The general production process is different, the material selection is different, and the service life is different. For example, if new recycled materials are used or mixed with other non polycarbonate materials, the service life will be three to five years, depending on the amount of mixed materials. Pure high-quality imported polycarbonate materials, such as Bayer or GEsabic raw materials, can generally be used for more than ten years.

A ten-year warranty refers to a 6% decrease in transmittance and a change in yellow index of less than 6% within ten years. This is an indicator that plastic does not age excessively. This means that the physical and mechanical properties of good solar panels will decrease very little after 10 years, and it will not affect their usability. The use of solar panels abroad is generally more than 10 years old.

The seven layer diamond shaped structure solar panel produced by Qiancheng Plastics has good transparency, low thermal conductivity coefficient, and a lifespan of the solar panel. The service life of the solar panel adopts advanced production technology and is manufactured using world-renowned brand Bayer raw materials, fully ensuring the effective use of product quality, with a lifespan of more than ten years. Due to its light weight, long lifespan, and high tensile strength, solar panels can meet the requirements of wind and snow resistance through a simple steel frame structure. They have a long lifespan, are aesthetically pleasing, and reduce repetitive construction and investment. Therefore, they are currently the preferred product to replace original plastic panels or glass skylights.
