PHOTOVOLTAIC PLANT

The invention relates to a photovoltaic plant (100) comprising: at least one photovoltaic module (1), including at least one junction box (13) placed on a front face of the photovoltaic module (1), via which face the solar rays enter, in proximity to a peripheral edge (4) of said photovoltaic module (1), and at least one DC current cable (15, 17) that conveys the current generated by the at least one photovoltaic module (1), characterised in that it furthermore comprises a protective sheath (5) that is placed, on the front face of the photovoltaic module (1), encircling the junction box (13) and the DC current cable (15, 17), said protective sheath (5) having a cross section the height of which corresponds at least to the height of the junction box (13) and including a window (57) that is located in the face of the protective sheath (5) that makes contact with the photovoltaic module (1), via which window the junction box (13) protrudes from the protective sheath (5), and a closable longitudinal aperture (51)
