Concentrating solar cell demonstration board

The utility model relates to a concentrating solar cell demonstration board. The concentrating solar cell demonstration board comprises a panel, Fresnel lenses, solar cell panels, a pedestal plate and connecting posts. The panel is a regular polygon, and multiple Fresnel lenses are evenly inlaid on the surface of the panel. The pedestal plate is provided with the solar cell panels of which the number is the same with that of the Fresnel lenses, and the solar cell panels are arranged within the focal length of the effective radiation area of the Fresnel lenses. The lower part of the panel is provided with a pair of positive and negative connecting posts, a DC voltmeter and a DC ammeter. The beneficial effects of the concentrating solar cell demonstration board are that luminous energy transition efficiency of solar energy can be enhanced by using the Fresnel lenses for concentrating so that power generation capacity at low illumination level is guaranteed; three solar cell panels are connected in series and six sets are connected in parallel, output voltage is about 3V and working current is 1000mA; and use area of the solar cell panels is saved under the same illumination condition, and the outputted electric energy of the same size of the solar cell panels under the device is enhanced for more than 85%.
