The photovoltaic assembly is connected with two parallel guys through a connecting piece, the two parallel guys are positioned above the fish belly type photovoltaic cable truss to form a complete stress system, the structural form can realize the span of 70-80m, and the photovoltaic assembly is applied to some sewage treatment plants. The structural form has good rigidity in a truss plane, but the rigidity outside the plane is weak, and as the photovoltaic panels have certain inclination angles, the photovoltaic panels can generate large horizontal displacement when lateral wind load acts, and the structure is easy to generate lateral instability along with the increase of span, so that the requirement of ultra-large span of more than 100m is difficult to meet.
Therefore, it is necessary to design a photovoltaic support system which can meet the ultra-large span of more than 100 m.
