Germany: Rohrdorfer has started operation of a new photovoltaic (PV) unit at its Rohrdorf cement plant near Rosenheim in Upper Bavaria. The rooftop PV installation comprises 1000 modules, covers around 2000m2 and has a peak output of 400kW. The construction time of the solar panels took five weeks. Modules supplied by Hecker Solar were installed by Elektro Ecker.
The cement plant has produced around one third of its electricity requirements via a waste heat recovery unit since 2011. Rohrdorf Group aims to generate 30% of its electricity from renewable sources as a whole by 2033.
