Hybrid solar panel comprising: - photovoltaic elements comprising a front face and a rear face, - a heat exchanger positioned facing the rear face of the said photovoltaic elements, - a coolant circulating through the said exchanger so as to cool the said photovoltaic elements, - the said exchanger comprising a heat exchange zone arranged under the said photovoltaic elements and in which the said fluid flows, the said exchange zone is formed by a bottom plate having perturbation elements perturbing the flow of the said fluid so as to encourage exchanges of heat in the exchange zone, - the said inbuilt perturbation elements extending over the entire thickness of the layer of coolant flowing in the said exchange zone, characterized in that - the bottom plate is a heat exchange plate made of a heat conducting material and shaped in such a way as to form the perturbation elements right from the time of manufacture of the said plate, which elements are produced from the same material as the said plate, - the upper end of the perturbation elements is in surface contact with the rear face of the photovoltaic elements, the surface contact between the upper end of the perturbation elements and the rear face of the photovoltaic elements ensures transmission of heat to the bottom plate so that the coolant captures the heat emanating from the photovoltaic elements not only on the rear face of the said photovoltaic elements but also on the bottom plate so that the said photovoltaic elements are chiefly cooled at these points of contact, - the perturbation elements form bosses on the top face of the plate over which the coolant flows and form recesses on the underside face of the said plate which is not in contact with the said fluid and which is the opposite face to the said top face. - photovoltaic elements comprising a front face and a rear face, - a heat exchanger positioned facing the rear face of the said photovoltaic elements, - a coolant circulating through the said exchanger so as to cool the said photovoltaic elements, - the said exchanger comprising a heat exchange zone arranged under the said photovoltaic elements and in which the said fluid flows, the said exchange zone is formed by a bottom plate having perturbation elements perturbing the flow of the said fluid so as to encourage exchanges of heat in the exchange zone, - the said inbuilt perturbation elements extending over the entire thickness of the layer of coolant flowing in the said exchange zone, - the bottom plate is a heat exchange plate made of a heat conducting material and shaped in such a way as to form the perturbation elements right from the time of manufacture of the said plate, which elements are produced from the same material as the said plate, - the upper end of the perturbation elements is in surface contact with the rear face of the photovoltaic elements, the surface contact between the upper end of the perturbation elements and the rear face of the photovoltaic elements ensures transmission of heat to the bottom plate so that the coolant captures the heat emanating from the photovoltaic elements not only on the rear face of the said photovoltaic elements but also on the bottom plate so that the said photovoltaic elements are chiefly cooled at these points of contact, - the perturbation elements form bosses on the top face of the plate over which the coolant flows and form recesses on the underside face of the said plate which is not in contact with the said fluid and which is the opposite face to the said top face.
