NOVELTY - The photovoltaic tile (10A,10B) is overlapped to other equal or alike tiles in case of suitably interfaced on surfaces exposed to sun rays, such as roofs and roofings. The tile is essentially composed of a supporting portion for photovoltaic modules and composed of specific elements for electrical connection among adjacent tiles. The specific elements for electrical connection operate in conjunction with specific unit that make a stable mechanical constraint among tiles.    USE - Photovoltaic tile for entailing element for electrical connection to allow electrical continuity with other adjacent tiles.    ADVANTAGE - The elements for electrical connection among adjacent tiles are structured to concurrently make a stable mechanical constraint among tiles. The photovoltaic tile is enabled to be more simply and cheaply implemented. The photovoltaic tile is adapted to be laid and fastened directly on roof rafters and stably constrained to the other equal tiles. The continuity of the electrical connection is ensured. The tile allows to realize the best working conditions and to ensure an aesthetical appearance of the manufactured product of optimal level. The tile has holes that are intended for stably fastening the tile to the roof rafters. The stable mutual mechanical fastening of adjacent and overlapped tiles is provided. The pin element has an integral head that is composed of an insulating plastic cap provided with an O-ring to ensure a perfect tight against rainwater. The opening for inserting the pin into the upper tile has a diameter slightly greater than the diameter of the pin, to allow adjustments during the installation of tiles. The insulating material filling the cup is partially elastic to improve a possible adjustment of the pin position and thus of the mutual position of the installed tiles. The stable electrical and mechanical connections among adjacent tiles are achieved. The stable fastening of the same tiles one to another is obtained. The tiles are provided with photovoltaic modules adapted to operate with highest efficiency and without aesthetical impact. Hence cost is effectively reduced and installation is easily achieved.
