From New software calculates a city’s potential by Sven Ullrich & Craig Morris:

Researchers at the University of Göteborg in Sweden have come up with a new computer program to analyze the potential of solar power generation and solar heat for entire cities. The program supports a wide range of data formats.

Called Solar Energy from Existing Structures (SEES), the new software collects, stores, analyzes, and graphically displays geographical data for roofs to determine their suitability for solar arrays. It calculates both the angle of solar incidence and shading from trees and nearby structures. In addition to this data, the roof angle and climate data are included with a resolution of up to an hour. The program shows building roofs in their actual environment. In the model, the sun shines on the building’s three-dimensional surroundings to correctly reveal shading, which can also be calculated for individual months and the year as a whole.
