This patent filing claims the benefit of earlier filed provisional applications: Application No. 60/861,212, filing date Nov. 27, 2006, Conformation No. 3829, filing receipt *OC000000021502638*, Title, Sun tracker.
Solar energy becomes more and more efficient, with its low pollution and the unlimited renewable energy resources; it has a bright future for the future. In order to make good use of the solar energy, a simple and high precise sun tracker is necessary. Most of the existing sun tracker is either less precise or more complicated; the invention of this sun tracker is to propose another kind of simple sun tracker with high precision.
This invention is a device which is able to tell the direction of the sun, it is simple and also could be of high precision; by using this device, the positions of some the solar energy devices driven by hydraulic systems or a electromechanical systems could be modified to work toward the sun direction, this way, the utilization of the sun energy can be increased to a higher level.
Solar energy has a broad application as a main source of low pollution and renewable energy resources. sun-tracker which is able to determine the optimal direction for a solar energy device to work toward, some solar energy transfer unit is fixed on a basic spherical structure and each of them towards a certain direction, the direction of all said solar energy transfer units around said basic spherical structure represent almost all the directions in a 3-D space, except a small surface area will be used to fix the sun tracker; If sun tracker is fixed, then the working direction of each solar energy transfer unit is certain and by comparing the output from each solar energy transfer unit, the optimal direction for other solar energy devices located at the same area can be determined; said sun tracker comprising,
