Solar heating

Arcon-Sunmark - the world's largest solar heating plant in Silkeborg, Denmark.

The solar heating plant and the optimisation of the town's district heating plant are the first phase of Silkeborg Municipality's ambitious objective of producing solely CO2-neutral heating in 2030.

The plant consists of 12,436 solar panels of 12.6 m2 each which together gives a solar panel field of 156,694 m2. On a sunny day during the summer months, 2.7 million litres of water an hour circulates through the 850 rows of solar panels which are connected to the district heating plant via 1.2 kilometres of district heating pipes. The solar heating production may cover the annual heating requirements for 4,400 households or 20% of the overall heating requirements in Silkeborg.
