Photovoltaic array cross-panel cleaning method and device

Abstract

The invention discloses a photovoltaic array cross-panel cleaning method. The photovoltaic array cross-panel cleaning method comprises steps that a carrier is controlled by a control system for connecting with a present on-panel cleaner to drive the on-panel cleaner to leave the present position; a mover is controlled by the control system for driving the connected carrier to move to a region of a target photovoltaic panel; the relative position of the carrier and the target photovoltaic panel is adjusted by the control system, and the carrier is controlled for disposing the on-panel cleaner onto the target photovoltaic panel; the carrier is controlled by the control system for disconnecting with the on-panel cleaner, the on-panel cleaner is controlled by the control system for start and realize moving cleaning on the target photovoltaic panel, the mover is controlled by the control system for moving towards any on-panel cleaner accomplishing cleaning the corresponding target photovoltaic panel, or the mover is controlled for moving towards the initial position. The method is advantaged in that movement and conversion of the on-panel cleaner can be realized among different photovoltaic panels, utilization efficiency of the mover is improved, and photovoltaic panel cleaning complexity of artificial driving cleaning equipment can be reduced.

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.
