## Abstract

A portable self-contained solar energy generation platform for tracking a source of solar energy and automatically maintaining optimum solar collection panel positioning for maximum energy output during operation. The solar tracking platform comprises a folding solar panel support stand on a power turntable with a solar tracker control actuation device in communication therewith.

## Claims

### Claim 1

A portable self-contained solar panel array comprising in combination,
a powered turntable having a ground engaging base and an oppositely disposed rotatable surface,
a base support frame secured to said rotatable surface of said powered turntable,
an electric motor on said rotatable surface interconnected to said base support frame,
a solar panel support frame hinge to said support frame,
a retainment frame hinged to said support frame in oppositely disposed relation to said solar panel support frame for selective engagement with said solar panel support frame,
said solar panel support frame and said retainment frame movable from a first folded flat position to a second upright engagement position with one another,
said solar support frame and said retainment frame are rectangular tubular construction of equal transverse dimension and unequal longitudinal length,
a hinged photovoltaic panel array including multiple solar cells removably secured to said solar panel main support frame,
an electronic solar tracker controller in electrical communication with said motor and said photovoltaic panel array.

### Claim 2 (depends on 1)

The portable self-contained solar panel array set forth in claim 1 wherein said tubular base further comprises, a ground engaging stationary base member, a bearing ring on said base member, said base rotatable surface secured to said bearing ring.

### Claim 3 (depends on 1)

The portable self-contained solar panel array set forth in claim 1 wherein said solar tracking controller comprises,
a housing,
a transparent dome on said housing,
an activation and solar positioning control circuit in electrical communication with said base member.

### Claim 4 (depends on 1)

The portable self-contained solar panel array set forth in claim 1 wherein said solar tracker controller is removably positioned to a portion of said hinged solar panel support frame and is programmed to analyze readings from a light sensor and control said electric motor to align said solar panel support frame and said solar panel thereon with the sun for maximum output.

### Claim 5 (depends on 1)

The portable self-contained solar panel array set forth in claim 1 wherein said electric motor further comprises,
interconnected gear reduction and a transfer drive shaft assembly registerable and in communication with said stationary ground engaging base.

### Claim 6 (depends on 1)

The portable self-contained solar panel array set forth in claim 1 wherein said solar tracker has an independent source of power.
