Solar photovoltaic (pv) solar panel technology should be in the building

According to the solar panels and the way of building combined with the installation of different can be divided into photovoltaic building integrated ( Or photovoltaic Building Integrated, English name is Building Integrated PV, is ordinary BIPV) And photovoltaic building additional ( English for Building Attached PV, abbreviation

according to the solar panels and the different methods of construction and installation, can be divided into photovoltaic Building integrated ( Or photovoltaic building integrated, English name for the building integrated photovoltaic (pv), commonly known as BIPV) And photovoltaic building subsidiary ( English name for construction subsidiary photovoltaic, BAPV) 。 From the perspective of architecture and technology, photovoltaic building integrated has the following advantages: ( 1) Installed on the roof of the idle or on the wall, requires no additional land or other facilities, suitable for use in the densely populated place. ( 2) To on-site power generation, electricity in situ, and within a certain distance to save the investment in the power plant in power grid transmission. For networked family system, pv array power can be provided to the load of the building or sent to the grid. The summer peak power demand can be alleviated. ( 3) Because of pv array installed on the roof, walls and other peripheral protection structure, solar energy is absorbed into electrical energy, greatly reduces the outdoor temperature, reduce inside the wall heating and cooling load, 0 + save energy, to ensure the quality of indoor gas 0 +. ( 4) Avoids using normal fossil fuel power generation of air pollution and waste residue, which in the current and future under the condition of strict environmental protection is more important. ( 5) Due to the assembly of photovoltaic cells, photovoltaic array is easy to install, generation capacity can be arbitrary choice. Green electricity generated from thin film solar cell technology for building insulation, greatly improving the building comfort, make the building energy saving and photovoltaic power generation to achieve effective complementary ideal state. BIPV modules can effectively use of irradiation on the surface of the building, solar power, reduce indoor solar radiation by 60%; Double silver glass of lighting area, however, can be highly transparent at the same time, the heat transfer coefficient by 21%. In general, the average room temperature was reduced by 5 - Eight degrees, thus reducing the north-south temperature difference, the winter warming and summer cooling, and keep warm and heat insulation. Due to the change of room temperature, empty is expected to reduce power consumption by 15%.
