Water-free cleaning device for photovoltaic module

Abstract

A water-free cleaning device for a photovoltaic module is composed of a cleaning cover (27) and a foldable stopping frame (35). The cleaning cover (27) cleans the photovoltaic module, and the foldable stopping frame (35) provides a stopping position for the cleaning cover (27). When the water-free cleaning device does not work, the cleaning cover (27) is located above the foldable stopping frame (35), and when the water-free cleaning device works, the cleaning cover (27) is separated from the foldable stopping frame (35) and moves to the photovoltaic module (30) to clean the photovoltaic module (30). According to the water-free cleaning device, the basic functions of scraping, whisking and sucking for cleaning the photovoltaic module are integrated, power is provided for the automatic water-free cleaning device for the photovoltaic module through unavailable energy of the photovoltaic module, and automatic running and cleaning of the cleaning cover on the surface of the photovoltaic module is achieved in the mode that the upper edge frame of the photovoltaic module serves as a rail.

Description

technical field [0001] The invention relates to a photovoltaic module cleaning device of a solar photovoltaic module power generation system. Background technique [0002] The amount of photovoltaic power generation mainly depends on the number of photovoltaic modules, efficiency of photovoltaic modules, transmission loss of inverter efficiency, solar radiation, environmental impact and operation and maintenance management. The surface pollution of photovoltaic modules is the main reason for affecting the power generation. The surface pollution of photovoltaic modules will block the light reaching the photovoltaic modules and affect the heat dissipation. In addition, the dust with acid and alkali deposits on the surface of photovoltaic modules, which will corrode the board surface after a long time, making it Rough and uneven. The rough and uneven surface of the component is more conducive to further accumulation of dust, and at the same time increases the diffuse reflectio...

Problems solved by technology

However, they all have the following common features: 1. The cleaning method is physical + chemical + water cleaning, and the surface of the component is easily damaged; 2. Secondary energy consumption; 3. Cannot be cleaned in time every day; 4. High operating costs

[0007] Combined with China's national conditions, there are very big differences in the application of different power plants. For example, in the photovoltaic power plants in Northwest China, the area is dry and water-scarce. According to statistics, the water consumption (single time) for cleaning photovoltaic cells is ≥50 tons / 10MW. It is a dilemma, and the cleaning cycle is based on the accumulation of contamination on the surface of the components, and it cannot be cleaned in time, so it also faces the loss of power generation
