The photovoltaic (PV) ventilated façade curtain wall and roof
system are a product with undeniable aesthetic value and unbeatable
in terms of heat insulation that generates free electricity from
The generated electricity can be translated directly to the mains
supply system, thus being marketed to the large suppliers, or be
used for personal consumption (isolated system).
The thermal surrounding methods can result in a 25-40% reduction of
the energy consumed by a building.
Depending upon the orientation of the façade, building location,
and the photovoltaic technology implemented, the electricity
produced by our system in just one square metre can vary between
20-40 kW/h per annum; sufficient energy to supply up to 10,000
hours of light from 20W energy saving light bulbs.
In addition to the obvious environmental benefits, in countries
where the sale of electricity is regulated and incentive based,
through an obligatory subsidy from the electrical companies, one
metre squared of ventilated roof can generate a net benefit in its
lifetime (25 years) of more than 1000 Euros.
From a financial point of view, depending upon the type of building
and its location, our ventilated façades and roofs can achieve an
Internal Return Rate (IRR) greater than 25% and an outstanding
Solar Photovoltaic Facade Curtain Wall - Solar PV Facades -
Conventional Solar Photovoltaic (PV) Panels can be fixed to the
external walls of buildings with brick or block exteriors, using
one of the aluminum or stainless steel bracketing systems to
connect. Purists would not consider this to be true Building
Integrated Photovoltaics as, in such cases, the Solar Photovoltaic
(PV) Panels are merely ‘stuck on’ and do not replace an essential
material that would otherwise be required in the building process.

Solar Photovoltaic (PV) Facades – Façade Curtain Wall Systems
There are two main building facade systems that readily lend
themselves to the incorporation of Solar PV technology: Rainscreen
Cladding (Ventilated Facade) type and Curtain Walling type.
Increasingly, Solar Photovoltaic Panels are being incorporated into
the construction of new buildings as a principle source, or an
ancillary source of electrical power. Solar PV Panels can also be
incorporated into existing buildings where wall cladding materials
are being substituted.
Solar PV Facades Curtain Wall - Rainscreen Cladding
(Ventilated Façade Glass Curtain Wall)
Rainscreen cladding systems were primarily developed in the Europe
for the refurbishment of high-rise concrete framed buildings,
particularly apartment buildings and office blocks etc. Rainscreen
cladding system is ideally suited to new buildings but is also
widely used for the renovation of older high-rise buildings with
poorly performing building envelopes. Rainscreen cladding
construction allows the refurbishment process to be carried out
while the building is still occupied.
Solar PV Facades - Curtain Walling Systems
Curtain walling systems are a well established technology, used in
numerous prestigious projects like city centre offices and hotels.
Curtain walls are assembled from non-structural elements and form
the outer skin of the building. They are designed to be airtight
and to resist wind and weather. Apart from their self-weight,
curtain walls do not carry any vertical loading but rely for
support on the building's structural floors and columns. A curtain
wall sustains some horizontal wind loading which is also
transferred to the main structure.
Curtain walls are lightweight and assembled using aluminium or
stainless steel framing, infilled with transparent or opaque infill
panels. Transparent panels are usually double or triple glazed
toughened sheet glass. Opaque panels can be constructed with
insulated coloured glass, ceramic tiles or insulated metal units.
Solar PV Facades - Glass Bonding
Laminated glass used in architectural products incorporates a
protective resin bonding layer, typically Polyvinyl Butyral (PVB),
positioned between two panels of glass. The bonding process takes
place under heat and pressure. When laminated under these
conditions, the Polyvinyl Butyral interlayer becomes optically
clear. When sealed together the glass sandwich behaves as a single
unit and looks like ordinary glass.
Solar PV Facades - Glass Sheets
In the manufacture of solar pv glass panel, the photovoltaic
circuit is formed on a sheet of glass, using thin film deposition
and patterning techniques. Polyvinyl Butyral and a second sheet of
glass are then placed directly on the circuit. The lamination of
this sandwich encapsulates the circuit, protecting it from the
external environment. Electric current is extracted from the module
at a sealed terminal box that is attached to the circuit and then
converted to alternating current electricity (AC) by an inverter.
Solar PV Glass consists of solar cells that are built into
transparent double and triple glazing units. Solar PV Glass can
easily be integrated into roofs and curtain walling facade systems.
Using thin film Solar PV Cells in curtain walling can result in an
economical use of solar energy and encourage creative architectural
design as well as engineering.
