Sun tracker
Abstract
The basic idea of this invention is to use many small solar
energy transfer units like solar cells, each of them is of the same
size and installed on the surface of a spherical structure and
toward a certain direction in a 3-D space, the position of each
unit is saved in a database, by using a comparison unit to compare
the output of these solar energy transfer units, the optimized sun
direction can be determined; a compass maybe used to install the
said sun tracker in a fixed place.

Claims
1. what is claimed is a 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 location can be
determined.
2. said sun tracker comprising a basic spherical structure, said
basic spherical structure could be a spherical or a spherical based
polyhedron structure, optionally the polyhedron are a regular
polyhedron.
3. said sun tracker comprising polygon solar-energy transfer unit,
said polygon solar-energy transfer units are attached to said basic
spherical structure or the surface of said polyhedron structure;
optionally each of the said polygons are regular polygons; all of
said polygon solar-energy transfer units are of the same working
area, the same photo to electricity, photo to thermo or photo to
other kind of energy transfer efficiency; each of said polygon
solar-energy transfer units is fixed on said basic spherical
structure surface toward a certain direction, optionally each said
polygon solar-energy transfer unit is tangential to said basic
spherical structure surface at the attach point or attach surface
of said polygon solar-energy transfer unit to said basic spherical
structure.
4. said solar-energy transfer unit is able to transfer the solar
energy it received to certain output signals like electrical
voltage, electrical current, temperature, pressure, stress, strain
etc; said solar-energy transfer unit could be but not limited to
photovoltaic cell etc; optionally electrical resistances or other
elements are used to help obtain said output signals from said
solar energy transfer units; optionally a database could be built
to store the information such as number, relative location and
working direction of each solar energy transfer units; a compare
circuit is used to calculate out the one with the maximum output
and the one with the minimum output, optionally a small controller
with some or all of these functionalities are included, like
comparison functions, memory functions ets.

BACKGROUND OF THE INVENTION
[0005] 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.
BRIEF SUMMARY OF THE INVENTION
[0006] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0008] 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,
