Due to the rapid growth of the solar module recycling market, the capacity of solar backplane expands very rapidly. The new capacity of enterprises with competitive advantages digests very quickly, while the utilization rate of existing capacity of enterprises without competitive advantages is relatively low. In addition, the capacity utilization rate of Suzhou Saiwu is far more than 100%, reaching more than 200%. It can be seen that the current production capacity of the company can not meet the demand for solar backplane products in the downstream market. The company urgently needs to continue to expand its capacity and further expand the solar backplane market.
