Benefits of technology

[0011]One aspect of the present invention is to provide an apparatus to track the sun by digital image comparison to achieve accurate alignment to the sun. In another aspect of the invention, the apparatus can predict the sun's position in the sky based on the stored historical data.
[0015]1. The alignment of the solar tracking apparatus with the sun can be very accurate, and the power generation has a full capacity.
[0018]4. The solar tracking apparatus can predict the sun's position with software to quickly follow the sun's move.

Problems solved by technology

Another problem is that the sensitivity of the apparatus 1 is limited.
When the region B is large, the alignment of the apparatus 1 to the sun is not very accurate.

Embodiment Construction

[0030]The technical features and advantages of the present invention will be illustrated as following, which will be understood and operated by anyone of the ordinary skill in the art. Also the objects and advantages may be best understood by referring to the disclosed context, claims, and drawings. The context of the present invention and the detailed description are described to help clarify the invention, and are not intended to limit the invention from that described in the claims.

[0031]Referring to FIG. 5, the solar power generation system 2 includes a supporter 22, a solar panel 24, a solar tracking apparatus 26, and a power driving apparatus 28. The supporter 22 is a pillar to support the whole system 2. The solar panel 24 converts light energy into electrical energy by the photovoltaic effect, and has a light collecting surface 24a, as the conventional solar panel. The solar panel 24 is disposed on the supporter 22 and can be rotated in various directions. In this embodiment...

Abstract

The present invention provides a solar tracking apparatus for use with a power driving apparatus. The solar tracking apparatus includes: a memory unit for recording a first solar image; an image capturing unit for capturing a second solar image; and an processing unit for obtaining difference between the first solar image and the second solar image; wherein the processing unit activates the power driving apparatus in response to the difference. Furthermore, the present invention also provides a solar power generation system using the solar tracking apparatus. Besides the solar tracking apparatus, the solar power generation system also includes a solar panel; the power driving apparatus for adjusting the position of the solar panel, wherein the processing unit of the solar tracking apparatus activates the power driving apparatus based on the difference so that the solar panel is aligned with the sun to gather the solar energy of the sun.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001]This application claims the right of priority based on Taiwan Patent Application No. 097114033 entitled “solar tracking apparatus and solar power electric generation system thereof”, filed on Apr. 17, 2008, which is incorporated herein by reference and assigned to the assignee herein.FIELD OF THE INVENTION [0002]This invention relates to a solar tracking apparatus and a solar power generation system thereof, and more particularly to a solar tracking apparatus to track the sun by digital image comparison.BACKGROUND OF THE INVENTION [0003]A conventional solar tracking apparatus adopts a light sensor to track the sun. The light sensor sends a sensing signal to a power driving apparatus when it senses the “obliquely” incident sun light. In response to the sensing signal, the power driving apparatus adjusts the solar tracking apparatus as well as solar cells aligned with the sun.[0004]Referring to FIGS. 1 and 2, a conventional solar tracking ...
