BIPV Roof & Facade
BIPV Roof & Facade
Building Integrated Photovoltaic
A Building Integrated PhotoVoltaic (BIPV) system of glass on glass PV solar panels that are fitted on an interlocking weatherproof framework to provide a secure and effective rainscreen cladding system, which can be fitted on both vertical (façade) and inclined (roof) surfaces, generating electricity from both surfaces. Patents have been applied for as regards the mounting systems for both the façade and roof surfaces.
Insulation materials — non-flammable mineral wool — can be installed between the inner building surface and the external solar panels to improve building thermal performance. These opaque materials in the wall build-up would preclude the possibility of allowing light to enter the building, whereas the panels have transparent spaces in between the cells that would allow sunlight to penetrate the building (with about 7.5% daylight transmission) if desired. The solar electric panels can be mixed with clear glass panels to increase light penetration to the level required for such features as canopies, conservatories, passages or stairways.

ZED Power BIPV panels are testing at the Building Research Establishment (UK)
The finished design was tested and certified by the Building Research Establishment to meet with the appropriate BS (British Standards) and EN (European Standards) for roofing products and before being released onto the market.
The solar panels meet safety standards for overhead glazing — steel balls the size of a man’s head have been dropped on the panels from a height of 6 meters during tests at the BRE without causing any damage. The BIPV panels have full TÜV (Technical Inspection Association) certification and UK MCS (Microgeneration Certification Scheme) accreditation.
