This solar project is an excellent example of the application of solar power for skylighting features. The administrative office of the city of Halle installed a thirty metre long skylight incorporating 28 solar panels located above a hallway. The architect’s brief was to produce a feature which utilised solar power while at the same time providing adequate natural lighting of the hallway below.

Because of the degree of inclination possible with skylighting features, the potential electricity output can be maximised. In order to ensure adequate lighting below, each skylight section was divided into three with the solar photovoltaics being deployed above and below insulating glass. The solar application also helps to prevent overheating of the hallway in the summer. The solar skylight generates 2,500 units of electricity each year. Information about the electrical system converting the solar power to mains power is provided for the occupiers and visitors to the building.
