Now you can determine the solar efficiency of your roof
Date:10/17/2011

It is becoming more and more common to install solar panels on roofs in order to obtain green electricity, but not all roofs are equally suitable. Scientists from the University of Gothenburg, Sweden, have launched a tool that uses the actual conditions to determine the maximum possible magnitude of solar incidence - in a whole town, a neighbourhood, or a particular roof. The scientists have surveyed Gothenburg in a pilot project.

"The roofs structures of a town may be more or less suitable for the installation of solar panels, depending on such factors as how much a particular roof is shadowed by surrounding buildings and vegetation, the gradient of the roof, and the angle of incidence of sunlight. It is now possible for the first time to determine how much solar energy a particular roof will receive during the year", says Fredrik Lindberg of the Department of Earth Sciences at Gothenburg University.

The scientists at the University of Gothenburg have worked together with consultants WSP to develop a GIS system that can calculate the potential of actual roofs to produce energy from solar panels. The system is called "SEES" Solar Energy from Existing Structures and will be freely available to both companies and municipalities.

The new tool is based on computer-based geographical information systems (GIS) that collect, store, analyse and present geographical data. This means that the tool describes real roofs in the correct surroundings. The sun in the model illuminates the three-dimensional built environment and simulates how surrounding buildings, terrain and vegetation throw shadows.

The shadow effect can be calculated for each month or for a complete year, and this means that certain parts of a roof may turn out to be unsuitable for collecting solar energy, even though the roof has both optimal direction and gradient. In this way, it is possible to calculate the total solar radiation on each part of a roof s
