Research On The Structure And Application Of Agricultural Multi-span Photovoltaic Greenhouse

It is urgent to solve the existing problems by using green energy as energy shortage and environmental degradation was aggravated.The photovoltaic industry has been an important component of the new energy.With the decline in the price and technological maturity of photovoltaic modules,the photovoltaic greenhouse goes into people’s lives gradually.This paper mainly analyzed and researched the problems existed in external structure,internal system and photovoltaic layout of photovoltaic greenhouse,and improved the design of external structure,facilities and growth monitoring system of the greenhouse by optimizing the current problems and combining the advantages of multi-span photovoltaic greenhouse.The photovoltaic panels that placed on the roof can transform solar energy into a power supply that was suitable for different environments and could be equipped with battery for storing electric energy.Then,the converted power could supply the internal usage of greenhouse directly,while the surplus power could be incorporated into the national grid for subsidies.First,by researching the related domestic and foreign information through the literature data,this thesis analyzed the research background,purpose and significance;By introducing the general situation and characteristics of the building photovoltaic greenhouse agriculture,this thesis analyzed the constructional problems existed in the auxiliary equipment of the building photovoltaic greenhouse structure from outside to inside,and elaborated the influencing factors of building greenhouse from the geography,climate,and the cost;In the structure,it analyzed from the unit division of greenhouse,the performance and the design principle.And in view of the existing problems,this paper put forward the optimal design method by optimally designing the structure of photovoltaic layout and system;Then finding the problems through the requirements analysis of the internal auxiliary equipment,and thus it can improve and design the main temperature and humidity monitoring system and growth monitoring system;Finally,it analyzed the case application of photovoltaic greenhouse,and chose the application case of photovoltaic greenhouse in Zhukov city.It can play a beneficial role in energy saving and emission reduction by understanding the development conditions,the project of the external structure,the internal auxiliary equipment,and analyzing the efficiency of photovoltaic power generation,and therefore verifies advantages of the photovoltaic multi span greenhouse.
