Description
Technical Field
The invention relates to the field of photovoltaic power generation maintenance, in particular to a project for improving the power generation efficiency of a photovoltaic panel, improving the external environment of the photovoltaic panel and prolonging the service life of the photovoltaic panel.
Background
The solar photovoltaic cell mainly functions to convert light energy into electric energy, and this phenomenon is called photovoltaic effect. However, this causes a lot of inconvenience when selecting raw materials of solar panels. We are asked to consider the photoconductive effect of the material and how to generate the internal electric field. Not only the light absorbing effect but also the light guiding effect thereof needs to be looked at. The choice of materials is a great constraint for photovoltaic power generation. Even if photoelectric conversion is performed with a very efficient material, its efficiency is still low.
The accumulation of surface dust causes the reduction of the illuminated area of the surface of the photovoltaic panel, and also aggravates the aging of the photovoltaic panel; the heat production in the power generation process also reduces the energy conversion efficiency simultaneously, so that the photovoltaic power generation encounters great trouble and produces more adverse effects.
Disclosure of Invention
In order to overcome the defects that the energy conversion rate is reduced due to insufficient heat dissipation of a photovoltaic panel, the illumination area is reduced due to accumulation of surface dust and the like in the prior art, the surface dust of the solar photovoltaic panel is washed away by mainly utilizing recovery of natural rainfall, and a water cooling pipeline is arranged to cool the photovoltaic panel, so that the energy conversion efficiency of the photovoltaic panel is improved, and the service life of the photovoltaic panel is prolonged.

When the washing times reach the specified limit, the atomization device stops working; the water pump finally stops pumping water under the action of the counter, and the spiral cooling pipeline stops circulating.
Foretell a photovoltaic power generation cooling system and device can realize the recycle of water, has improved photovoltaic power generation's efficiency when green. The pressure water mist spray head on the upper portion utilizes proper pressure to wash away sand dust and sundries in gaps inside the photovoltaic panel, the radiation area of the sun is maximized, and the absorption effect and the energy conversion rate of sunlight are increased.
The spiral cooling pipeline is adopted for cooling the photovoltaic panel, so that the contact area of the cooling pipeline and the photovoltaic panel can be increased, the photovoltaic panel can be cooled in a better power generation mode, and the conversion efficiency between solar energy and electric energy is guaranteed.
The invention has the advantages that as the rainwater recovery system and the urban water supply position supplementing pipeline system are integrated, the water level in the water collecting tank is always stable and is kept below a set standard position, and the normal operation of the photovoltaic panel cooling system is ensured; meanwhile, the atomization device is controlled by the photosensitive switch to be started and is controlled by the counter to stop, so that the whole system is more automatic and green.
