Description

Technical Field

[0001] The utility model relates to the technical field of agricultural facilities, in particular to an integrated BIPV photovoltaic greenhouse for green farms. Background Technique

[0002] The photovoltaic greenhouse for green farms is an intelligent facility integrating agricultural production and clean energy power generation. By combining photovoltaic technology with the greenhouse structure, this system can not only provide an ideal growth environment for crops, but also convert solar energy into electricity to meet the energy needs of the greenhouse itself and even transmit the excess electricity to the power grid. Such a photovoltaic greenhouse for green farms can effectively reduce the dependence on fossil fuels, reduce greenhouse gas emissions, and enhance the sustainable development ability of agriculture. Especially in response to climate change and energy conservation and emission reduction, the photovoltaic greenhouse provides a new development direction for modern agriculture.

[0003] However, most of the existing photovoltaic greenhouses for green farms adopt the method of installing photovoltaic modules on the greenhouse ceiling through brackets. This non-integrated design with the separation of photovoltaic modules from the greenhouse has many deficiencies. First, the bracket design of the photovoltaic modules is prone to blocking natural light, resulting in uneven illumination inside the greenhouse, affecting the photosynthesis of crops, and thus affecting the yield and quality of crops. In addition, due to the additional load of the brackets and photovoltaic modules, the overall structural weight of the greenhouse increases, which may pose challenges to the structural strength of the greenhouse against wind, snow, etc. The bracket installation also occupies a part of the space at the top of the greenhouse, reducing the aesthetic degree of the greenhouse. In view of this, we propose an integrated BIPV photovoltaic greenhouse for green farms. Content of the Utility Model
