BIPV (Building Integrated PV) roofing
Technical field
The utility model belongs to area of solar cell, specifically, relates to a kind of BIPV (Building Integrated PV) roofing.
Background technology
The in the situation that in regenerative resource, fewer and feweri and environment pollution being more and more serious, the energy-conserving and environment-protective energy, is more and more subject to people's concern.Photovoltaic solar, as one of civilian clean energy resource, has been subject to upper to the lower support energetically to local government of country.
BIPV(Building Integrated PV(Photovoltaic), BIPV (Building Integrated PV)) be one of photovoltaic solar technological innovation, its principle is to adopt photovoltaic module to be directly used as roof panel, to replace traditional color steel roofing structure.
BIPV photovoltaic building does not need separately to account for soil, can also save the braced structures of photovoltaic system.Silicon solar cell is solid-state semiconductor device, no-rotary part when generating, and therefore noiseless, can not pollute environment; BIPV building can be generated power for their own use, and has reduced expense and the energy consumption of electric power course of conveying, has reduced transmission of electricity and point electric investment and maintenance cost.If make land used intensity of sunshine high, BIPV system, under certain condition also can be to mains supply except ensureing the interior electricity consumption of self building, and the peak power of releiving demand, has great social benefit; In the situation that air pollution is day by day serious, adopt BIPV photovoltaic building can stop the serious air pollution being brought by general fossil fuel power generation function, very important for higher today of environmental requirement and future.
The construction and installation of BIPV roofing photovoltaic have increased architectural appearance overall appearance effect.Well merging of building and photovoltaic module system, increase architectural its aesthetic appearance.At economic aspect, save the color steel of traditional roofing watt and parts procurement, save the pollution that energy consumption and solid waste are brought.Traditional color steel watt life-span is very short, exceedes certain time limit and just starts to get rusty, and need to again change roofing, and integrated cost drops into high; And BIPV photovoltaic roof, photovoltaic component frame all adopts aluminium alloys, and be 25 years service life, greatly reduced the generation of the situation of getting rusty, and improved application life.As time goes on, in the increasing situation of civilian and industrial electric weight, BIPV photovoltaic roof can self-supporting generate electricity, can well avoid peak of power consumption and allow the electricity stage, reduce the loss to enterprise, for personal little owner, the generating of BIPV roofing can be uploaded grid-connected, can continue to increase economic well-being of workers and staff.
Because BIPV roof building assembly is normally for roof or the wall face of building, therefore run into rainy weather, if draining in time can cause damage, the short circuit of photovoltaic module or open circuit, and then directly affect generating effect; And because the installation site of photovoltaic module is all at the outer facade of building, also can cause difficulty and danger to maintenance.
