Comparition for the Performance of Roof Photovoltaic Modules in Xi'an
For the application of roof photovoltaic,there are mainly two types:BAPV and BIPV."BIPV"refers to Building Integrated Photovoltaic,also known as"construction type"and"building material type"solar photovoltaic buildings.As a part of the external structure of the building,it not only has the function of generating electricity,but also has the function of building components and materials,which is more integrated.."BAPV"refers to Building Attached Photovoltaic,also is known as"installation type"solar photovoltaic buildings.Its main function is to generate electricity,and its overlap with building functions is relatively small..Taking the roof photovoltaic module grid-connected power generation system in Xi'an as an example,this paper analyzes the power generation characteristics of different photovoltaic modules in the roof photovoltaic application through the power generation performance and module temperature changes of BIPV and BAPV in different seasons and weather conditions.The test results show that BIPV modules has better power generation performance,good anti-dust effect,low risk of hot spots and higher reliability.
