Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a data acquisition device for a solar power generation system. Background technique [0002] Solar power generation is divided into photothermal power generation and photovoltaic power generation. Generally speaking, solar power generation refers to solar photovoltaic power generation, referred to as "photoelectricity". Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is a photovoltaic cell. Photovoltaic cells are packaged and protected after being connected in series to form a large-area photovoltaic cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation system. [0003] Photovoltaic cell modules are mostly installed in outdoor environments, and the ...
