Hatch, e.g. for an inland waterway cargo vessel, provided with photo-voltaic cells

An inland waterway cargo vessel having a cargo hold with an open top having a width and having a length defined by opposed longitudinal edges, wherein the vessel has a coaming along each longitudinal edge of the open top of the cargo hold, each coaming being provided with at least one horizontal rail,

• wherein the vessel is provided with a telescopically sliding hatch system having a set of hatches configured to slide horizontally over each other in a telescoping manner and in an operative position of each of the hatches covering the cargo hold, wherein a sliding hatch of the set of hatches is, at each of opposed sides of the sliding hatch, slidable over an associated horizontal rail provided on the coaming,
• wherein the vessel has an electrical grid comprising a consumer,
• wherein a surface area of at least one sliding hatch of the set of hatches is provided with photo-voltaic cells,
• wherein the at least one sliding hatch comprises, integrated with the at least one sliding hatch, a power converter system connected to the photo-voltaic cells and configured to be connected to the electrical grid of the vessel, and
• wherein the power converter system integrated with the at least one sliding hatch is configured to convert electrical energy generated by the photo-voltaic cells and entering the power converter system into an output form of electricity corresponding to the electrical grid of the vessel.
