Solar Potential - roof cadastre

Dominik.Uhe
The SUN-AREA research project provides the proof: About 20% of Germany’s roof tops is suitable for solar energy use. It could cover the complete power requirement of homes throughout Germany. This corresponds to more than 100 times of that used today.
SUN-AREA calculates the solar power potential of each roof area, each city and each county or district. With geographical information systems, the solar potential of all roof areas is precisely calculated fully automatically on the basis of aircraft scanner data. This is done by calculating the angle of the roof, its alignment and shade. Solar suitability, potential power output, CO2 reduction as well as investment volume are calculated thereby for each subarea of a roof and made available to all in an interactive map on the Internet.
The SUN-AREA method was developed be a team of researchers led by Prof. Dr. Martina Klärle. (www.sun–area.net)

70,000 roofs were inspected in Osnabrück, a pilot city. An extract:
