The retaining ring used in the photovoltaic industry mainly refers to the retaining ring material in the solar photovoltaic cell module. The retaining ring is an important accessory used to protect the photovoltaic cell module, which is usually located between the frame and the glass of the photovoltaic cell module, and plays the role of fixing and sealing.
The main functions of the retaining ring include:
1.Ensure the stability of the module: The retaining ring can effectively fix the frame and glass of the photovoltaic cell module, preventing loosening or damage during transportation and installation.
2.Provide sealing protection: The retaining ring can form a sealing layer at the edge of the PV cell module, preventing moisture, dust and other contaminants from entering the inside of the module and protecting the normal operation of the battery.
3.Slow Component Aging: Retaining rings can also provide an additional layer of protection to slow down the aging rate of components and extend their service life.
Retaining rings used in the photovoltaic industry are generally made of plastic materials such as polypropylene or polyethylene, which have excellent weather resistance, corrosion resistance and high temperature resistance. In addition, the retaining ring needs to be resilient to ensure stability in the event of changes in the temperature of the component.
In conclusion, retaining rings play an important role in photovoltaic cell modules, protecting the safety and performance stability of photovoltaic cell modules while extending their service life.
