As spring officially begins in the northern hemisphere, we finally get to enjoy more hours of daylight than darkness. The days are getting longer and the sun is going down later. And Melanie Graf is celebrating by taking to the roof! Our photovoltaic expert has just signed off on the construction work for a roof-mounted solar power plant at a major industrial customer in Oranienburg (Brandenburg). The plant has an installed module output of 120 kWp (inverter output 110 kWp) and will be commissioned in April. 100 percent green energy for the whole company!
