Solar photovoltaic panel grey water absorption and removal device

Abstract

The invention discloses a solar photovoltaic panel grey water absorption and removal device, and belongs to the technical field of solar photovoltaic power generation. The device comprises an upper water absorption plate and a middle water diversion plate, and the shapes of the upper water absorption plate and the middle water diversion plate are matched with the outer surface of the lower frame of the photovoltaic panel; the front end of the upper water absorption plate is bent to form a water absorption end; a plurality of hollow strip-shaped grooves are formed in the upper water absorptionplate and the middle water diversion plate; the trend of the hollowed-out strip-shaped grooves is consistent with the bending trend of the upper water absorption plate and the middle water diversion plate, an opening in the front end of the water absorption end of each hollowed-out strip-shaped groove serves as a starting point, and the end point of each hollowed-out strip-shaped groove is closedin the middle water diversion plate and does not exceed the portion between the lower end of the middle water diversion plate and the hollowed-out strip-shaped grooves to form water diversion teeth. After installation, grey water accumulated on the surface of the solar photovoltaic panel can be conveniently and effectively absorbed and removed.

Description

technical field [0001] The invention relates to a device for removing gray water on the surface of a photovoltaic panel, which belongs to the technical field of solar photovoltaic power generation. Background technique [0002] At present, in solar photovoltaic power generation projects, the surface of photovoltaic panels is left unattended for a long time, causing a layer of dust to accumulate on the surface, which has an impact on the efficiency of photovoltaic power generation. At the same time, the general installation of photovoltaic panels will have a certain angle. Under the action of rain, dew or artificial water spraying, it is easy to form a certain area of ​​water on the lower frame of the photovoltaic panel, and the accumulated water may penetrate into the photovoltaic panel. Cause damage, stagnant water mixes with dust to form gray water, and also causes a certain loss of solar power generation efficiency. Moreover, solar cell modules shaded by gray water will ...

Problems solved by technology

[0002] At present, in the solar photovoltaic power generation project, the surface of the photovoltaic panel is left unattended for a long time, causing a layer of dust to accumulate on the surface, which has an impact on the efficiency of photovoltaic power generation

At the same time, the general installation of photovoltaic panels will have a certain angle. Under the action of rain, dew or artificial water spraying, it is easy to form a certain area of ​​water on the lower frame of the photovoltaic panel, and the accumulated water may penetrate into the photovoltaic panel. Cause damage, accumulated water mixed with dust to form gray water, will also cause loss of certain solar power generation efficiency

Moreover, solar cell modules shaded by gray water will generate heat and produce a hot spot effect, which can seriously damage solar cells

[0003] The existing cleaning methods include manual cleaning and erasing, automatic spraying device, automatic ash wiping device, etc., but the cost is high or inconvenient. It is necessary to design a simple and effective ash removal device for the surface of photovoltaic panels
