Second, the building is an art
The first is a BIPV building construction, it is the architect of the art, the music equivalent of musicians, painters of a famous painting, and for the buildings, the light is his soul, thus demanding the building of light and shadow. But the common PV modules are mostly used for Gyrosigma ultra-white glass tempered glass, frosted glass block line of sight with its Gyrosigma role. If the BIPV components are installed in the building of the tourist office, this position requires light transparent, then we should use double-sided glossy production of ultra-white glass, tempered glass components, used to meet the building’s function. Meanwhile, in order to save costs, the back of the glass panels can be smooth with ordinary glass. A building is the key point is the appearance of the building effect, sometimes subtle lack of coordination can not be tolerated. But the common PV module junction box generally stick to the back panels, junction boxes larger, it is easy to destroy a sense of the overall coordination of the building is not usually acceptable for architects, so BIPV building junction box eliminates the need or request hidden, then the bypass diode junction box without protection, to consider other ways to protect it, you need to bypass diodes and cables hidden in the wall structure.

Common PV modules generally exposed in the component cable below, BIPV building the cable requirements of photovoltaic components all hidden in the wall structure.
Third, the building structure and electrical properties of PV modules with
In the design of BIPV panels to consider when building their own voltage and current of photovoltaic system equipment selection, convenience, but the building’s facade may be a number of sizes, geometric forms of varying composition between the components that will cause voltage and current is different this time can be considered to partition the building facade and adjusting grid, BIPV components close to the standard components to make electrical properties can also be used in solar cells of different sizes to meet the requirements of sub-grid to the maximum Limit results to meet the building facade. Also, you can corner on a small number of cells are not connected into the circuit to meet the electrical requirements.
Fourth, clever use of solar energy in the building
Solar energy for the protection of the environment has created favorable conditions, so many architects exploit the use of solar energy construction of solar buildings.
1, solar wall: The United States invented the solar wall construction experts, is installed in the building of the wall outside the black hole a thin layer of aluminum, the wall can absorb the radiation to 80% on solar energy. The air is sucked into preheated aluminum plate, pumped through the wall inside the building, which can save the energy consumption of central air conditioning.
2, solar window: two German scientists invented windows with light and heat regulation. One is the solar temperature control system, the surface of the window during the day and capture the building heating, and then passed to the solar wall and floor space for storage, at night it came alive again; the other is automatically adjusted the amount of sunlight entering the room, the same as the color sunglasses, according to the room temperature setting, windows or become transparent or become opaque.
3, Solar Housing: German architect plug more. Horizon Hills built a track in the sun on the base of the solar rotation housing. The housing is installed on a disk base, driven by a small group of solar electric motor gear, the Housing Foundation in the circular orbit to 3 cm per minute, the speed of rotation with the sun. The system tracks the sun’s power consumption is only the power house solar power 1%, and the room generally can not solar power is equivalent to twice the rotation of the solar house.

What is BIPV?
BIPV meaning:Building Integrated Photovoltaics .
It means that they are built/constructed along with an object. They are also planned together with the object. Yet, they could be built later on. Due to specific task cooperation of many different experts, such as architects, civil engineers and PV system designers, is necessary.
