We've got our own QC operators responsible for carrying out quality tests conforming to the international standards. However, if customers ask for a third-party quality test for commercial solar panels, we give our full support to satisfy your needs. The tested aspects are involved in products' technical specifications, measurements, the contents and formula of related raw materials, etc. The employees working for the third party engage in the whole spectrum of QC activities and are responsible for checking the quality. They can also provide quality reports for us and customers.
