Our polycrystalline solar panels adopt the latest international manufacturing technique, selected and quality solar cells, and other materials. Under strict, scientific and systematic quality management, go through eight strict testing processes, these make the product quality up to international class.

 

1. Adopt efficient and well-known brand solar cells, use precision welding and 

      lamination process, inspect strictly according to relevant standards.

2. The tolerance of Peak power is ± 3%, average peak power is not below the

      quality requirement. Standard cells used in the test have to undergo rigorous

      testing, so test data is accurate and reliable.

3. High performance on product safety and environmental testing, the products pass

      the testing of many international and domestic authorities, and have been

        certificated.

4. 3-year warranty, power loss not more than 10% within ten years after ext

      factory, less than 20% within 25years.

 

All the technical parameters are at standard test condition AM=1.5  E=1000W/m²  Tc=25℃, and subject to actual production and final confirmation.
