Sandwich-prefabricated roof module for e.g. warehouse, has inclinedly bent region carrying photovoltaic element that is attached to water distribution unit connected with water supply for cleaning and cooling photovoltaic element

摘要

The module (1) has a set of sandwich roof elements (2.1, 2.2) with an insulation between an outer upper metal sheet and an inner lower metal sheet. The sheets form both side-inclinedly bent regions (BB) and horizontally bent edge regions (T). The roof elements lying adjacent to each other parallel to an axis forms roof width, and another set of sandwich roof elements (2.3, 2.4) forms roof length. The inclinedly bent region carries a photovoltaic element that is attached to a water distribution unit connected with a water supply for cleaning and cooling the photovoltaic element.
