The Designand Study On Building Integrated Photovoltaicte Generate Electricity System

Energy, materials, information and biotechnology is 4 pillar of modern civilization,The material foundation of human survival and development and the motive force of human engaged in various economic activity is energy.Along with the coal, oil and natural gas fossil fuel resources are unsustainable consumption and the need to protect the ecological environment, and development of new energy to promote world energy structure of the shift, new energy technologies mature gradually will bring revolutionary change of industrial areas. Solar energy as the one kind of new energy mainly use form for solar-thermal conversion, photoelectric conversion and actinic conversion technology.From the point of view of sustainable development,the solar photovoltaic power generation building integrated system research will be a very potential direction.This paper firstly introduces the system design principle, steps and content; Then introduced region geography, climate and solar radiation; Then designed the solar photovoltaic energy building integrated system: system power form and composition, array design, stents design etc; Finally the system major equipment were chosen: solar photovoltaic panels, inverter, controller, etc.Use of the designing system performance test, and its application in effect are analyzed, and the results show that is as follows:(1)The max temperature difference of solar panels surface and environmental is 37.9℃,the min is 12.8℃,the average is 20.55℃;(2)Daily the max capacity is 100kw.h,the min is 22 kw.h,the average is 56.53 kw.h;(3)The max photovoltaic array efficiency is 17%,the min is 4%,the average is 11%;(4)The max inverter conversion efficiency is 95.49%,the min is 79.91%,the average is 88.49%.
