Description

Technical Field

The invention relates to the field of engineering design, in particular to a cadmium telluride photovoltaic and building integrated design method based on digital simulation.

Background

The photovoltaic building integrated technology is to seamlessly integrate the solar photovoltaic power generation system with a building, so that the building not only has the traditional building function, but also can generate electric energy through the solar power generation system. The development of this technology is of great importance for promoting sustainable development and coping with energy crisis.

Deepening the technical research of the integrated photovoltaic building is very necessary at present. Although the conventional photovoltaic power generation system has a certain power generation capacity, there are some disadvantages. First, the conventional photovoltaic power generation system requires solar energy to be collected by externally installing a solar panel, which requires a lot of space, and particularly for urban construction, the space is limited, so that difficulty and limitation are often faced in installing the photovoltaic system.

Second, conventional photovoltaic power generation systems are not compatible with conventional architectural styles in terms of architectural appearance, which may affect the overall aesthetics of the building, reducing the value and appeal of the building. Especially for special types of buildings such as historical buildings, cultural heritage and the like, the installation of the traditional photovoltaic power generation system can cause certain interference and damage to the protection and repair of the buildings.

In addition, the installation of the traditional photovoltaic power generation system also needs to carry out certain transformation on the building structure, so that the construction difficulty and cost are increased, the structural stability of the building can be influenced to a certain extent, and additional engineering design and construction measures are needed.

The patent application document with the application number of CN201710130935 discloses a photovoltaic building integrated arrangement design method, which comprises the following steps: carrying out solar numerical simulation analysis on a photovoltaic building by utilizing Ecotect software, taking the solar intensity of sunlight vertical to the surface of the building as effective solar intensity by considering the incident angle of the sunlight, accumulating the month effective solar intensity and the year effective solar intensity, and optimally selecting the arrangement position of the photovoltaic module in the building model according to the calculated year effective solar intensity distribution condition of each grid point of the building model. Drawbacks of this approach include: considering only sunlight intensity as an optimization index may ignore other important factors, such as shadow shielding, weather variation, temperature effect and the like, which have important influence on the performance of the photovoltaic system; whether shadow shielding of the photovoltaic module by the building itself and the surrounding environment is considered is not mentioned, and the shielding can have a great influence on the performance of the photovoltaic module, particularly in different seasons and times; no mention is made of specific photovoltaic module types, and the performance of different types of modules (e.g. monocrystalline silicon, polycrystalline silicon, thin films, etc.) under different conditions varies greatly, and should be optimally arranged according to the specific module type.

Therefore, it is necessary to provide a method for integrated design of cadmium telluride photovoltaic and buildings based on digital simulation.
