The combination of photovoltaic and agricultural development can enable the composite utilization of photovoltaic power generation on agricultural land,with plastic greenhouses in agricultural facilities being more widely used.To achieve the function of photovoltaic power generation in truss arched plastic greenhouses,the layout position of photovoltaic panels laid on the greenhouse framework is determined based on actual production conditions,and the load on the greenhouse framework is calculated.This article used ABAQUS finite element software to conduct three-dimensional modeling of greenhouse structures and finite element analysis of the greenhouse skeleton before and after renovation.The results showed that before the renovation,the photovoltaic panels were directly installed on the plastic greenhouse framework,and the safety effect was poor in windy and snowy weather;After the renovation,a 20.5 kg photovoltaic panel can be directly installed on the plastic greenhouse of the truss arch,which can be used safely.The reinforcement method used in the renovation can be applied to other areas with a basic wind pressure of 0.39 kN/m2 and a basic snow pressure of 0.66 kN/m2.
