Example Embodiment

[0025] The present invention proposes to take a water source from air as a photovoltaic plate as a photovoltaic plate, and the semiconductor refrigeration is introduced, allowing air flowing through the semiconductor to cool the semiconductor, so that air cools, and partially water vapor in the air is condensed on the refrigeration end surface of the semiconductor. And formed a water droplet. Under the action of gravity, the water beads finally flow into the water storage tank.

[0026] In order to maintain the flow of air, the invention proposes to provide power to the chimney effect formed by solar heating, so that the flow of air is arranged to flow from the bottom. The cold air is entered from the bottom of the passage by symmetrically installing two air on both sides of the photovoltaic plate, and flows from the bottom of the passage and flows from bottom to the passage. At the top of the photovoltaic plate, it is considered to install an air discharge passage, and the air is...

Abstract

The invention discloses a solar photovoltaic panel self-cleaning device and method for taking water from the air. The air temperature is reduced through semiconductor refrigeration, part of water vapor in the air is condensed on the refrigeration end face of a semiconductor to form water drops, and the water drops are collected in a water storage tank to serve as a photovoltaic panel self-cleaning water source. In order to maintain air flow, an air exhaust channel is installed on the top of the photovoltaic panel, and the outer surface of the air exhaust channel is coated with a black heat absorption coating. Under heating of the solar energy, the air exhaust channel is heated and forms a temperature difference with the air in an inlet channel, a chimney effect is formed, and the air is driven to be automatically exhausted from the top end of the exhaust channel. A wiping mode is adopted for self-cleaning, a rubber cleaning brush is driven by a motor, an electric valve is introduced to control the water outlet time of the water storage tank, the surface of the photovoltaic panel is deeply cleaned in cooperation with the cleaning brush, the water taking problem of self-cleaning of the photovoltaic panel is solved, and the device has the advantages of being wide in application range, capable of saving energy, high in automation degree and the like.

Description

technical field [0001] The invention belongs to the field of solar photovoltaics, and in particular relates to a solar photovoltaic panel self-cleaning device and method for taking water from the air. Background technique [0002] Solar energy is one of the most important renewable energy sources. How to efficiently convert solar energy into electrical energy has always been the focus of attention all over the world. Photovoltaic power generation is one of the common solar power generation methods, which has the characteristics of relatively high conversion efficiency, safety, and flexibility. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface (that is, the phenomenon that a semiconductor generates an electromotive force when it is irradiated by light). The key component of this technology is a solar cell. Solar cells are packaged and protected after being c...
