[0002] At present, the photovoltaic power generation industry is developing rapidly. In my country, after nearly ten years of development, the application of the photovoltaic industry has gradually moved towards an agricultural photovoltaic development model combined with agricultural projects. The agricultural photovoltaic industry is a new photovoltaic system project that combines photovoltaic power generation with agricultural production, rooftop solar power generation, and agricultural production in the greenhouse. It is a new model for the development of modern agriculture. It combines photovoltaic power generation, agricultural production, ecological protection and sightseeing tourism, and uses rural landscapes, agricultural production activities, agricultural ecological environment and ecological agricultural management models to increase the unit output of land and increase farmers' income. The most widely used application of the agricultural photovoltaic industry is to lay photovoltaic modules on the roof of agricultural greenhouses to form a combination of photovoltaic greenhouses, photovoltaic modules generate electricity, and agricultural production is carried out in the greenhouse. After the photovoltaic modules used in the existing agricultural photovoltaic greenhouses are directly installed, they can only ensure that the greenhouse has the basic function of rain and snow protection, and photovoltaic power generation can be carried out at the same time to maximize the use of resources and increase ecological and social benefits.

[0003] According to the "Insulated Photovoltaic Roof Structure for Agricultural Greenhouses" disclosed in Chinese Patent Publication No. CN106386264A, the roof of the agricultural photovoltaic greenhouse is laid after the thermal insulation material and photovoltaic components are pre-assembled, replacing the original installation method of installing thermal insulation materials after the photovoltaic panels are laid. This not only ensures the rain and snow protection function of the photovoltaic components, but also ensures that the laid roof has the function of thermal insulation, meets the requirements of agricultural greenhouses, and greatly expands the scope of use of solar cell components as building structural materials. It is a new high-tech technology that integrates low carbon, energy saving and environmental protection. The present invention adopts profile installation, which is conducive to large-scale production and standardized installation. It is applied to agricultural greenhouses, which can not only ensure the ecological requirements of agricultural greenhouses, but also ensure the photovoltaic power generation effect. It has both green and environmental protection characteristics and is conducive to the development of ecological agriculture.
