Description

technical field [0001] The invention relates to a junction box for photovoltaic modules, in particular to a junction box for intelligent solar photovoltaics based on the Internet of Things. Background technique [0002] Solar photovoltaic cells (PVCell) are used to directly convert the sun's light energy into electrical energy. Ground photovoltaic systems use silicon solar cells based on silicon in large quantities. Silicon solar cells are divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon solar cells. , In terms of comprehensive performance such as energy conversion efficiency and service life, monocrystalline silicon cells and polycrystalline silicon cells are superior to amorphous silicon cells, while polycrystalline silicon cells have lower conversion efficiency than monocrystalline silicon cells, but are cheaper. [0003] According to application requirements, solar cells are assembled into a group of photovoltaic cells that can output ...

Problems solved by technology

[0004] However, photovoltaic modules are used outdoors for a long time, and most of the large-scale power station systems are used in remote mountainous areas, plateaus and other places with sufficient heat. The top of the solar panel is easily covered by foreign matter, causing the current and voltage emitted by the photovoltaic module panel to be unstable. If the area is large, it will cause instability and combustion to the entire power grid. The battery in the solar panel is very sensitive to temperature. As long as the temperature rises, the efficiency of the battery will decrease.
