The solution which Onyx Solar® has integrated into this new 16-storey building consists of the inclusion of photovoltaic glass on the façade and rooftop of the same, with a total of 439 m² (4,725 sqFt) of integrated photovoltaics with 20,61 kWp of peak installed power.
On the one hand, blue amorphous silicon glass of two different sizes were used for the main and lateral façades, featuring a low semi-transparency degree. On both façades a double-skin system is used, where the glass is installed on a metallic structure, forming a geometric pattern on the façade.
On the other hand, the panes integrated on the building rooftop are made of monocrystalline silicon and provide a peak power output of 28,08 kWp.
The installation of Onyx Solar®‘s photovoltaic technology at the Union National Bank enables the generation of over 61,000 kWh per year, enough to power 3,482 lights and to prevent the release of 41 tons of CO2 into the atmosphere.
