Are your solar roofs really efficient?

University of Gothenburg

The University of Gothenburg has launched a revolutionary tool, that can determine the highest possible solar incidence magnitude on a roof, a town or the whole city. The scientists have used the city of Gothenburg for this pilot project. The University of Gothenburg has partnered with WSP consultants to develop this GIS system, called ‘SEES’ ( Solar Energy from Existing Structures), that can measure solar roofs’ potential to produce solar energy from the panels.

The model works on the principle that specific roof structures may or may not be suitable for using solar panels. This depends on the sunlight the system receives and how much is shadowed by the surrounding buildings and vegetation. Using the tool developed by the University, it will be possible to know the amount of solar energy that can be produced by a solar roof in a specific setting.

SEES is based on the GIS system (geographical information system). This system collects, stores, and presents data. SEES can be used to show real solar roofs incorrect surroundings. The pilot project has used Gothenburg as its primary model, but the same can be applied for municipalities where the data is available.
