In the application and promotion of fiberglass reinforced composite products in the photovoltaic field, the introduction of new materials and new technologies may cause users to have doubts about the reliability of new products, and owners have relatively low understanding and recognition of new products. To realize the supplement and replacement of traditional metal materials by composite products, it is not only necessary to expand users and owners' understanding of new products and display the advantages and performance of the products themselves, but also to carry out testing, certification, and demonstration of products and raw materials, and to further evaluate the products. The reliability and stability are demonstrated and verified to reduce application risks and gain user acceptance.

Testing and certification serve as a stepping stone for composite products to enter the photovoltaic field. While self-certifying, it also needs to be combined with the requirements of the owner, the needs of component companies, and production line assembly requirements. Testing and certification involve many aspects, taking composite photovoltaic frames as an example. Material performance, basic product performance, overall component performance, empirical verification, etc. all require testing and certification. It is particularly important to carry out joint certification of raw materials, products and component factories. Joint certification can also reduce certification costs.
