Abstract:
1. A concentration photovoltaic solar tracking device, comprising: a solar panel for concentrating solar light; a solar tracking sensor, which is formed of a 4 division photodiode for concentrating the solar light irradiated to the solar panel by using a Fresnel lens, and detecting a focus when the focus of the Fresnel lens is irradiated; at least two solar light detectors, which are included on different sides of the solar panel and detect the solar light; and a control means, including: a first control unit for controlling the orbit and the altitude of the solar panel based on a degree of brightness in the solar light detected in the solar light detector, and a second control unit for controlling the orbit and the altitude of the solar panel based on focus information of the Fresnel lens, which is formed on the 4 division photodiode, wherein the solar tracking sensor includes: the Fresnel lens for concentrating solar light; a first print circuit substrate having the 4 division photodiode for detecting the focus when the concentrated solar light is irradiated and the focus of the Fresnel lens is formed; a solar light loss preventing means for supporting an interval between the Fresnel lens and the first print circuit substrate and preventing loss of the concentrated solar light; and a second print circuit substrate, which is connected to a lower part of the first print circuit substrate and has the second control unit receiving focus information of the Fresnel lens formed on the 4 division photodiode.
