AMORPHOUS
Coating over a layer of flat glass (CVD)
Visual Light Tr: Dark, 10, 20, 30%
Efficiency 5% - 10%
Greater energy production (kWh) at the same installed power (kWp)
Better behavior under the presence of shadows / overcast (tilt, orientation)
Low temperature coefficient – performs
well under high temperature
Unobstructed views

By add-ons we refer to other configurations for the photovoltaic glass that,depending on the performance desired for the project, may be required.
Spacers are a typical add-on to improve the U-value of the PV glass unit;counting on an double pane unit and considering the coatings applied, thephotovoltaic glass can reach U-values as low as 0.13 BTU/h*Ft2*Fº.
Typical spacer thicknesses are ¼”, ½” and 10/16”, depending on the insulationrequired. Air and Argon gas fills are commonly requested.

2. ONYX SOLAR APPROACH FOR BIPV
Architectural glass which besides providing the building with the same passive properties as a
conventional glazing, it also generates free electricity from the sun.
It is therefore, the only building material available in the market that provides your building a return on
the investment.
ARCHITECTURAL GLASS THAT GENERATES ELECTRICITY
• MATCHES THE
ARCHITECTURAL GLASS
SPECIFICATIONS
• ENVIROMENTAL BENEFITS:
AVOIDING CO2 EMISSIONS
• ECONOMICAL BENEFITS:
ENERGY GENERATION

CENTRAL OCULUS
The pattern of the cells opens up
to a circular oculus with lines of
Morse code that spell out a
poem. It is an excerpt of Gifts of a
River by E.D. Blodgett, a former
Edmonton Poet Laureate
