AI Technical Summary

Benefits of technology

"The invention is a two-axis solar tracker that solves issues with traditional trackers. The design keeps the solar panel weight and lateral force away from the azimuth and elevation drives, reducing the force required to turn the panel. The solar panels are balanced on a horizontal beam, making it easy to rotate them. The elevation drive also demands very little force for rotation. The azimuth and elevation drivers can be easily installed and replaced, prolonging the life of the tracker. A wind lock device is also included to protect the linear actuators and solar tracker from wind abuse. Overall, the invention improves the efficiency and durability of solar trackers."

Problems solved by technology

If anything happen to the slewing drive, the entire solar panel has to be removed or dismantled.
This will greatly prolong the life span of linear actuator and the solar tracker from wind abuse.

Embodiment Construction

[0024]Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

Tracker Supporting Structure

[0025]As shown in FIG. 1, one aspect of the disclosed two-axes tracker generally designated as 10, includes a fixed cylindrical ground post 20, with a cylindrical rotating head 30 looped on top of the ground post 20. The rotating head 30 is made of a cylindrical tube with top end sealed (welded) by a top square plate 36, or other shape such a U-shaped pipe holder, etc. Preferred embodiment of the ground post 20 and rotating head 30 are made of rust-proof steel material which attract magnet. Inside the rotatin...

Abstract

The present invention relates to a simplified and lower cost two-axes tracker for solar PV (photovoltaic) or CPV (concentrated photovoltaic) solar panel, as well as heliostat solar reflectors and solar Stirling engine. In particular, the disclosure addresses a simplified and gravity centered tracker structure with low cost single or dual linear actuators mounted on the side of ground post which is easier for replacement and maintenance at lower cost.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based on and claims benefit of U.S. Provisional Application Ser. No. 61 / 274,927, filed on Aug. 24, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a simplified and lower cost two-axes tracker for solar PV (photovoltaic) or CPV (concentrated photovoltaic) solar panel, as well as heliostat solar reflectors and solar Stirling engine. In particular, the disclosure addresses a simplified and gravity centered tracker structure with low cost single or dual linear actuators mounted on the side of ground post which is easier for replacement and maintenance at lower cost.[0004]2. Description of the Prior Art[0005]Photovoltaic solar panels are gradually becoming a fixture on roof tops in residential street. The sun exposure to fix panel on the roof is proportional to sine of sun elevation angle to the panel. In other words, solar collection on horizontal flat panel at sunrise a...
