cocu®PV
BOEHME® SYSTEMS cocu®PV - Multi-dimensional formable photovoltaic element and thereby provides almost unlimited creative potential for craftsmen and architects.
With the BOEHME® SYSTEMS cocu®PV-Element the system provider for metal building shells introduces a unique product to the global market with which architecturally demanding building geometries and organically shaped building shells can be cladded. At the same time, the multi-dimensional formable (cocu = complex curved) photovoltaic element (PV-Element) for solar energy that is industrially applied to the shingle by vacuum-lamination makes ecological construction possible without an additional element for the roof and facade cladding.
In cooperation with a German producer of photovoltaic products and based on the know-how of experienced engineers as well as master craftsmen of the BOEHME® SYSTEMS Vertriebs GmbH the company developed a new kind of product with the following characteristics:
complex curved:
- multi-dimensional forming of the cocu®PV-Element has been made possible without giving up the PV-functionality
- makes ecological construction with architecturally demanding building geometries possible
- organically shaped building shells are possible
- almost unlimited creative potential for architects
cocu®PV-Element is a building shell … no additional elements for the roof/facade necessary:
- industrial production (vacuum-lamination) which garanties a high quality standard
- no additional adhesive bonding of PV-cells
- no undesired dissolution of PV-cells
- no additional material (glue) necessary … significant weight reduction
All Light Performance (ALP):
- even under unfavourable weather conditions electricity will be produced
- energy generation is not limited to hours of sun
