Description

Technical Field

[0001] The utility model relates to the technical field of temperature monitoring devices, in particular to a temperature monitoring device for a solar cell panel. Background Art

[0002] During the operation of solar panels, the surface temperature will change. The temperature directly affects the power generation efficiency and service life of the solar panels. When the temperature of the panels rises, the power generation efficiency will decrease because high temperature will slow down the migration speed of charge carriers inside the battery, thereby reducing the generation of electrical energy. Therefore, temperature monitoring devices will be installed to monitor the temperature of the panels in real time and take timely measures to prevent the temperature from being too high.

[0003] At present, some temperature monitoring devices for solar panels on the market directly measure the temperature through temperature-sensitive optical fibers laid on the back of the solar panels, and upload the data in real time to a joint management platform for monitoring and analysis. However, this method can only monitor the temperature at a certain position on the back of the panel. In some cases, solar panels may produce a hot spot effect. The hot spot effect refers to the situation in which, due to local shadow obstruction, dust deposition, bird droppings pollution, etc., the obscured cells in the photovoltaic module cannot work normally, but instead become a load, consuming the electricity generated by other cells. The hot spot effect will cause these cells to heat up. At this time, it is necessary to monitor different positions of the solar panel to determine the location where the hot spot effect occurs, so as to clean the surface of the solar panel or adjust the working state. To this end, a temperature monitoring device for solar panels is proposed. Utility Model Content
