Photovoltaic module

Abstract

The invention provides a photovoltaic module. The photovoltaic module comprises a frame and a module body arranged in the frame. The photovoltaic module further comprises a moving device, a cleaning device arranged on the moving device and a controller. The moving device is arranged above the module body and drives the cleaning device through self movement to move above the surface of the module body. The cleaning device comprises a spray head and a brush. The spray head is used for spraying water to attached blocking articles on the surface of the module body and spraying gas to non-attachedblocking articles on the surface of the module body. The brush is used for brushing the surface of the module body after the spray head sprays water. The controller is connected with the moving deviceand the cleaning device and used for controlling the moving device to move and controlling the cleaning device to work. The photovoltaic module has the function of cleaning.

Description

Technical field [0001] The present invention relates to the field of photovoltaic technology, in particular to a photovoltaic module. Background technique [0002] With the large number of distributed rooftop photovoltaic power stations being built, how to clean the photovoltaic modules in the distributed rooftop photovoltaic power station has become a more serious problem. At present, the cleaning method of photovoltaic modules in distributed rooftop photovoltaic power stations is mainly manual, that is, operation and maintenance personnel climb on the roof and use cleaning tools to clean photovoltaic modules. The disadvantages of this cleaning method are: [0003] (1) Due to the limited frequency of manual cleaning, it cannot be guaranteed that the obstructions (such as bird droppings, leaves, paper, plastic bags, etc.) on the surface of the photovoltaic module can be found and cleaned in time. If the obstructions on the surface of the photovoltaic module cannot be cleaned in t...

AI Technical Summary

Problems solved by technology

The disadvantages of this cleaning method are:

[0003] (1) Due to the limited frequency of manual cleaning, it is impossible to ensure that the obstructions (such as bird droppings, leaves, paper, plastic bags, etc.) on the surface of photovoltaic modules can be found and cleaned in time

If the shelter on the surface of the photovoltaic module cannot be cleaned in time, hot spots will be generated, which will affect the normal power generation of the photovoltaic module

In severe cases, it will also cause damage to photovoltaic modules.

[0004] (2) The manual cleaning method will not only greatly increase the operation and maintenance cost of the distributed rooftop photovoltaic power station after completion, but also greatly increase the operation and maintenance risk because the personal safety of the operation and maintenance personnel cannot be fully guaranteed
