jailcd2023006: Study on the optimization strategy of photovoltaic skin of building roof based on parameterized design

Abstract

The concept of low carbon in building design has been deeply rooted in people's minds, and the integration of photovoltaic building brings a good opportunity to combine the use of renewable energy and morphology of buildings. The technical means of converting solar energy into electricity through photovoltaic panels plays a positive role in reducing the energy consumption of buildings, so the design method of combining the building skin with photovoltaic devices is widely used. In this paper, we investigate the relationship between the incidence angle of the sun and the power generation capacity of PV panels at different times of the day when the building is located in a region that is favorable for PV power generation and use the tilt angle of PV panels at different locations as a variable to analyze the power generation capacity of PV panels under different tilt. The genetic algorithm is used to establish a skin optimization procedure, and the photovoltaic skin form with the highest power generation efficiency is selected, which improves the solar energy utilization rate of the photovoltaic skin and serves as a reference for the parametric design method of the photovoltaic power generation device structure of the building skin.
