Building integrated photovoltaics - technology status

Building integrated photovoltaics modules provide a high degree of design possibilities and additional functionalities in combination with the plain electricity generation well known for standard photovoltaic installations. Consequently, the specialized know-how to understand building integrated photovoltaics, properly design and manufacture them requires much more than the electrical knowledge developed and applied in standard photovoltaic systems. Expertise of building physics and building regulations are also required on a high level. As building integrated photovoltaics modules are usually custom designed, typical electrical design and simulationols cannot be used without modifications, while deeper insight of complex shading influences and specialized overall system design are advantageous. Authors of this publication were involved in well over 1000 building integrated photovoltaics system designs and developments, and their experiences are shared. Recurring questions, issues and mistakes of various building integrated photovoltaics projects are touched, whereas special emphasis is provided on building integrated photovoltaics engineering procedures, system design complexity, as well as shading issues and differentiation of shading according to their origin

Fassadenelement und Verfahren zu seiner Montage

The invention relates to a facade element (1), comprising a sheet-like element (10) with a first side (11) and an opposite, second side (12) and at least one carrier layer (20) with a first side (21) and an opposite, second side (22), wherein the first side (21) of the carrier layer (20) is connected to the second side (12) of the sheet-like element (10), wherein the carrier layer (20) has a larger surface area than the sheet-like element (10). Furthermore, the invention relates to a method for mounting a facade element which comprises a sheet-like element (10) and at least one carrier layer (20) which is not completely covered by the sheet-like element (10), wherein the method comprises at least the following steps: producing a supporting structure (30, 35) on the building and fastening the facade element (1) to the supporting structure (30, 35) by inserting at least one fastening means (17) into the part (25) of the carrier layer (20) that is not covered by the sheet-like element (10)
