Solar district heating (SDH) plants are large-scale solar thermal plants delivering heat via district heating systems. District heating and solar thermal energy play an important role in the energy transition of the heat sector in Europe. Find out more about the advantages of this combination here.
Solar district heating solutions exist for different types of integration. The collectors can be ground-mounted or installed on roofs or infrastructure.
Find out more about the technology and how to implement it in the SDH Guidelines.
Growing SDH market
Solar district heating is a tried and trusted technology. Operators and industry professionals have amassed over 20 years’ experience in developing, operating and maintaining SDH systems. The last decade has also seen a rising interest in the commercial use.
So far, 300 plants above 350 kWth of capacity have been put into operation in Europe. The market has experienced a boom in Denmark and sound growth in several other places, such as Austria, Germany and Sweden. The total installed capacity amounts to 1100 MWth and the mean market growth over the last 5 years was more than 35% annually. Other European countries have begun to follow suit and new markets have started to develop.
