Over the last seven months, a lorry has gone to Arcon-Sunmark in Skørping 455 times in order to unload solar panels for the world’s biggest solar heating system in Silkeborg
The system consists of 12,436 solar panels for each 12.6 m2, a complete area of 156,694 m2. On a sunny day in the summer half, 2.7 million litres of water circulate through the system every hour. Through 1.2 kilometre long district heating pipes, the system connects to a heating plant.
- One fifth of the heat consumption in Silkeborg is now covered by solar heat; a figure we have been proud of contributing to in collaboration with Silkeborg Forsyning. The project is living proof that redistribution to sustainable energy does not have to be a long and difficult process. It can be realised quickly and effectively, says Søren Elisiussen, the managing director at Arcon-Sunmark.

Silkeborg Forsyning and Arcon-Sunmark entered into agreement forthe construction of the world’s biggest solar heating system in February 2016. The actual work began in May at Sejling Hede. And at the end of December, the system was put into operation.
