Which method is faster and better for photovoltaic power station cleaning?

After analysis and calculation, the investment payback period of automatic cleaning equipment is about 2 years, and a return of more than 20% can be obtained during the life cycle.

According to the degree of intelligence, the cleaning process is divided into mechanical cleaning and manual cleaning.

1. Manual cleaning technology.

Currently, most of my country's photovoltaic power plants use manual cleaning.

When cleaning, usually a group of 2 to 3 people, one of them is responsible for water supply equipment and installation of pipes, the other uses a high-pressure water gun to rinse the components, and the other uses a mop to clean up the ash and dead corners, and then dry them.

With the development of science and technology, there has been an integrated manual cleaning tool integrating high-pressure water head and rotating brush. The push rod is made of carbon fiber material, which has the advantages of high efficiency, low water consumption, low labor intensity, and low price. Favored by photovoltaic power station cleaning companies.

For large ground-based power stations, manual cleaning is required every quarter, which takes about 1 to 2 months. The work efficiency is low and the cleaning cycle is long. There are often cases where the power station is not completely cleaned and is polluted again. For the power station, each cleaning takes about 1 to 2 months.

The disadvantage of manual cleaning is that the degree of cleanliness of the parts is heavily dependent on the responsibility of the construction personnel and cannot be effectively controlled.

2. Mechanical cleaning technology.

At present, mechanical cleaning technology can be divided into three solutions: 1) single-row cleaning, 2) multi-row cleaning, and 3) large-format cleaning.

1. Single-row cleaning technology.

Single-row cleaning technology means that the equipment can only clean one row of parts and cannot be discharged. This technology has been widely used in various photovoltaic power plants, and it is currently a technology with more models on the market.

2. Multi-row cleaning technology.

Various cleaning technologies can also be divided into three categories,

(1) The cleaning device in the car can send the equipment to the next row after a row of parts is removed. This process mostly uses water washing. The construction vehicle is equipped with a cleaning device, and the vehicle has its own water tank and water pump.

(2) "Ferry type" straddle-row cleaning technology. This technology is not yet mature, but many domestic manufacturers are conducting in-depth research. At present, the system has been applied to distributed power stations, and the ground power station project is still in the prototype test stage. The main reason is that the roof of the distributed power station is relatively flat and suitable for laying tracks. The environment and terrain of the ground power station are complex and changeable, so large areas cannot be made. Of laying.

(3) The cleaning robot body can realize autonomous steering and completely get rid of the dependence on the shuttle bus.

3. Large-scale clean technology.

Some large-scale distributed power station projects are very densely arranged, and there are not enough maintenance channels reserved, so the array width is usually very wide (usually more than 10 meters). Single-row or multi-row cleaning equipment due to the small gap between the components, the restricting wheel does not have enough installation space to use.

On this basis, the robot realizes the steering of the robot through the difference in the rotational speed of the walking wheel, and its cleaning method is similar to other cleaning techniques.
