Solar Tower & Server Hall
A vertical tower with solar panels (solar cells) on all four sides may seem strange as most sunlight comes from south.
But firstly: The daylight, even in cloudy conditions, makes the solar cells on all sides produce electicity.
And secondly: In northern countries the sun is low in the sky half of the year and then a vertical surface is struck by more sunlight.
And thirdly: This small tower has around 20 times bigger solar cell area than a horizontal solar cell would have on the foundation!
In the background to the right you can see a part of the Server Hall - a wooden climate-positive building that stores carbon dioxide. And all covered in solar cells!
A part of the exhibitions at the ETC Solar Park in Katrineholm.
