Evaluation of PV Utilization Potential of University Building Roofs Based on PVsyst Software Simulation

Solar energy utilization is an important way to reduce energy consumption of university buildings and build a green low-carbon campus environment. With usually large and plain form, the roofs of college bulidin (CB) in universities may possess good basic conditions for PV utilization. To explore the actual potential of PV utilization of the roofs of existing FBC, this paper takes a FBC in a university in Xi'an area as an case for analysis. First of all, a CB close to the campus center with a moderate total area was selected as a typical research object; second, a roof PV utilization scheme was proposed based on the situation of the case building; third, PVsyst software was used for modeling and simulation, based on which calculation was conducted to evaluate the energy saving and economic benefits that the roof of the case building may generate; finally, the overall PV utilization potential of the roofs of all FBC in the university was calculated, limitations of this research were addressed and further researches was recommended.
