A photovoltaic module having: - a transparent first layer forming the front side of the photovoltaic module, which is intended to receive a light flux, - a plurality of photovoltaic cells placed side-by-side and electrically connected to one another, - an encapsulating assembly able to encapsulate the plurality of photovoltaic cells, and having a lower portion and an upper portion, the encapsulating assembly preferably being made of polymer, - a second layer having at least one polymer resin- and fibre-based composite material, the encapsulating assembly and the plurality of photovoltaic cells being located between the first and second layers, at least the first layer and the second layer defining the edges (1A, 1B, 1C, 1D) of the photovoltaic module; characterised in that the plurality of photovoltaic cells is spaced apart by a non-zero distance D A from at least one edge of the photovoltaic module, and in that the photovoltaic module further comprises a third layer, or strengthening layer, located below the plurality of photovoltaic cells and above the lower portion of the encapsulating assembly, said third layer forming at least one peripheral strip extending from the at least one edge toward the centre of said module and the width (L 15A) of which is larger than or equal to the distance D A, said third layer comprising at least one polymer resin- and fibre-based composite material. - a transparent first layer forming the front side of the photovoltaic module, which is intended to receive a light flux, - a plurality of photovoltaic cells placed side-by-side and electrically connected to one another, - an encapsulating assembly able to encapsulate the plurality of photovoltaic cells, and having a lower portion and an upper portion, the encapsulating assembly preferably being made of polymer, - a second layer having at least one polymer resin- and fibre-based composite material, the encapsulating assembly and the plurality of photovoltaic cells being located between the first and second layers, at least the first layer and the second layer defining the edges (1A, 1B, 1C, 1D) of the photovoltaic module; characterised in that the plurality of photovoltaic cells is spaced apart by a non-zero distance D A from at least one edge of the photovoltaic module, and in that the photovoltaic module further comprises a third layer, or strengthening layer, located below the plurality of photovoltaic cells and above the lower portion of the encapsulating assembly, said third layer forming at least one peripheral strip extending from the at least one edge toward the centre of said module and the width (L 15A) of which is larger than or equal to the distance D A, said third layer comprising at least one polymer resin- and fibre-based composite material. the encapsulating assembly and the plurality of photovoltaic cells being located between the first and second layers, at least the first layer and the second layer defining the edges (1A, 1B, 1C, 1D) of the photovoltaic module; characterised in that the plurality of photovoltaic cells is spaced apart by a non-zero distance D A from at least one edge of the photovoltaic module, and in that the photovoltaic module further comprises a third layer, or strengthening layer, located below the plurality of photovoltaic cells and above the lower portion of the encapsulating assembly, said third layer forming at least one peripheral strip extending from the at least one edge toward the centre of said module and the width (L 15A) of which is larger than or equal to the distance D A, said third layer comprising at least one polymer resin- and fibre-based composite material.
