NOVELTY - The system has water flow chutes oriented along a slope of an inclined roof covering, and drainage chutes oriented transversal to the water flow chutes. The water flow chutes and the drainage chutes comprise drainage flaps (7), drainpipes (8) and collecting T-squares (9) that are arranged and connected between each other to prevent water infiltrations between photovoltaic solar panels (5), to collect the water dripping on the panels and to assure water flow towards the bottom of the covering.    USE - Sealing system for an inclined roof covering of a construction (claimed) e.g. edifice such as vehicle canopy.    ADVANTAGE - The system assures sealing of the covering without using underlying sealing elements and without covering the panels, thus facilitating the assembling and mounting of the panels on a bearing structure. The configuration of the system efficiently protects electrical connection elements arranged on a lower surface of the panels against humidity and wrenching risks. The drainage flaps, the drainpipes and the collecting T-squares are arranged and connected between each other to prevent water infiltrations between the panels, to collect the water dripping on the panels and to assure water flow towards the bottom of the covering, thus ensuring better recycling of the water. The design of the system is such that the panels are fixed easily and supported using bearing elements by conserving totality of surfaces of the panels exposed to solar radiation and by permitting perfect integration of the panels. The arrangement of the system reduces vandalism and theft risks of the panels and facilitates interventions on electrical connections during positioning of the panels.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a construction comprising an inclined covering.    DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a junction zone between panels of an assembly illustrating different elements of a sealing system and relative positions of the elements.
