The city of Rjukan does not see the sun for about six consecutive months in the winter period as it lies deep in the valley. In the city of Rjukan in Norway, our customer placed a system of heliostat mirrors on the mountain slope, in close cooperation with the local authorities. The heliostat mirrors will illuminate the town square in the winter period. Our mirrors enhance not only the conversion of sunlight to clean electrity, they literally bring the sun to the people!
