1. A solar-powered device comprising:

a. a mobile base unit comprising:

i. a trailer including a frame and wheels; and

ii. a housing attached to the trailer and formed of two opposing side walls that each are formed to include a recessed portion, the side walls being interconnected with a front wall and a back wall, and a roof attached to the side walls, the front walls, and the back wall to define an interior of the housing;

b. solar power modules that convert solar energy into electrical current, the solar power modules being separately attached directly to each of the two opposing side walls of the housing with a pivotal engagement at or near a top portion of the solar power module and at or near a top portion of the side wall and configured to pivot between a down position wherein an entire back surface of each of the solar power modules is received into the recessed portion of the housing side walls and an up position wherein the solar power modules are pivoted away from the recessed portion of the side walls;

c. a battery enclosed within the interior of the housing, the battery being at least partially rechargeable using the electrical current from the solar power modules; and

d. a lighting module associated with the mobile base unit that is at least partially powered either directly or indirectly using the electrical current from the solar power module.

2. The solar-powered device of claim 1 , wherein the back surface of each of the solar power modules comprises a back plate.

3. The solar-powered device of claim 1 , further comprising a control box comprising one or more components that control the solar power modules, the lighting module, or the solar power modules and the lighting module.

4. The solar-powered device of claim 1 , further comprising a mast that is attached to the lighting module and the mobile base unit.

5. The solar-powered device of claim 4 , wherein the mast is one or more of extendable, pivotable, and rotatable.

6. The solar-powered device of claim 4 , wherein the mast is pivotable and wherein the device further comprises a winching component for moving the mast between a down position and an up position.

7. The solar-powered device of claim 4 , wherein the mast is extendable and wherein the device further comprises a winching component for moving the mast between an unextended position and an extended position.

8. The solar-powered device of claim 1 , further comprising actuators connected to the housing of the mobile base unit and to the solar power modules.

9. The solar-powered device of claim 1 , wherein the lighting module is selected from the group consisting of light emitting diodes, electrodeless induction floodlights, gas discharge lamps, and combinations thereof.

10. The solar-powered device of claim 1 , further comprising a secondary battery charging component separate from the solar power modules.

11. The solar-powered device of claim 1 , comprising two or more independent off-grid solar-powered electric systems that each comprises a solar power module, a battery, and a lighting module.

12. The solar-powered device of claim 1 , wherein the lighting module provides illumination per the Illuminating Engineering Society of North America RP-20-98 standards of a minimum horizontal illuminance of at least about 0.2 foot candles (FC), a uniformity ratio (maximum to minimum illuminance) of 20:1, and a minimum vertical illuminance of at least about 0.1 FC.

13. A method of utilizing a mobile solar-powered lighting device, the method comprising:

a. configuring a mobile solar-powered lighting device in a transport mode wherein the mobile solar-powered lighting device comprises a mobile base unit comprising a trailer and a housing including opposing side walls formed to include recessed portions and also comprises two solar power modules that are independently attached to the opposing side walls with a pivotal engagement at or near a top portion of each of the solar power modules and at or near a top portion of each of the side walls, and wherein the configuring in a transport mode comprises pivoting the solar power modules to a down position wherein an entire back surface of each of the solar power modules is received into the recessed portion of the housing side walls;

b. transporting the mobile solar-powered lighting device;

c. configuring the mobile solar-powered lighting device in a charge mode where the solar power modules are pivoted away from the side walls;

d. charging a battery that is enclosed within the housing the solar power modules attached to the housing of the mobile solar-powered lighting device;

e. configuring the mobile solar-powered lighting device in a lighting mode; and

f. lighting an area.

14. The method of claim 13 , wherein configuring the mobile solar-powered lighting device in a transport mode includes placing a mast in a down position.

15. The method of claim 13 , wherein transporting includes towing the mobile solar-powered lighting device with a vehicle.

16. The method of claim 13 , wherein configuring the mobile solar light tower in the charge mode includes pivoting the two solar power modules into a position to optimize receipt of sunlight.

17. The method of claim 13 , wherein configuring the mobile solar-powered lighting device in the lighting mode includes raising a mast into a substantially upright position.

18. The solar-powered device of claim 10 , wherein the secondary battery charging component comprises an alternating current or direct current charging device.

19. The solar-powered device of claim 10 , wherein the secondary battery charging component comprises a wind mill.
