The light comes from three heliostatic mirrors by the name of Solspeil, which were installed on the side of the mountain around 450 meters above the square of the town.
The mirrors are able to capture the sunlight which doesn’t make it down onto the square and then direct it into the square. The mirrors are able to illuminate around 600 square metres and they are controlled by computers
This allows them to be able to track the sun as it moves across the sky. The mirrors move every 10 seconds and this ensures that the residents get sunlight in the square for the length of the day. - See more at: http://interestingengineering.com/the-huge-sun-mirrors-of-rjukan-shed-light-on-the-town/#sthash.eFpxCdfX.dpuf
