Double-glazing windows are now required by many governments worldwide for energy efficiency. These glass units usually have a gas between the panes that helps to cut down on unwanted heat transfer. But Israel“s SolarOr has taken a step forward and has sandwiched between the two panes of glass an actual energy generator, instead of just a substance that helps to conserve energy. This energy innovation was on display at the Intersolar event in San Francisco this month. SolarOr inserts tiny faceted solar photovoltaic cells facing the sky at the top of a honeycomb inside the glass. The solar glass efficiency or electricity generated per square meter is said to be better than most BIPV, (Building Integrated PV). According to SolarOr, this honeycomb glass can produce 155 Watts per square meter, a little less than typical rooftop PV panels, but there are no extra installations to be made to a normal building. While generating energy, their glass also cuts heat transfer and lets 40% of the light through, therefore meeting most government requirements for energy efficiency, as for most double pane windows. SolarOr“s curtain wall module is designed for climate control and solar energy harvesting, combining energy production with heat insulation, sun protection and robust structure.
