A flexible photovoltaic panel comprising: a plurality of photovoltaic cells (2); at least one encapsulating layer (3) of thermoplastic material adapted to contain therein the photovoltaic cells (2), this encapsulating layer being formed by first and second layers (3a, 3b) arranged on opposite sides of the photovoltaic cells and melted around the cells; at least one front layer (4, 5) of flexible plastic material joined to and superimposed on the encapsulating layer on a first surface thereof, this front layer being exposed to sunlight during use, and being at least partly made of ultraviolet-resistant material; and at least one back layer (6) of flexible plastic material joined to and superimposed on the encapsulating layer on a second surface, opposite to the first surface. The encapsulating layer (3) is made of thermoplastic olefin having a low water vapour transmission rate. The front layer has a thickness in the range from 100 to 600 micrometres, and at least one part thereof, in contact with the first surface of the encapsulating layer, is made of polyethylene terephthalate. The back layer is at least partly made of polyethylene terephthalate and has a thickness in the range from 100 micrometres to 600 micrometres. |
