High-rise buildings in the application of solar pv benefits

Built in the application of solar pv five great affliction: the city than in rural areas, the difficult than monomer difficult, high-level engineering than low-rise residential exiting the difficult, than the difficult, both transformation than new difficult. High-rise buildings in the city’s construction and development in the proportion of increasing, because the roof area is small, people think hard placed solar energy collector, so the solar energy in high-rise buildings in engineering application is almost blank, most solar enterprise “afraid of heights” of developed countries, even the solar enforce policies and the application in high-rise buildings as “exceptions” processing. After LiMuRan after detailed investigation, felt deeply high-rise there are actually many favorable factors caused no attention.
Six advantage cracked high-rise building applied solar energy problems. Top roof have enough area can be installed collector, because top area of each layer of each building area more than the sum of 2 square metre, according to each collection hot area computation, in planar space for installation Angle of 45 degrees collector, and can meet the height is 40 layer building owners using solar gain life water needs, Users of high concentration of high-rise buildings, water can control complementary, theoretically, each with hot water 100 liters ~ 200 liters, but a lot of practice proved that every actual average water consumption for 60 litres ~ 80 litres, large system of central heating, collector area is reduced, Solar collector installed in high-rise building top, a parapet occlusions, public view see, a bit does not affect architectural style; High-rise buildings have a ready-made cistern and conduit well can use, compared with hotpvc film table cloth water storage tank open-air roof or underground equipment room placed and saves energy and piping systems decorate reasonable, compact solar system installation can avoid wearing wall, make hole, pipeline plugins, High-rise building daylighting condition is good, shining, won’t cause light pollution; High-rise building water supply from downward, without pressure, as long as the guarantee cycle can, water supply energy consumption is low, Collectors, cistern, piping not users home, elevator goes to the top floor bring convenience to installation and maintenance.
