The roof is formed by roof tiles (1) which are laid on a roof timberwork and which each have a cavity (7), in which means (13) for collecting solar energy are situated, the cavities being interconnected, through which a fluid flows pressurelessly and in free fall from the top to the bottom through the cavities of the roof tiles, over the associated absorbers and from one roof tile into the next lower roof tile, and in doing so absorbs heat from the sun and/or from the absorber. <IMAGE> |
