The invention concerns a photovoltaic system for a sloping roof covered with roof covering panels (11, 12, 13). The system comprises panel-shaped photovoltaic modules (24, 26, 28, 30) which overlap like scales in the crest-gutter direction and lie on top of bearing elements (36, 38) which can be placed in the crest-gutter direction. To create a photovoltaic system which can be built in modular form into a roof covering consisting of small roof covering panels, it is proposed that: the width of a photovoltaic module (24, 26, 28, 30) should equal an integral multiple of the system coverage width of the roof covering panels (11, 12, 13); the length of a photovoltaic module (24, 26, 28, 30) should be greater than the greatest coverage length; the surface provided with photovoltaic cells should be shorter than the shortest coverage length of an adjacent roof covering panel (11, 13); one of the bearing elements should be provided with a stay (94) to brace a bearing element (90) closer to the crest on the bearing element (88) closer to it in the gutter direction at a height above the surface of the photovoltaic module (28) so as to be capable of sliding longitudinally; and an underlying covering element (32, 34) should be provided with a water course which can be positioned below the longitudinal edge of a photovoltaic module. |
