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

摘要

Object of the invention is a system composed of a special Tile, adequate to coverthe whole roof, thermally insulating, ventilated, with no environmental impact,producing solar and photovoltaic energy, adequate for the production of hotwater and/or electrical energy. The two funcions, 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 coveredsurfaces 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 positionedin the boiler, to complement hot water production during low irradiation seasons.The roof thus obtained is optimal in any climate; in areas subject to snowfallthe snow will melt on the tiles that anyway develop heat; in hot areas during thesummer very high temperatures will be achieved, thus it will be possible to transformwith heat exchangers the heat produced in cooling, obtaining air conditioningor cold water below the floor. Also, it will be possible to obtain heated waterfor pools from the excess of hot water both in the summer and in the winter.
