Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors.
A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky.
Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system manufacture such as silver may constrain further growth in the technology. Other major constraints identified are competition for land use. The use of PV as a main source requires energy storage systems or global distribution by high-voltage direct current power lines causing additional costs, and also has a number of other specific disadvantages such as variable power generation which have to be balanced. Production and installation does cause some pollution and greenhouse gas emissions, though only a fraction of the emissions caused by fossil fuels.
BIPV (Building Integrated Photovoltaics) is the future of solar energy generation. The development of solar glass and now solar tiles means that people will soon be able to build solar PV systems into the fabric of their homes, rather than tagging them on later. This often makes for better aesthetics.
One of the critics’ biggest reservations about traditional solar panels is that they are ‘ugly’, so their ability to blend in with the roof is one of the most promising innovations of solar tiles. They are a solution for homeowners living in listed property or conservation area where planning permission makes it harder to install conventional solar panels. We have even seen examples of solar tiles have being installed on Grade 1 listed properties.
Indoor Photovoltaics in Photovoltaic Industry
Gain Solar is a an carbon neutral solutions expert company established in 2007, which it is the daugher company of Yingli Group. It can provide the building photovoltaic-integrated (BIPV) green material, we envision a world where solar energy is generated by any surface touched by the sun.
As the new design solution makes possible Zero-Energy Buildings or Positive-Energy Buildings, without any compromise on architectural safety and aesthetics. Gain Solar BIPV products include solar facades, solar glass, solar roof tile, siding, greenhouses, railings, and more. These systems have frameless modules, hidden mounting, homogeneous surfaces, and can feature the appearance of any material or colour.
As the prodeesinal BIPV R&D and sales company, we under the support of four National R&D and innovation platforms, including the State Key Laboratory of Photovoltaic Materials and Technology and the National Key Laboratory of Energy Photovoltaic Technology. Ten(10) billions RMB in R&D funds, cultivated over 2,000 professionals in related fields, and launched a total of 12 Generation of BIPV products, hundreds of photovoltaic + products, applied in thousands of PV green buildings. Also Gain Solar have accumulatively applied for 292 patents, edited and participated in the compilation of 16 various standards, the number of patent authorizations and participation in standards ranked first in the industry .
