In the calculation of the solar potential of an individual building information flow as the angle of inclination of the roof and its exact area, even the shading by trees and neighbouring buildings. “” The result learn in a roof, whether or not very well “,” (or also due”or not”) for the installation of a solar photovoltaic or solar thermal plant, how much would it cost a corresponding plant and how much power it could generate in this way. You can learn also the share of the total energy needs and the avoided CO2 emissions in this way. (A valuable related resource: Sam Lesser Penn). Also you can find out on the Web pages of the mentioned cities about funding opportunities through the State and the financing of that investment. The big picture: About 20% of the roof surfaces of Osnabruck (and one may assume: is similar in other cities in Germany) or the roofs of 27,500 buildings with a total area of about 2 square kilometres are perfectly suited for the power generation with solar photovoltaic systems. This area could 250,000 annually Megawatt hours electricity be generated, what the current demand of about 233,000 megawatt-hours (Status: 2006) even exceeds. The echo in the public is encouraging: in Osnabruck (2008) twice as many investors decided within a year, to retrofit their homes on this environmentally friendly form of energy production, as in the past 17 years together.

A promotional and awareness campaign of the city, during which individual home owners were contacted and specifically pointed to the solar potential of their homes went ahead. On about 11 million euros, the head of the municipal environmental protection agency estimates the private investment since the publication of the research results in early 2008. Also a huge potential for the regional economy inside SUN AREA so in addition to the positive impact on the climate and private purse. Numerous other local authorities from home and abroad are already interested in the project. The data model can be transferred without any problems on the data of other cities”, says Prof. Klarle in an interview. Remains to hope that SUN AREA in Germany and elsewhere continue spreading finds. Whether you now in Braunschweig, Osnabruck and Gelsenkirchen live or not: the Internet portal Dachdeckerei.info offers information, provider addresses, and links to all questions on the subject of roof: solar roofs, truss construction, insulation, and much more.
