Abstract
The present disclosure concerns a photovoltaic sandwich panel (1) comprising a photovoltaic element layer (2) provided between a protective front layer (3), and a fiber reinforced back layer (4), wherein: the protective front layer is formed from a compound comprising a first thermoplastic polymer (PI); and the fiber reinforced back layer comprises a second thermoplastic polymer (P2) with a fibrous filler material (F). The disclosure further concerns a method for manufacturing a photovoltaic sandwich panel and an assembly of said panels.
Claims15
A photovoltaic sandwich panel comprising a photovoltaic element layer provided between a protective front layer, and a fiber reinforced back layer, wherein:
- the photovoltaic element layer comprises photovoltaic cells,
- the protective front layer is formed from a compound comprising a first thermoplastic polymer,
- the fiber reinforced back layer comprises a second thermoplastic polymer with a fibrous filler material,
- the photovoltaic sandwich panel has a mass per surface area in a range between 2 and 10 kg/m2,
- the photovoltaic cells are encapsulated in a thermoplastic polyolefin (TPO) that has a melting temperature lower than a melting temperature of the protective front layer and the fiber reinforced back layer, and
- a thickness of the second thermoplastic polymer is reduced along a line across the panel and respective ends of the fiber reinforced back layer on either end of the line remain connected to each other via fibers of the fiber reinforced back layer.
