The Internet-of-things solar photovoltaic assembly controller comprises junction boxes which are in series connection; solar panel connection lines and diodes are arranged in the junction boxes; the output ends of the junction boxes are connected with cables; temperature control system modules, power supply control system modules, ZigBee modules and communication system modules are arranged in the junction boxes; the Internet-of-things solar photovoltaic assembly controller further comprises a gateway wireless communication module and a management center server; and the management center server establishes a network connection with a computer terminal or mobile terminal and performs data processing on acquired temperature information and power supply information. With the controller provided by the invention adopted, stable and real-time data transmission of a large-scale photovoltaic power station system can be realized; data acquisition and analysis of individual photovoltaic panels can be mastered online; and first-hand data can be provided for solar photovoltaic power generation; data basis can be provided for the improvement of the conversion efficiency of the photovoltaic panels; manpower can be save; problems can be handled once found; and major accidents can be avoided.

Description

technical field [0001] The invention discloses a solar photovoltaic module controller of the internet of things, and relates to the technical fields of solar photovoltaic and the internet of things. Background technique [0002] Solar photovoltaic cells (PVCell) (referred to as photovoltaic cells - SolarCell) are used to directly convert the sun's light energy into electrical energy. Silicon solar cells based on silicon are widely used in terrestrial photovoltaic systems, which can be 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 and polycrystalline silicon cells are superior to amorphous silicon cells. Polysilicon is less efficient than monocrystalline silicon, but it is cheaper. Such as: crystalline silicon solar cells, thin film solar cells, silicon heterojunction (HIT) solar cells, etc. According to th...

AI Technical Summary

Problems solved by technology

Exposure to wind and sun for a long time can easily cause foreign objects to cover the surface of the battery panel, resulting in unstable current and voltage. 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
