Photovoltaic and thermal solar panel

The invention relates to a hybrid solar panel comprising: a photovoltaic module; a heat exchanger arranged opposite the rear surface of said photovoltaic module; a cooling fluid circulating in said exchanger; the heat exchanger including a heat exchange area; inner channels extending over the entire surface of the exchange area; the heat exchange area is made up of a double cellular plate with cells provided in the form of adjacent inner channels in fluid communication with the intake and discharge areas, characterised in that: the side ends are sealed; the plate comprises openings made in the lower wall in order to establish fluid communication between each channel and the intake and discharge areas, respectively; and the intake and discharge areas are provided in the form of collectors placed on the lower wall at the openings, so that said upper wall remains planar over the entire surface thereof.
