Suncell’s role is to develop, for each project, the best possible solution that takes into account the sometimes contradictory wishes and constraints of all stakeholders in an active building envelope project:

Type of constraint	Stakeholders / basis
Energy and financial aspects: Overall system cost (photovoltaic panels, substructure and electrical connection) Annual electricity production target	Client / project owner Architect General contractor Legislative/normative framework and applicable regulations
Constructive aspects: Aesthetics / visual appearance Integration into the building volume Fire safety, structural stability	Client/project owner and/or architect Local authorities Applicable regulations
Technical/industrial aspects: Production constraints Constraints due to standards Technical possibilities	Suppliers (glass, cells, etc.) Production lines: Prototyping in Switzerland (Suncell – Villeneuve/VD) Licensed production in the EU and China
