[0003] With the continuous growth of the solar photovoltaic power generation industry, engineers and technicians have higher and higher requirements for solar cell module testing and measurement solutions, especially in the field of photovoltaic system application research and testing. Currently, there is no mature and user-friendly solution overall test system

In addition, at present, the power generation efficiency analysis of photovoltaic power plants depends on the environmental data recorded by the environmental detector, while the radiation recording instruments in the conventional environmental detection are all pyranometers in the form of thermocouples. The radiation data recorded by the instrument is consistent with the solar cell The spectral range is inconsistent, and the installation angle, temperature characteristics, and surface dust are all different from the solar cell components in the operation of the photovoltaic power station, which will cause certain errors in the analysis of the power generation efficiency of the photovoltaic power station.
