Claim Text:
1. A hybrid solar panel comprising: photovoltaic elements comprising a front face and a rear face, a heat exchanger positioned opposed to the rear face of the photovoltaic elements, a coolant fluid circulating in the exchanger cooling the photovoltaic elements, the heat exchanger comprising a heat transfer zone positioned under the photovoltaic elements and wherein the fluid flows, the transfer zone comprising elements disrupting the flow of the fluid so as to facilitate heat transfer in the transfer zone, wherein the transfer zone is formed by a lower exchange plate positioned under the photovoltaic elements and made of a heat conductive material, the lower exchange plate having an upper surface on which the coolant fluid flows with an array of integrated disruption elements extending over an entire thickness of a thin volume of the coolant fluid flowing in the transfer zone, the disruption elements being made of a same heat conductive material as the lower exchange plate, wherein the lower exchange plate is shaped to form channels for circulating fluid on opposite sides of the transfer zone, the channels having a depth greater than the thickness of the thin volume of coolant fluid flowing in the transfer zone so that the channels have pressure drops lower than a pressure drop in the transfer zone to provide uniform fluid distribution of the fluid in the transfer zone, and an upper exchange plate attached to the rear face of the photovoltaic elements, an upper end of the disruption elements being in surface contact with the upper exchange plate, a heat transfer being performed between the upper exchange plate and the lower exchange plate through the disruption elements, so that the coolant fluid collects heat from the photovoltaic elements not only at the rear face of the photovoltaic elements, but also at the lower exchange plate, making the temperature of the upper exchange plate homogenous without cold or hot spots, the upper end of the disruption elements being attached to the upper exchange plate, the disruption elements being distributed in discontinuous staggered rows extending along a length and width of the transfer zone and selected from the group consisting of nipples, semi-spheres, cylindrical tubes, polygonal tubes and pyramids.
