Nowadays, the development of photovoltaic industry is hot. It is not only the 'sunshine bank' on the roof of users, but also adapts to different construction requirements by virtue of its own advantages. It is an embodiment of building components and widely used in greenhouses, daylighting and sun room, etc. In fact, Not limited to the roof of the building, more novel 'climb the wall'.
'Photovoltaic Climbing' still uses the traditional installation mode of PV modules and PV brackets, the only difference is that the components are hung on the external wall. The installer will hang the PV on the wall. The pure color PVP not only increases the appearance of the wall Degree, slightly inclined point of view can also guarantee the efficiency of photovoltaic power generation systems to ensure the economy of photovoltaic projects.
In fact, 'Photovoltaic Climbing Wall' is a new type of integrated photovoltaic building design. The main ways to make the PV on the wall are 'PV curtain wall', 'PV tile' and 'PV tile'.
Photovoltaic building integration means that the solar photovoltaic system is designed, constructed and installed at the same time as the building.Power as a part of the external structure of a building can not only have the function of generating electricity, but also have the function of building components and materials, and even enhance the beauty of a building, Buildings form the perfect unity.
Photovoltaic curtain wall
The photovoltaic curtain wall, which is pasted on the glass, is embedded between two pieces of glass and can convert the light energy into electricity through the battery. It is actually a high-tech product that integrates power generation, noise insulation, heat insulation, safety and decoration. New building materials.
China invested 30 billion yuan to build China's tallest skyscraper - Wuhan Greenland Center, with a height of 636 meters and a total of 131 floors, which is expected to be completed by 2018. The building has about 21,000 building curtain walls all using electricity-generating Solar glass. When built, the curtain wall has a 'breathable' function that allows the building to fully absorb sunlight, minimize energy consumption and achieve 'green energy efficient buildings'.
Solar tile
The photovoltaic tile combines the architectural efficiency and power generation efficiency of traditional tiles to achieve close photoelectric architectural integration. The photovoltaic tile has the appearance of achromaticity, delicate and smooth color, uniform inner and outer materials, so that the entire roof not only keeps the traditional tile construction Style, but also to ensure the consistency of the roof height before and after, increasing the visual beauty of the house.
For example, Fuyang District is the first experimental site for PV power generation in China. In 2014, the village unifiedly installed photovoltaic power generation tiles that will generate electricity in 289 new residential areas. Each household adopted 100 20-watt / Ceramic tile, single household installed capacity of 2,000 watts.
Photovoltaic tiles
Photovoltaic ceramic tile is a new development of photovoltaic technology in the production process, not only to maintain the function of solar power generation, and its power generation is stronger, colorful colors make the building look more aesthetic.
For example, 12,000 sea-blue solar photovoltaic tiles were installed on the roofs and walls of the new campus in Copenhagen, Denmark as Denmark's largest integrated photovoltaic building project, generating 300,000 kWh of electricity per year and satisfying half of the school's electricity demand.
The integration of green elements in buildings has become the mainstream trend of the current development of buildings. Photovoltaic 'on the wall' is undoubtedly a big pioneer in the installation of new PV installations. The mature application of 'climbing wall' PV has largely proved the vastness of photovoltaic power generation prospect.
