Abstract: A photovoltaic/thermal solar panel is presented which contains no glazing above the photovoltaic array. The absence of glazing allows the photovoltaic cells to operate at a lower temperature and therefore at a higher efficiency. In addition, the absence of glazing allows the present invention PV/T panel to be used to provide nighttime cooling for a building. The panel is constructed by adhering an aluminum heat transfer plate to the rear of the PV array in the panel using a silicone adhesive. PEX tubing is inserted into channels integrally formed into the back of the heat transfer plate again using silicone or other heat-conductive compound.
