Abstract: A system composed of a special Tile, to cover whole roof, thermally insulating, ventilated, with no environmental impact, producing solar and photovoltaic energy, adequate to make hot water and/or electrical energy. Two functions, thermal and photovoltaic, are designed to operate in synergy, or independently. The photovoltaic can help the thermal system, if covered surfaces are too small for heating needs of the building, or in non-ideal climates, sending part of electrical energy to electrical water heaters positioned in the boiler, to complement hot water production during low irradiation seasons. The resulting roof is optimal in any climate; in areas with snowfall snow will melt on tiles that anyway develop heat; in hot areas during summers very high temperatures occur, thus transforming heat in heat exchangers into cooling, obtaining air conditioning or cold water below the floor. It will be possible to obtain heated water for pools from excess of hot water in summer and in winter.

Abstract: Object of the invention is a system composed of a special Tile, adequate to cover the whole roof, thermally insulating, ventilated, with no environmental impact, producing solar and photovoltaic energy, adequate for the production of hot water and/or electrical energy. The two functions, thermal and photovoltaic, are meant to be operated in synergy, obtaining the best result, or independently. For instance, the photovoltaic can help the thermal system, in case the covered surfaces are too small for the heating needs of the building, or in non-ideal climates, sending part of the electrical energy to electrical water heaters positioned in the boiler, to complement hot water production during low irradiation seasons.
