On summer 2015 two small-scale demonstrators have been realized and installed on the roof over the research center of Tegola Canadese headquarters, in Vittorio Veneto (Italy). The roof it’s usually used as a testing center, in which several products of TEGOLA production and R&D have been installed to analyse behaviour of the building components with ageing.This roof is a challenging demosite to analyse photovoltaics, since it is a south east exposed roof, with 18% of slope. The test roof consist in two separate stands of BiPV products, parallel installed by torch on the roof. No retroventilation have been provided to BiPV, that have been installed in direct contact with the rear bituminous waterproofing substrate. The roof covered with BiPV is a concrete roof, that have been covered with 3 layers of  membrane (2 old layers, one the brand new installed on purpose for this demo site).

Goal of this activity is to demonstrate the  BIPV solar shingle conceived for an easy-mounting and on-site customization. It consists of a durable glazed panel (containing crystalline solar cells provided by the partner Meyer Burger) integrated in a waterproofing back-sheet layer made of a bitumen-based membrane. Two different outdoor test-facilities have been installed, both in Vittorio Veneto (Italy) and in Lugano (Switzerland), in order to gain experience from installation in different conditions, nailing on a wood structure (Lugano) rather than torching on on a waterproofing membrane (Vittorio Veneto). Those procedures are both forecasted in the Athens big scale roof demosites. Collection of output data on the prototype electrical efficiency, measured in real conditions, allows comparing the behavior of the solar shingle with existing products on the market, installed in the same conditions, as a comparison benchmark.
