Abstract:
The present teachings relate to a solar roof forming element for forming a solar roof of a building, comprising an extruded, elongate polymer roof plate, element coupling means, at least one solar panel covering the roof plate, panel coupling means for coupling the solar panel to the roof plate, comprising a first coupling part at a first side of the roof plate and a second coupling part at a first side of the solar panel, said coupling parts configured such that they mutually couple as a result of a movement of the solar panel relative to the roof plate, wherein in a coupled state a movement of the solar panel away from the roof plate in a direction perpendicular to the roof plate is blocked. The present teachings further relate to a combination of such solar roof forming elements, to a building, and to a method of forming a roof.
Abstract:
The invention relates to a photovoltaic module comprising (a) a front layer (1) arranged on the sunlight facing side of the photovoltaic module, wherein the front layer (1) comprises a first polypropylene composition, comprising a polypropylene, wherein the transmission of the front layer for light in the wavelength range of 350 nm to 1200 nm is on average at least 65% as compared to a situation without the front layer as determined according to ASTM D1003-13, (b) a sealing layer (2,4) which at least partly encapsulates a plurality of photovoltaic cells (3), wherein the sealing layer (2, 4) comprises a polyolefin elastomer composition comprising an ethylene-α-olefin copolymer and (c) a back layer (5), wherein the back layer (5) comprises a first reinforced polypropylene layer comprising a second polypropylene composition comprising a polypropylene and optionally a reinforcing filler, wherein the sealing layer is arranged between the front layer and the back layer.
Abstract:
A bulkhead (110) for separating an engine compartment (112) and a passenger compartment (114) including a support structure (320) including at least one reinforcement member (324) and a body (322) supported by the reinforcement member (324), a thermally insulative component (330) supported by the support structure (320), and an acoustic resonator (370) defining a plurality of openings that extend along a first direction from the thermally insulative component (330) toward the first resonator side and terminate at a location between the first resonator side and the second resonator side. The acoustic resonator (370) includes a plurality of cells that each defines a respective first open volume that is in fluid communication with at least one of the plurality of openings.
Abstract:
