Existing district heating networks in Europe often supply heat in a temperature range of 80 °C to 120 °C. To decarbonise these systems, solar thermal has a great potential. Up to now, high-performance flat-plate collectors and evacuated tube collectors are state of the art for the integration of solar heat into district heating (DH) networks and are well developed and described. However, other collector technologies, such as parabolic troughs and linear Fresnel collectors, can provide heat in a wider temperature range and might offer higher efficiency and advantages over the state of the art, like tracking and the possibility to control the heat yield.
