| The
photovoltaic glass-panels, known as BIPV (Building Integrated
PhotoVoltaics), replace the construction material in buildings
while, at the same time, they transform the solar radiation
to electricity, saving energy. The entire surface of the building
(20m2->1000 Watt) produces electricity using the daylight. They
can function along with the local grid, or, individually. They
consist of a fine layer of amorphous silicon that is embodied
between two high clearance glasses of total width 7mm. They
are produced using high standard quality techniques
and they have long life endurance. They present lower construction
cost and higher efficiency to cost ratio comparing to the mono
and poly crystalline PV while they have higher efficiency at
cloudy sky.
The BIPV's fulfill environmental conditions since they have
the ability to produce clean and noiseless electricity; economic
conditions since they render energy autonomous buildings; and
aesthetic conditions since they are able to fit in the architectural
design. |

The
PV can be used as construction elements in buildings of modern
and classic architecture in combination with the conventional
glasses in south, east, and west building facades, in suitably
shaped roofs, or in special applications if the architectural
design permits it. The BIPV coating in buildings that are designed
according to the principles of the bio-climatic architecture
is of great importance since we can achieve minimum energy consumption
and maximum economy.
See the 4Times Square Building. |

| The
application of the BIPV obtains even greater interest with the
issuance of the Regulation for the Rational Use and Saving of
Energy by the Greek Ministry of Environment and Public Works,
which will be taken into consideration for the issuance of
the building's permit. |

Upholding
Arrangements of the Photovoltaiv Glass-Panels
The standard upholding arrangement includes an aluminum U profile
on the backside of the PV. Also, the arrangement can be done using
an aluminum frame with which we will accomplish the following upholding
arrangements:
The panel's level is parallel to the wall's level.
The panel's level is perpendicular to the wall's level.
The panel is placed on the roof, etc.
In addition, the aluminum frame can embody a PVC border to decrease
the tensions created between the glass and the aluminum.
