Solar roof tile with solar and photovoltaic production of hot water and electrical energy

A system for covering roof and wall structures of buildings and producing thermal and photovoltaic energy, comprising a first plurality of covering tiles, wherein each covering tile comprises:

• an upper element comprising a convex portion having an inner surface treated so as to be reflecting, the upper element being coated with one or more first photovoltaic elements,
• a base, provided with a reflecting plate covering a thermally insulating element, having a concave portion in correspondence with the convex portion of the upper element,
• said convex portion of the upper element and said concave portion of the reflecting plate forming a cavity wherein a greenhouse effect is produced when the tile is exposed to solar radiation,
• a radiation absorbing main pipe being positioned within the cavity in correspondence with a center of the convex portion of the upper element, the base being provided with lower positioning stands, so as to be capable to be supported by the stands over a structure and to form an air and ventilation chamber, wherein corresponding pipes of adjacent tiles are connected to each other and to a heat exchanger or insulated boiler heating coils for the production of hot water, or steam, wherein the photovoltaic elements of the tiles are connected together and to an accumulator or electrical distribution system, wherein the tiles are supported by the respective lower positioning stands over a structure so as to form the air and ventilation chamber wherein the reflecting plate comprises a flat portion outside the cavity wherein one or more second photovoltaic elements are positioned in corresponding housing, and wherein a corresponding portion of the upper element is made of transparent glass or plastic polycarbonate or plastic.
