Five German bioenergy villages added solar fields to their district heating systems in 2018. It was a significant increase over 2017 and 2016, when only one larger field was commissioned once a year. Each village benefits from 100 % solar energy in summer, which leaves time to overhaul their plants fired by biomass. The field shown in the photo consists of 3,000 m2 of flat plate collectors and was installed by boiler manufacturer Viessmann in Mengsberg in middle Germany.
