Abstract
Provided is a high-effective concentration photovoltaic solar tracking device and method; and, more particularly, to a concentration photovoltaic solar tracking device and method, which maximize concentration efficiency by concentrating solar light using a Fresnel lens and moving a solar panel based on focus information formed when the concentrated solar light is irradiated on a photodiode.
Claims15
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.

A concentration photovoltaic solar tracking method, comprising:
- primarily tracking solar light through at least two solar light detectors for detecting solar light by being formed on different axes of a solar panel for concentrating solar light;
- primarily controlling orbit and altitude of the solar panel based on a degree of brightness in the detected solar light;
- secondarily tracking solar light through a solar tracking sensor for concentrating the solar light irradiated to the solar panel by using a Fresnel lens and including a 4 division photodiode for detecting a focus of the Fresnel lens when the focus is irradiated;
- and
- secondarily controlling the orbit and the altitude of the solar panel based on focus information of the Fresnel lens formed on the detected 4 division photodiode.
