NOVELTY - The flexible photovoltaic module comprises a base layer (11) that is mated with a photovoltaic film (13) by interposition of an intermediate junction element (12) made of polymeric material. The base layer is made of spread fabric that comprises a supporting fabric (14) covered with layers of plastics. A surface of the spread fabric is treated by lacquering. The intermediate junction element comprises a first sublayer (17) that is compatible with the lacquered surface, a second sublayer (18) that is compatible with the photovoltaic film, and a third layer (19).    USE - The flexible photovoltaic module is useful for making flat coverings such as tensioned structures, pressostatic shed structures, truck tarpaulins, sun shades and other similar coverings.    ADVANTAGE - The flexible photovoltaic module is easy to use, and can be simply, rapidly and economically manufactured with lightweight.    DETAILED DESCRIPTION - The flexible photovoltaic module comprises a base layer (11) that is mated with a photovoltaic film (13) by interposition of an intermediate junction element (12) made of polymeric material. The base layer is made of spread fabric that comprises a supporting fabric (14) covered with layers of plastics. A surface of the spread fabric is treated by lacquering. The intermediate junction element comprises a first sublayer (17) that is compatible with the lacquered surface, a second sublayer (18) that is compatible with the photovoltaic film, and a third layer (19) that is intermediate between the first sublayer and the second sublayer and is compatible with the first sublayer and the second sublayer. The supporting fabric is a high-tenacity polyester fabric, an acrylic fiber fabric, a glass fiber fabric, a mesh of metallic material or another similar and equivalent fabric. The layers of plastics are deposited with a method consisting of spreading, calendering or other similar and equivalent methods. The photovoltaic film is protected on the outside by a first protective outer layer (20) and by a second protective outer layer.
