Simulation and Analysis of Production Capacity of Polyhedral Photovoltaic System Based on Building Facade
The aim is to efficiently utilize the spatial resources of the building facade,to increase the solar power generation potential of the building facade,and to reduce its own energy consumption in order to improve the overall energy performance of the building.A polyhedral structural PV system is designed to be applied to a building facade,and the system is modeled using PVsyst software,which simulates the system capacity of four orientations,east,south,west and north,respectively,under the climatic conditions of the cold region,and compares with the capacity of the flat structural PV system under the same conditions,and calculates the yearly energy consumption of the building by taking a near-zero-energy building as an example of a building that has been applied with two different structural PV systems on the the facade of this building and compare the energy contribution of the two PV systems in this building.The conclusion is that the annual power generation of polyhedral structure PV system in the four orientations is improved compared with that of flat structure PV system,with the biggest improvement in the north orientation,similar in the east and west orientations,slightly smaller in the north orientation,and the smallest in the south orientation,and the solar power generation potential of the building facade can be effectively improved through the reasonable design of PV system,which can satisfy the part of the building's energy consumption demand,and achieve the self-generation and self-consumption of energy to reduce the building's energy consumption.
