Solar Cadastre
A solar cadastre is an inventory of each roof in a town, commune or region, its orientation, inclination and irradiation as well as the corresponding solar potential.
Based on Meteonorm
In the field of irradiation data, Meteotest has developed the worldwide leading climatology database Meteonorm. This software allows to retrieve irradiation data for a typical year for any location worldwide. Due to the high density of the measurement station network as well as the inclusion of satellite data, data quality is especially high in Switzerland. Since 25 years, Meteonorm has been an excellent base to determine the solar potential.

GIS modeling
In collaboration with our GIS department, we offer solar cadastres for towns, communes and regions based Swisstopo's high resolution digital terrain model DOM. For each point on every roof, we calculate local shadowing (trees, neighboring buildings) as well as the topographic horizon. The terrain model's high resolution even allows taking complex roof structures into account.
Benefits
Our solar cadastres can be utilized to assess a town's or region's potential for the production of solar power. Additionally, the data can be combined with additional information, e.g. protected historical buildings, in order to further refine the potential analysis. Furthermore, a yearly solar power production can be calculated for single houses and even single roof areas.
This information can be used internally (authorities, power companies) or published in a web application in order to sensitize house owners and citizens. Try out our demo application!
