PHOSTER project consists in the development of highly efficient eco-designed building integrated photovoltaic (BI-PV) roofing element using innovative and greener manufacturing process. The project intends to strongly contribute in the expansion and the promotion of the solar energy (a green energy) and to address the climate change environmental problem.
A prototype of a new universal solar steel roof envelope will be designed, manufactured, installed and monitored during the project's 48-month timeframe.
In order to support the further expansion of the solar energy and to limit as much as possible its environmental impact, the PHOSTER project aims at prototyping a new universal eco-designed roofing envelope including flexible thin film PV modules using steel as substrate and its related innovative and optimized manufacturing processes.
Five environmental targets are set for the project:
1 - Reduction of up to 30 % of the Global Warming Potential with respect to a framed PV module installed on a metallic roof, representing 46 kg CO2 eq./m².
2 - 15% reduction of the carbon footprint and the primary energy use for manufacturing CIGS modules, thus leading to a savings of 15.8 kg CO2 eq./solar cell m². This will be achieved by reducing the energy required by 50% during the selenisation process, and by introducing energy efficient management of the solar cell installation.
3 - An increase of 1,5 % of the kWh/kWp produced with respect to currently available BI-PV modules on steel roofs, mainly achieved by reducing the shadow effect on the steel profile and by optimising the PV module global design
4 - To reduce the amount of the rare toxic element cadmium by 20 to 25 g per m² of PV module (100% reduction in comparison with existing technologies).
5 - Achievement of an eco-designed BI-PV Roofing envelope, of which at least 85% (in weight) is recyclable. With a foreseen weight of the PHOSTER envelope of 10 kg/m² a minimum 8.5 kg/m² of material can be recycled at the module’s end of life.
The European Commission is co-financing the PHOSTER project
The LIFE programme is the European Union’s financing programme for the environment. Its general aim is to contribute to the development and deployment of the EU’s environmental policy and regulation by co-funding pilot or demonstration projects with high European added value.
