Towards sun power made for roofing

Started in November 2010, PV-GUM is a 4.5 year demonstration project involving eight European
partners, 6.4 M€ funded by the European Commission under the 7th Framework Programme. The main
scope of the PV-GUM project is to fully integrate flexible thin film PV modules in the roofing membrane
