AUTOTRACKING SYSTEM OF THE RAYS OF THE SUN

摘要

The present invention relates to a system for automatically tracking solar-light of an apparatus for generating photovoltaic power using a photovoltaic panel capable of maximizing light collection efficiency by controlling that a photovoltaic panel is vertical to the direction of solar-light using an optical sensor. The system for automatically tracking solar-light comprises: a photovoltaic panel generating power by collecting incident light; a rotation supporting unit which supports the photovoltaic panel and rotates the photovoltaic panel about one point on a rear surface of the photovoltaic panel; and a sensor unit which is provided in the photovoltaic panel to measure the amount of incident light. The sensor unit includes a light receiving sensor installed on a rear surface side of the photovoltaic panel to sense the solar-light incident from the rear side of the photovoltaic panel. According to the present invention, the system for automatically tracking solar-light is not required to have an operation device in which a separate algorism is set and can control the photovoltaic panel to the original position regardless of the direction of the incident solar-light by controlling the position of the photovoltaic panel using the light receiving sensor, thereby maximizing generation efficiency by controlling the photovoltaic panel even if the solar-light is discontinuously radiated, for example, i) when the sun rises after sunset, ii) when the sun rises after the sunrise remaining unclear for a long time by rain.
