The Danish municipality of Roskilde installs a Skyline solar cell column.

In September 2017, the Danish municipality of Roskilde installed a Skyline solar cell column at a traffic calming zone at the driveway to the Danish town of Gundsømagle.

Roskilde Municipality has chosen to place a 6 meter high, self-sufficient solar cell column as an alternative to traditional lighting, because there was no access to a 230V electricity network in close vicinity.

This solution is a so-called Plug n ‘Play solution, where everything is mounted at the factory ready for the burial of the supplied concrete foundation. The battery box with a 2.4 KWh battery capacity is located underground next to the column to ensure easy access to the battery.

The column is fitted with 12 south-facing solar panels with a total maximum of 264Wp. The solar panels are installed vertically with 4 strings of 3 panels. The side of the column facing north consists of anodized aluminium.

The LED luminaire is of the type Siteco SL10 Mini, which has a brightness of 1520 lumens at the maximum level.

Energy production and lighting management are carried out by the PRIESS LCC control system. The advanced technology of the PRIESS LCC ”harvests” most of the solar panel’s energy during daytime and ensures the correct turn on and turn off of the LED luminaire during the changing seasons.
