Abstract: In order to develop a stable, durable and lightweight PV bracket, based on a PV bracket pilot project, this paper designs a polymer matrix composite PV bracket. Based on the wind load, snow load, self-weight load and earthquake load, the strength of the key component and the nodes have been checked according to calculation. At the same time, the feasibility of the application of the composite PV bracket was verified by the wind tunnel test of PV bracket and the 4000 h multi-factor aging properties of composite materials.
