Porth authority Mallorca
Installation of a photovoltaic skylight as part of the refurbishment of the Balearic Port Authority building in the Port of Majorca.
For this 180 m2 (1,937 sqFt) skylight, a low-emissivity (low-e) amorphous silicon glass was chosen, which also features an air gap to improve the insulation of the building even further and thus to prevent the undesirable greenhouse effect within.

The glass modules measure 2,200 mm x 1,300 mm (7.22 x 4.26 Ft) and feature a degree of semi-transparency of 20% . Thus, the glass is able to permit the ingress of daylight while filtering out the harmful UV and IR radiation, which prevents the overheating of the building interior and significantly improves the comfort of its occupants.
With an installed power capacity of 6 kWp, this skylight is capable of generating 8,700 kWh per year and of powering 500 lights for 4 hours each day, while it prevents the release of nearly 6 tons of CO2 into the atmosphere.
