Air Compressor Application in Photovoltaic power generation Industry

Silicon ingot

The main applications for compressors are: blowing off dust from cell walls, spraying and protection air. The air consumption at the 1GW plant is about 60m3/min。

Silicon wafer

The photovoltaic industry relies heavily on pneumatic control for its operations. This includes using compressed air to power machines, such as sweepers, as well as employing pneumatic valves to control various processes.

Cells

Air compressors are used in the cleaning and maintenance of solar cells. They are also used for various processes such as blowing, pneumatic valve drives, and protection air systems. The cleaning, coating, diffusion, PECVD, and silicon wafer etching processes heavily rely on compressed air. Additionally, compressed air is necessary for blasting, guarding, and measurement in the industry.

Solar modules

Air compressors play a crucial role in various applications. They are used to power the valves, cylinders, and arms of robots, as well as to cool welding tools and operate spraying stations and cleaning machines. Additionally, air compressors are essential for wet-jet and dry-jet cleaning processes that require a high volume of air.

How to Choose Air Compressor for Photovoltaic power generation Industy

In the photovoltaic industry, there are more than 90% of equipment required compressed air, especially for battery sheet manufacturing processes, as well as energy efficiency and heat recovery ability is a customer’s major concerns. In addition, solar product precision requirements are high and demand extremely high quality of air from the air compressor outlet out of pollution and impurities.
Based on the above-mentioned, photovoltaic industry is more suitable for oil-free screw air compressor and centrifugal air compressor without oil.

Oil-free Water Lubricated Air Compressor：

The Photovoltaic power generation industry requires high-quality gas output, and this is where water-lubricated compressors come in. These compressors are designed to meet the specific needs of special industries, and they have quickly gained popularity in the market. With features like high discharge volume, high pressure, and low noise, these compressors are efficient and reliable. They also have automatic water change and system cleaning functions, which help to keep the compressor clean and reduce maintenance costs. Additionally, the PLC intelligent control system allows for 24-hour remote control, ensuring continuous and stable operation for extended periods.

Centrifugal Air Compressor：

Centrifugal compressor is widely used in industrial, mechanical industry and other fields. The features of centrifugal compressors are high efficiency, low noise and small size. This type of air compressor is widely used in the medical field, food industry and DIY project. It can replace the piston-type compressor in many cases, which enjoys a good reputation in the market.

Dry Oil-free Rotary Screw Air Compressor

Water Lubricated Oil-free Air Compressor

This series of water lubricated compressors was specially designed to ensure that high standard gas output requirements in special industries can be met. After its launch, it attracted great market attention and was called “the air that you could breathe”. Features: large discharge volume, high discharge pressure (single stage pressure may reach 17 bars); high efficiency, low noise; close to the temperature compression machine with long service life; automatic water change and system cleaning functions can keep the inside of the compressor clean and tidy and reduce maintenance costs; PLC intelligent control system can realize 24-hour remote control. It guarantees continuous stable operation for a long time.

Centrifugal Air Compressor

Centrifugal compressors are often used in photovoltaic power generation industries for their ability to provide high-pressure flows of air and gas with relatively low efficiency. This is achieved by using a rotating impeller, which works by pushing air against the walls of the compressor, creating centrifugal force, and hence compressing it. This compressed air is then used to increase efficiency of electrical generation from solar panels and thus reduce costs.
