a subsystem of the desert PV plant were monitored by a data acquisition system. The results showed that the performance radio (PR) of the rooftop PV subsystem and the desert PV subsystem...
This paper describes the development of a multifunctional data acquisition system for photovoltaic (PV) plants. The proposed system consists of a set of data collection boxes for measuring electrical parameters (e.g. DC current, DC voltage, AC current, AC voltage, AC power, etc.), a meteorological data collection system for measuring meteorological parameters (e.g. irradiance, ambient air temperature,...
This paper describes a performance monitoring and test system for grid-connected photovoltaic systems. The purpose of the research is to develop an on-site test platform to collect the data and evaluate the performance of the grid-connected PV system. The performance monitoring and test system consists of a meteorological data collection system for measuring meteorological parameters (e.g. irradiance,...
