Cleaning method for photovoltaic panels in solar photovoltaic arrays

Abstract

The invention relates to a cleaning method for photovoltaic panels in solar photovoltaic arrays. For solar photovoltaic arrays which are distributed in sloping lands and mountain lands and are short in length, a plurality of distributed fixed water supply stations are arranged to cover an operation area radiated by the whole photovoltaic power station, and the operation area radiated by the wholephotovoltaic power station radiation is provided with a movable first plunger pump, a movable first wire take-up device and one or more cleaning robots. After one fixed water supply station completesthe cleaning operation through the cleaning robots, the first plunger pump, the first take-up device and the cleaning robots are moved to the next fixed water supply station through manpower to continue the cleaning operation. For photovoltaic arrays which are distributed in plains and deserts and are long in length, a supply station is mounted on a motor vehicle, the motor vehicle is equipped with a cleaning robot simultaneously, and the cleaning robot automatically conducts the cleaning operation in the motor vehicle moving process till the cleaning operation is completed. The cleaning method has the characteristics of low cost, convenient operation and high cleaning efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of cleaning robots, and in particular to a method for cleaning photovoltaic panels in a solar photovoltaic array. Background technique [0002] As a renewable and clean energy, solar photovoltaic has become an important force in today's global energy revolution. The surface of solar panels is easy to accumulate dirt such as sand, dust, etc. If it is not cleaned scientifically and professionally in a timely manner, the maximum power generation power of the modules will be reduced by 40% to 60%, and the power generation will be reduced by 20% to 30%. Therefore, the concept of improving power generation and efficiency of power stations through reasonable and scientific cleaning of solar panels and careful maintenance of components has been recognized by the industry. [0003] At present, there are many products in the market that rely on adding specific sensing devices or fixing devices t...

Problems solved by technology

However, for most of the photovoltaic power plants that are heavily covered by dust or in long-term wind and sand environments, some dirt has stuck to the photovoltaic panels, and only relying on the rotation of the brush roller or working together with the sprinkler is not enough to completely clean the photovoltaic panels, resulting in some photovoltaic panels. Dirt still exists in the existing area, affecting power generation efficiency and causing certain equipment damage
