Probing for PV façade systems made of lightweight plastic modules with reversible fittings for new and old buildings (PV-FAS_light + easy)

Probing for a new, simple, cost-effective and building-integrated PV facade system made of plastic PV modules through initial investigations for fixing technology, for building physics, for fire protection and for electrical engineering concerning the usability, the areas of applicability and the yield and application potentialfor new buildings and for existing buildings.

Short Description




Starting Point / Motivation

Building PV is desirable for energy reasons. PV modules are desirable for building and façade integration for architectural reasons. This is currently very rare because the overall design is expensive and because the rigid module sizes can hardly be integrated into the facade planning. However, as soon as special formats become necessary, all profitability ends.

Therefore, PV systems are desirable...

  • ... which have simpler substructures,
  • ... which are easier to produce in different formats,
  • ... where faulty individual modules can be easily replaced,
  • ... which provide a good PV yield is achieved and
  • ... are able to cover economic investment costs;
  • ... which can be integrated in the new building as well
  • ... which can be retrofitted to existing buildings.

Contents and Goals

With this exploration project, products and technologies available on the market have recently been merged into a new system. These are the lightweight PV modules embedded in plastic systems and the new Velcro closure system for separable thermal insulation composite system façades.

Together they have the potential for a simpler, lighter and more cost-effective PV façade system to be tested for applicability, yield potential and safety.


Questions concerning the following points are being clarified in the context of this project:

  • for fixing technology,
  • for fire protection and
  • for electrical engineering

Therefore, initial investigations on fastening technology, electrotechnical concepts and, above all, building physics and fire protection (determination of fire load, fire behavior, etc.) should be carried out in order to estimate the application potential. Subsequently, a follow-up project is to be prepared with real applications and monitoring.

Expected results

The extected results are an estimation of the application potential according to technical, economic and building regulations criteria and the preparation of a succession project with real applications.
