This project - the largest roof installation in Germany of its kind - was contracted by Sunova AG, Grasbrunn, who is partner in several roof projects throughout Europe, acknowledging the outstanding performance of Sunfilm modules with respect to their application on flat roofs. Sunfilm provided its module Model Q, which represents the smallest out of five available formats. The roof installation in Dornstetten will have to challenge strong winds and heavy snow loads but is perfectly prepared for such exposure as the SUNOVA MCG 2.1 System has already proved its superior mechanical stability under such conditions in the laboratory, in wind tunnel tests and in the field. The PV power station is planned to produce 2.4 times more power per year than Weinmann Aach AG used in 2008. This provides enough capacity for an increase in power requirement as the company expands. Sunfilm’s thin film tandem junction technology is particularly well suited for commercial roof installations because the modules maintain their excellent energy efficiency, even when installed in parallel roof orientations. This horizontal orientation avoids negative effects of shadowing by adjacent rows of PV panels. Therefore, modules can be put closer together increasing the number of panels per roof area. In addition to this orientation advantage, the modules also maintain their efficiency at lower irradiation conditions, appropriate for most regions in Germany. Another important aspect is the environmental benefit as the PV system in Dornstetten reduces climate-active CO2 emissions by yearly 540 tons. |
