[0031] With regards to the present invention, as illustrated in FIGS. 1 -9, a shading portion 12 of a device 10 may include any number of materials, designs, shapes and lengths that would serve to shade a window, sidewalk, outdoor recreational apparatus (for example, an outdoor spa or hot tub), or other such features and apparatus as would be contemplated by one of skill in the art, from sunlight and/or other environmental elements. Accordingly, a shading portion 12 may include a variety of shapes and sizes, including but not limited to rectangular, square, curved (dome or canopy, for example) or any combination thereof. A shading portion 12 may include a variety of materials, including but not limited to, plastic, metal, wood, glass, elastic or semi-elastic materials (such as nylon, polyester, canvas, etc) and any combination thereof. A shading portion 12 further may include any predetermined length selected to achieve a desired aesthetic and/or physical result. All of these features may be chosen on a custom basis. Most preferably, a shading portion 12 will easily house and support a photovoltaic portion 14, in its desired shape, size and material (as further described herein). Also, most preferably, a shading portion 12 is comprised of material that is weather-, water- and/or temperature-resistant or tolerant.

[0032] With regards to the present invention, as illustrated in FIGS. 1 -9, a photovoltaic portion housing 14a and photovoltaic portion 14 of a device 10 may include any number of materials and designs and sizes that would serve to provide sufficient energy to support the energy needs of a low-voltage device (as described herein), in a cost-effective manner. Any material capable of generating photovoltaic properties (as described herein)(for example, a solar panel) is contemplated for use in the present invention, provided that it is includes reliable functionality and is resistant and/or tolerant to environmental elements. The types of materials contemplated for use in housing and placement of the photovoltaic portion 14 at, near or within a shading portion 12 would include, but are not limited to, different types of metals (for example, aluminum), plastics, wood, glass, elastic and semi-elastic materials and fabrics, as well as any number of combinations thereof. Most preferably, the size and shape of the photovoltaic portion 14 provides the desired, reciprocal energy- producing and energy-support effects (for example, the "load" need of a power source 20, which is thereafter transferred to a particular low-voltage device, as effected by a particular geographic region; that is, availability and duration of sunlight exposure) to accommodate as many low-voltage devices as desired.

[0033] As shown in FIGS. 2 and 3, a load 22 (for example, a DC (Direct Current) and/or low-voltage device 22) contemplated for use in accordance with the present invention includes, but is not limited to, such devices as lights, ceiling fans (whether interior or exterior) and other similar apparatus. As shown in FIG. 3, wires 18 (such as DC wires) and/or lighter gauge wires (for example, wires which can be cut and spliced easily) may be used to direct power from a photovoltaic portion 14 to an energy storage portion 20 and accordingly, from an energy storage portion to a power control portion (not shown) to or from a load 22. The wires 18 described herein are connected therebetween using supporting devices and methods as would be contemplated by anyone of ordinary skill in the art. Also as shown in FIG. 3, an energy storage portion 20 is used to house the electrical energy collected as a result of the functionality of the photovoltaic portion 20, which will provide power for a load 22. Most preferably, an energy storage portion 20 is a rechargeable battery (or solar rechargeable battery), which includes a basic hard jamming circuit and self-regenerating system (for example, a deep cycle battery).

[0034] Examples of such batteries include but are not limited to motorcycle batteries (which are typically effective to 10 degrees below zero, and thus would be preferable for regions experiencing cold climates), forklift batteries, and car batteries, to name a few. Further, it is contemplated herein that batteries 20 may be strung together to obtain the desired load size (battery sizes are optional, as is voltage). Therefore, the load and voltage are both flexible and may be chosen to provide a desired effect. Most preferably, the battery 20 is kept on a charger (for example, a battery tender or a trickle charger). Such a device is preferable due to both its inherently minimal use of the electricity generated by the photovoltaic portion 14 and its ability to keep the battery for a duration of up to 5- 6 years or more (cost-effective). It is also preferable that a power control portion 30 (as shown and described in FIG. 10 below and herein) is used to regulate and direct energy. For example, a voltage regulator 30 may be used, which serves to smooth out the transition (for example, prevents or minimizes a stall or kill) when the electricity is generated by the photovoltaic portion 14. More specifically, the use of a voltage regulator is preferable either when electricity is not being drawn by a load 22 or when the sun is not out (for optimal collection of light by the photovoltaic portion 14). A voltage regulator typically regulates approximately 1 10 volts. [0035] FIG. 10 is a flowchart illustrating an electrical wiring and/or system of at least one embodiment of the present invention, as described herein. One of ordinary skill in the art would recognize the need to consult a regional, national or international electrical code, in conjunction with the following-described system. In at least one embodiment of the present invention, the electrical wiring and/or system may include connectivity between at least one photovoltaic portion 14, at least one energy storage portion 20 (for example, a battery, as earlier described), and at least one load portion 22 (for example, a ceiling fan, as earlier described), each of which are operably connected with at least one power control portion 30 (for example, a voltage regulator, as earlier described).

[0036] A power control portion 30 may perform several functions for the system of the present invention. For example, the power control portion 30 may prevent power leakage back through the photovoltaic portion 14 when they are in darkness and may thereby configured to adjust the loading of the photovoltaic portion 14 to maximize energy retrieved from the photovoltaic portions 14 (for example, photovoltaic "cells"). The power control portion 30 may further route power to and from an energy storage portion 20, so as to accommodate any requirements and limitations of the energy storage portion 20. For example, a chemical battery 20 can be charged by the incoming power but must be protected against, for example, overcharging or overheating. Supercapacitors or ultracapacitors 20 also may be used and are typically more tolerant of charging speeds, but have great variations in terminal voltage that must be accommodated. The power control portion 30 may also control the rate of voltage discharge and limits how low the discharged voltage can go to protect the energy storage portion 20 from damage.

[0037] In at least one embodiment of the present invention, the power control portion 30 may also regulate the output voltage as needed by various load portions 22, as well as limit the maximum and surge currents that a load portion 22 is likely to draw. The power control portion 30 may also give certain load portions 22, for example, emergency lights 22, higher priority than other load portions 22 operably connected with the system, when the available stored power is running low.

[0038] In at least one embodiment of the present invention, the electrical wiring/system may be configured for specific system voltage to accommodate system needs. For example, a system configured around the common automotive battery voltage (which ranges from approximately 1 1 V to 15 V) can use different load portions 22 designed for automotive and recreational vehicle uses. Commercially available converters can generate 120 V AC from a 12 V system for specific load portions 22 that use a higher voltage.

[0039] In at least one embodiment of the present invention, the device 10 may be installed by a commercial entity trained in installing the device 10 and in conformance with local, regional, national or international electrical code, as would be known by one of ordinary skill in the art. It is also contemplated herein that a device 10 may be installed by an individual if sold in kit form, in whole or in part, so long as the applicable electrical code (as earlier described) is implemented.

[0040] Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
