Solar Thermal Energy

Solar thermal energy, heating water with energy from the sun, is an entirely renewable, reliable and cost-efficient energy source. A typical residential solar water-heating system reduces the need for conventional water heating by two thirds; making such installations an attractive option for both homes and businesses.

Since the 1970’s Danish companies have worked on developing solar water-heating systems in large-scale applications and smaller systems for the home. There are currently more than 40.000 single-household solar water heating systems in Denmark.

Solar energy is a viable energy source for district and block heating applications. There are a number of demonstration plants in Denmark with roof-mounted as well as ground-mounted collector arrays. The largest district heating solar plant in Europe is 20,000 m2 and is located in the Danish town of Marstal.
