Abstract

A solar powered vehicle topper unit and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to an electronic display within a housing. The solar energy harvesting device is located above the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.

First claim

What is claimed is:

1. A solar powered vehicle topper unit (“VTU”) comprising:
an electronic display;
a housing for said electronic display; and
a solar energy harvesting device electrically connected to said electronic display, wherein said solar energy harvesting device has a first footprint and said housing has a second footprint which is smaller than said first footprint.

2. The solar powered VTU of claim 1 wherein:
said solar energy harvesting device is located above said housing such that said first footprint overlies said second footprint.

3. The solar powered VTU of claim 2 further comprising:
a support structure extending between said housing and said solar energy harvesting device.

4. The solar powered VTU of claim 3 wherein:
said support structure extends between said housing and said solar energy harvesting device to elevate said solar energy harvesting device above said housing such that a bottom surface of said solar energy harvesting device is spaced apart from a top surface of said housing.

5. The solar powered VTU of claim 1 further comprising:
an energy storage device electrically connected, directly or indirectly, to said electronic display and said solar energy harvesting device.

6. The solar powered VTU of claim 5 wherein:
said energy storage device comprises a vehicle battery.

7. The solar powered VTU of claim 6 wherein:
said vehicle comprises an electric propulsion system comprising said vehicle battery.

8. The solar powered VTU of claim 6 wherein:
said vehicle comprises an internal combustion engine and an alternator electrically connected, directly or indirectly, to said vehicle battery.

9. The solar powered VTU of claim 1 further comprising:
a mounting device for mounting said housing to a roof of the vehicle.

10. The solar powered VTU of claim 9 wherein:
said mounting device comprises a first crossbar and a second crossbar.

11. The solar powered VTU of claim 1 wherein:
said solar energy harvesting device has a maximum width dimension that is larger than a maximum width dimension of said housing.

12. The solar powered VTU of claim 1 wherein:
said solar energy harvesting device has a maximum length dimension which is larger than a maximum length dimension of said housing.

13. The solar powered VTU of claim 1 wherein:
said solar energy harvesting device has a maximum width dimension that is larger than a maximum width dimension of said housing; and
said solar energy harvesting device has a maximum length dimension which is larger than a maximum length dimension of said housing.

14. The solar powered VTU of claim 1 further comprising:
an open loop airflow pathway for ambient air extending through at least a portion of said housing.

15. The solar powered VTU of claim 14 further comprising:
one or more fans located within said housing and configured to move said ambient air through said open loop airflow pathway when operated.

16. The solar powered VTU of claim 1 further comprising:
a closed loop airflow pathway for circulating gas extending within said housing; and
one or more fans located within said housing and configured to move said circulating gas through said closed loop airflow pathway when operated.

17. A method for providing solar power to a vehicle topper unit (“VTU”), said method comprising:
securing a solar panel above a housing for a first electronic display and a second electronic display, where said solar panel is electrically connected to said first electronic display and said second electronic display;
securing said housing, directly or indirectly, to a roof of a vehicle;
operating said vehicle on one or more roadways; and
passing electrical current from said solar panel to said electronic display while operating said vehicle on said one or more roadways;
wherein said solar panel has a first footprint which is larger than, and overlies, a second footprint of said housing.

18. The method of claim 17 wherein:
a bottom surface of said solar panel is spaced apart from an upper surface of said housing; and
a structure extends between said solar panel and said housing to secure said solar panel in an elevated position above said housing.

19. The method of claim 17 further comprising:
electrically connecting, directly or indirectly, one or more fans located within an open loop airflow pathway extending through at least a portion of said housing to said solar panel; and
operating each of said one or more fans, at least in part, with electrical current supplied by said solar panel to move ambient air through said open loop airflow pathway.

20. A system for providing solar power to a vehicle topper unit (“VTU”), said system comprising:
a first crossbar secured to a roof of a vehicle at a first location;
a second crossbar secured to the roof of the vehicle at a second location spaced apart from the first location;
a housing having an upper surface, wherein a proximal portion of said housing is secured to said first crossbar and a distal portion of said housing is secured to said second crossbar;
a first electronic display located within said housing to face a first direction;
a second electronic display located within said housing to face a second direction;
a cooling system located at least partially within said housing and configured to remove heat generated by the first electronic display and the second electronic display when operated;
a solar energy harvesting device located above said housing and comprising a substrate and a plurality of photovoltaic cells arranged on said substrate, wherein said solar energy harvesting device is electrically connected, directly or indirectly, to said first electronic display, said second electronic display, and said cooling system for supplying electrical power to said first electronic display, said second electronic display, and said cooling system at least some of a time said first electronic display, said second electronic display, and said cooling system are operated; and
a battery for said vehicle electrically connected to said first electronic display, said second electronic display, and said cooling system, where said battery is configured to supply power to said first electronic display, said second electronic display, and said cooling system at least some of the time said first electronic display, said second electronic display, and said cooling system are operated;
wherein said solar energy harvesting device has a footprint which is larger than a footprint of said housing.
