Large-scale solar district heating plants in Danish smart thermal grid: Developments and recent trends

This study reviews the development of large solar district heating plants in Denmark since 2006. Large solar collector fields are very popular in district heating systems in Denmark, even though the solar radiation source is not favorable at high latitudes compared to many other regions. Denmark is not only the biggest country in both total installed capacities and numbers of large solar district heating plants, but also is the first and only country with commercial market-driven solar district heating plants.
