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.
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.

FAQ
Why is oil‑free compressed air critical for solar cell manufacturing?
In solar cell production, even trace oil contamination (above 0.01 mg/m³) can cause:
Micro‑cracks during wafer cutting due to uneven cooling
Poor adhesion of anti‑reflective coating (SiNx) in PECVD chambers
Defective screen printing – oil causes paste smearing or open fingers
Reduced module power output by 2–5% when oil residuals remain on cells
Therefore, most photovoltaic (PV) manufacturers require ISO 8573‑1 Class 0 (oil‑free) air for all process‑contact applications.
What type of air compressor is best for a solar module lamination process?
Lamination requires clean, dry compressed air for both vacuum generation (to remove air between EVA and glass) and pneumatic press actuation. The recommended solution is:
Oil‑free rotary screw compressor for continuous 24/7 operation
Vacuum pump (often integrated) for lamination chamber evacuation
Refrigerated dryer with pressure dew point at +3°C to prevent condensation
Fine coalescing filter (0.01μm) to ensure no particles deposit on EVA sheets
Many factories also use a dedicated receiver tank to stabilize pressure during the pressing cycle.
How does compressed air pressure affect solar screen printing quality?
Screen printing of silver/aluminum paste is extremely pressure‑sensitive.
Too low pressure → incomplete paste transfer (thin fingers, high series resistance)
Too high pressure → screen mesh damage, paste bleeding, or cell warpage
Pressure fluctuation → inconsistent finger width and height across a batch
Typical requirement: ±0.1 bar stability at the dispensing head.
A VSD compressor + adequately sized receiver tank + pressure regulator at point of use is standard. Some advanced lines use a closed‑loop pneumatic control with real‑time feedback.
Can we use an oil‑injected compressor with filtration for solar wafer cleaning?
Only with extreme caution. Wafer cleaning baths (RCA clean, HF etching) require air‑free or ultra‑pure air to avoid contamination.
If you already own an oil‑injected compressor, you must install:
• Coalescing filter (0.01μm)
• Activated carbon tower
• Catalytic converter (for oil vapor removal to <0.003 mg/m³)
• Desiccant dryer for −40°C dew point
However, the total cost of such filtration is often higher than switching to an oil‑free compressor. Most new solar plants specify oil‑free from the start to eliminate risk.
