Substantially two-dimensional construction element

摘要

A construction element (29) which extends in two dimensions comprises a solar energy converter member (1) which also extends along and defines one surface of the construction element (29). The construction element (29) further comprises a building construction member (30) which extends along the construction element (29) and defines the second surface thereof. At least a part of the solar energy converter member (1) is integral with at least a part of the building construction member (30) whereby this integral part both contributes to the requirements for solar energy conversion as well as to requirements for constructions.

1. A substantially two-dimensional construction element for roof-construction, comprising
a solar energy photovoltaic converter panel comprising photovoltaic cells and a panel substrate, the photovoltaic converter panel extending along and defining one surface of said construction element and providing for solar energy conversion; a building construction member, extending along and defining the second surface of said construction element and providing for construction requirements; wherein the photovoltaic converter panel is integral with the construction member and is one layer of a layer stack comprising the construction member,
the layer stack including a core material layer of at least one of a foam, a honeycomb, a fabric and a glass wool, having a thickness of between 50 mm and 30 cm, and having a thermal conductivity coefficient between 0.1 W/mK and 0.001 W/mK to provide for thermal roof insulation,the layer stack further comprising a front surface layer of one of a composite material and of a metal and having a thickness of between 0.25 mm to 5 mm chemically bonded on said core material layer, andthe construction element being constructed so that provides at least predominantly the requirements of the roof-building construction with respect to thermal isolation and mechanical toughness and rigidity.
