Large Scale Solar Pv

Building-integrated Photovoltaics

Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with BIPV modules as well. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. These advantages make BIPV one of the fastest growing segments of the photovoltaic industry.

History

PV applications for buildings began appearing in the 1970s. Aluminum-framed photovoltaic modules were connected to, or mounted on, buildings that were usually in remote areas without access to an electric power grid. In the 1980s photovoltaic module add-ons to roofs began being demonstrated. These PV systems were usually installed on utility-grid-connected buildings in areas with centralized power stations. In the 1990s BIPV construction products specially designed to be integrated into a building envelope became commercially available.

Forms

Building-Integrated Photovoltaic modules are available in several forms.

Building-integrated PhotovoltaicsFlat Roofs

The most widely installed to date is a thin film solar cell integrated to a flexible polymer roofing membrane.

Pitched Roofs

  • Modules shaped like multiple roof tiles.
  • Solar shingles are modules designed to look and act like regular shingles, while incorporating a flexible thin film cell.
  • It extends normal roof life by protecting insulation and membranes from ultraviolet rays and water degradation. It does this by eliminating condensation because the dew point is kept above the roofing membrane.

Building-integrated PhotovoltaicsFacade

Facades can be installed on existing buildings, giving old buildings a whole new look. These modules are mounted on the facade of the building, over the existing structure, which can increase the appeal of the building and its resale value.

Building-integrated PhotovoltaicsGlazing

Semi-transparent modules can be used to replace a number of architectural elements commonly made with glass or similar materials, such as windows and skylights.

Building-integrated PhotovoltaicsTransparent and Translucent Photovoltaics

Transparent solar panels use a tin oxide coating on the inner surface of the glass panes to conduct current out of the cell. The cell contains titanium oxide that is coated with a photoelectric dye.

Most conventional solar cells use visible and infrared light to generate electricity. In contrast, the innovative new solar cell also uses ultraviolet radiation. Used to replace conventional window glass, or placed over the glass, the installation surface area could be large, leading to potential uses that take advantage of the combined functions of power generation, lighting and temperature control.

Another name for transparent photovoltaics is “translucent photovoltaics” (they transmit half the light that falls on them). Similar to inorganic photovoltaics, organic photovoltaics are also capable of being translucent.

Geo Green Power have provided professional and yet friendly service...extremely helpful at every stage, always answering the smallest of queries promptly. All workmen have been informative, polite and helpful. We would definitely recommend them to anyone considering installing solar panels. We wish the company all the best!

We found your service efficient and enquiries polite and considerate. I would definitely recommend your services to anyone who is looking for solar, in fact we have another farm building which will be sorted after Christmas, and would think we will be contacting you again. Thank you once again.

Thank you for all your hard work. Everything was completed efficiently and professionally and I’m now saving and making cash thanks to my solar PV system. I like checking my meter just to see how much money I've made! Solar panels are a great investment and I’m recommending Geo Green Power to everyone I meet.
