Photovoltaic system

Photovoltaic systems were installed on the roofs of the buildings belonging to Friedr. Lohmann GmbH at the end of 2010. The systems, consisting of 3142 thin-film solar modules with a total output of 243.51 kilowatts/peak, were mounted on three large, flat roofs with a total area of 3000 m². The forecast annual output of 200,000 kilowatt hours is enough to supply a neighborhood with 50 four-person households with power for one year. This saves 180 tons of CO² per year.
After starting to generate electricity using hydropower and recovering heat to heat water, Lohmann has been using the next environmentally friendly power source, the new photovoltaic system, since 2011. In other words : environmental protection and the careful use of resources are playing a greater and greater role at Friedr. Lohmann GmbH in our production processes and in determining how we make investments. In addition to the traditional steel business, the Ruhr valley is developing as a small, integrated power generation region through the use of hydropower, solar power, and heat recovery systems. This in turn means the steel from Lohmann is becoming "greener and greener".
