Solar panel

Technical Field

The application belongs to the technical field of energy conservation and environmental protection, and relates to a solar panel.

Background

Solar energy is a novel energy source with energy saving and environmental protection, and a solar panel (also called as a solar cell module) is a core part in a solar power generation system and is also the most important part in the solar power generation system. A lot of large-scale solar power stations invest a lot of funds during construction, but the service life is short, and a lot of waste is caused. The reason that the service life of the solar cell is short is analyzed, namely, the wind sand is large sometimes, and the solar panel is impacted by the airflow and objects mixed in the airflow; secondly because the fallen leaves on solar panel, bird's droppings and other article that are blown down by wind cause the small size to shelter from solar panel, cause the hot spot effect, shelter from the part promptly and form a resistance, do not shelter from the part and regard as power supply, after the time is of a specified duration, "resistance" generates heat, is accelerated ageing with higher speed by the part of sheltering from the battery, further generates heat, until burning out the battery, finally monoblock subassembly destroys.
