High-efficiency array type focusing solar tracking system

Abstract

The present invention provide a high-efficiency array type focusing solar tracking system comprising a lens set, a solar cell platform, a track set, a driving device, a plate, and a second magnet set. With this system, a solar cell on the solar cell platform can be moved to a focus position of the sunlight passed through lenses of the lens set for collecting solar energy without moving heavy lenses, so as to reduce power consumption and to improve the power generation efficiency of the solar cell. Moreover, the sunlight that is not collected by the lenses yet can be collected by the plate with holes and optical fibers for other applications such as an illumination to improve the utilizing efficiency of the solar energy.
