Suitability of roofs for use of solar energy

The map shows the degree of suitability of roofs for the use of solar energy, together with the potential yield. For this purpose the course of the sun throughout the year is simulated and the level of solar radiation reaching the roof is calculated. The suitability map currently incorporates around half the inventory of roofs in Switzerland. It is expected to encompass all roofs by the middle of 2019.
