Abstract
Under the new situation of achieving emission peak and carbon neutrality goals,distributed PV power generation technology and application scenarios have ushered in a new period of development.This paper focuses on the research of installing the distributed PV power station on the roofs of self owned small office building.Taking a roof distributed PV power station in Shanghai as an example to evaluate and analyze the solar energy resources in the location of the PV power station.Then,the PV power station is designed from the aspects of PV module selection,PV bracket and foundation selection,PV string design and access system.The power generation capacity of the PV power station is calculated by considering the characteristics of the PV modules,geographical location and other factors.Finally,benefit analysis is carried out from the aspects of economic benefits,environmental benefits and social benefits.The research results show that the cumulative power generation capacity of the roof distributed PV power station over 25-year full cifecycle is about 2215 MWh,with an average annual power generation capacity of about 89000 kWh.When the proportion of PV self use rate is calculated at 50%,the economic benefits of PV power generation from the PV power station over 25 years are approximately 1.591×106 yuan,and the investment recovery period is 4.7 years.The total CO2 reduction of this PV power station over 25 years is about 1530.1 t,with an average annual CO2 reduction of about 61.2 t.The construction of the distributed PV power station using roof of self owned office buildings not only fully utilizes idle roof resources,but also achieves insulation,heat insulation,energy conservation and noise reduction functions.It also has certain economic,environmental and social benefits,and is a good model for the development and utilization of renewable energy.关键词
