Description

Technical Field

[0001] The utility model relates to solar energy technology, in particular to a sludge discharging and water guiding component for a photovoltaic panel. Background Art

[0002] Solar photovoltaic modules can convert the light energy in sunlight into electrical energy; solar power generation has become one of the most important components of clean energy and renewable energy.

[0003] When the modules are installed, since there is a certain inclination angle between the modules and the ground direction, taking a photovoltaic power station with an installation inclination angle of 15° in the southern region as an example, although the rainfall is sufficient and the photovoltaic modules can be effectively washed by rainwater, due to the limitation of the frame structure for fixing the photovoltaic modules, after rainfall, there will inevitably be some accumulated water remaining on the side edges of the photovoltaic modules. When the accumulated water evaporates, a small amount of dust will accumulate on the glass panel of the photovoltaic modules, and over time, a sludge belt will be formed.

[0004] If this sludge belt cannot be effectively cleaned, it will affect the drainage of rainwater, and the rainwater will carry a large amount of impurities in the air, forming solutions with different acids and alkalis, which are corrosive. When the rainwater stays between the frame and the glass for a long time, it will corrode the photovoltaic silica gel of the sealing component, not only affecting the overall strength of the photovoltaic module, but also corroding the photovoltaic panel after corroding the silica gel, resulting in premature yellowing and attenuation of the photovoltaic module and greatly reducing the service life.
