<P>PROBLEM TO BE SOLVED: To provide a thin light-weight circular sun light tracking device capable of obtaining significant augmentation of a power generation amount relative to a fixed-type sun light panel, always vertically tracking a trajectory of sun light in all the daytime over the year. <P>SOLUTION: A thin light-weight circular sun light tracking device is realized by dividing a circular sun light panel and glass thereon in parallel into plurality, and by always vertically tracking a sun light trajectory by electrically driving and controlling an azimuth and an elevation angle using revolution driving and oscillation driving simultaneously around two axes. The sun light tracking device can realize a maximum power generation amount, receiving more sun light. Since the whole device is configured thin and light-weight and, hence, influence of strong wind does not affect, installation sites thereof are expanded to roofs of general dwelling houses with slope as well as flat grounds, rooftops, or the like. Moreover, since the most significant feature is to drive the thin circular sun light panel, there is a merit in safety that problems do not arise even in a densely built-up area with many neighboring dwelling houses. <P>COPYRIGHT: (C)2012,JPO&INPIT |
