NOVELTY - The system has a light concentrating unit arranged to focus solar light to a convergence point that is located outside of and near a plane of a hole of a hollow spherical reflector (5), where the reflector is arranged to pass the light from the concentrating unit through the hole into an inner side of the reflector. An infrared filter (4) is arranged to cover the hole in which a focal point of an ellipsoidal reflector (2) coincides with a focal point of a parabolic reflector (1). Photovoltaic modules (6) are arranged inside the hollow spherical reflector for absorbing light.    USE - Solar energy concentrating system e.g. reflection-type concentrating system such as plane mirror reflection-type concentrating system and curved mirror reflection-type concentrating system, and transmission-type concentrating system such as Fresnel-type concentrating system and prism-type concentrating system, for use on roof of a house or a car to generate photovoltaic energy/power based on reflection.    ADVANTAGE - The infrared filter covers the hole in spherical reflector surface to reduce heat in the photovoltaic modules under concentrated light. The parabolic reflector and the ellipsoidal reflector obtain highly concentrated light, so that hollow spherical reflector ensures light uniformity on the photovoltaic modules, thus increasing light utilization and collection efficiency. The system uses a lens that homogenizes the light and keeps photovoltaic modules perpendicular to the light to reduce reflection loss. The lens is inexpensive. The system is surrounded by plane minor reflectors to increase light concentration. The system can concentrate the light on photovoltaic panels so as to improve conversion efficiency, thus decreasing use of solar cell materials to obtain electricity, and hence reducing cost of power generation by the photovoltaic panels. The light reflected by the photovoltaic modules is again reflected back onto the photovoltaic modules by inner surface of the hollow spherical reflectors, so that light collection efficiency can be maximized and efficiency of the system can be enhanced. The system can make use of even the smallest area of the photovoltaic modules to reach optimum efficiency and cost.
