Photovoltaic array cross board cleaning method and device

Abstract

The invention discloses a photovoltaic array cross board cleaning method. The method comprises the steps that a control system controls a carrier to adjust the attitude to be connect with an on-board cleaning machine and controls the carrier to drive the on-board cleaning machine to leave a photovoltaic board; the control system controls a mover to drive the carrier to move, and controls the mover to carry out corresponding operation when the mover moves to the area of a target photovoltaic board; the control system adjusts the relative position of the carrier to the target photovoltaic board, and controls the carrier to place the on-board cleaning machine on the target photovoltaic board; and the control system controls the on-board cleaning machine to carry out mobile cleaning on the target photovoltaic board. According to the invention, the cleaning operation of the photovoltaic board and the movement and conversion of the on-board cleaning machine between different photovoltaic boards are realized; the complexity for a man-driven cleaning vehicle to clean the photovoltaic board can be reduced; the application range of on-board cleaning devices is expanded; the cleaning efficiency is improved; the service life of the photovoltaic board is prolonged; and the power generation efficiency and utilization of the photovoltaic board are enhanced.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic panels, and more specifically, to a photovoltaic array cross-panel cleaning method and device. Background technique [0002] With the improvement of environmental protection requirements and sustainable energy demand, the proportion of clean energy in the total energy has been increasing year by year, and the demand for cleaning photovoltaic panel arrays is gradually heating up in the current market. [0003] There are two main reasons why photovoltaic arrays need to be cleaned: 1. Dirt will cause differences in heat conduction on the surface of photovoltaic panels, which will eventually cause "hot spots" and damage photovoltaic modules; 2. Dirt will reduce the transmittance of the surface of photovoltaic panels, thereby affecting photovoltaic panel components. The light-to-heat conversion rate of the array, that is, reduces the power generation efficiency. Therefore, in order to ensur...

Problems solved by technology

However, there are problems in the above methods: in the first method, the high-pressure water washing solution is extremely water-consuming; in the second solution, the dry brushing solution on the photovoltaic panel needs to invest a lot of equipment per unit cleaning area, and the cleaning effect is not ideal ; In the third solution, the reliability of the ground-moving chassis robotic arm roller brush cleaning vehicle is low, the operation is difficult, and it is easy to damage the photovoltaic panels, which is easy to cause waste of resources and damage to the cleaning objects.
