NOVELTY - The panel structure has an interface apparatus (3) that can be disposed along the perimeter of a panel or solar panel, and can be positioned on a base between the tiles (12) of a pitched roof. The interface apparatus has an outer edge (3a) counter-shaped to the tiles to partly overlap the tiles so as to ensure watertightness and allow rainwater or the like to flow between the tiles and interface apparatus. The panel and interface apparatus are reciprocally connected to ensure the watertightness and allow rainwater or the like to flow.    USE - Panel structure for roofs. Can be used for the application of solar panels and photovoltaic panels on pitched roof (claimed).    ADVANTAGE - Provides an inexpensive panel structure, in particular a solar panel, that can be integrated visually with a roof covered with tiles or the like. Ensures the conventional functions of the roof and in particular the evacuation of rainwater. Ensures that the panel structure is capable of being integrated dimensionally with any type of tile, irrespective of the dimensions of the panel. Allows correct thermal insulation of the roof and correct air flow under and over the roof, preventing the sail effect. Allows rainwater or other atmospheric agents to flow on top of the covering without allowing water to pass to the inside. Ensures that the panels or solar panels maintain temperatures of below 30 degrees Celsius to achieve improved efficiency of the solar panels. Includes an interface apparatus that has the same aesthetic appearance as tiles of traditional type, while the panel is positioned on the same plane as the pitched roof , and therefore does not project or protrude from the surface of the covering. Ensures that the panel structure has a dimension that can be selected and can integrate dimensionally with any type of roof by suitable positioning of the interface components. Ensures that the panel structure is very simple, both to fabricate and to assemble, and presents low purchase and assembly costs. Ensures that the panel structure can be positioned on old houses or villas without altering the aesthetic appearance of the old houses or villas.    DETAILED DESCRIPTION - The pitched roof includes a covering of tiles, in which the covering is disposed on the base. The covering is provided to ensure watertightness and allow rainwater or the like to flow on top of the covering in a flow direction. The panel is positioned on the pitched roof. An INDEPENDENT CLAIM is also included for the interface component.    DESCRIPTION OF DRAWING(S) - The drawing is top view showing the details of the panel structure for roofs.
