Moreover, the features and benefits of the invention are illustrated by reference to the exemplified embodiments. Accordingly, the invention expressly should not be limited to such exemplary embodiments illustrating some possible non-limiting combination of features that may exist alone or in other combinations of features; the scope of the invention being defined by the claims appended hereto.

[0036] This disclosure describes the best mode or modes of practicing the invention as presently contemplated. This description is not intended to be understood in a limiting sense, but provides an example of the invention presented solely for illustrative purposes by reference to the accompanying drawings to advise one of ordinary skill in the art of the advantages and construction of the invention. In the various views of the drawings, like reference characters designate like or similar parts.

[0037] In an exemplary embodiment, a solar panel assembly is provided that has a frame with a built-in circuit board & battery. When light hits the solar panel, the internal battery charges. A user can then plug a USB compatible device (like a phone or tablet) into the frame and charge off-the-grid. The solar panel can be easily installed & used in any home, apartment, school, or other building.

[0038] FIG. 1 is a front perspective view of a solar assembly 100 in accordance with this disclosure. FIG. 2 is a back perspective view of the solar assembly 100 of FIG. 1. FIGS. 3 and 4 are front and back plan views respectively of the solar assembly 100. FIG. 5 is a top view of the solar assembly 100 and FIG. 6 is a bottom view of the solar assembly, and FIG. 7 is a section view of the solar assembly. It is noted that when referring to the “front” and “back” of the solar assembly 100, the front is the surface that faces the solar source of energy, such that when the solar assembly 100 is installed, the back side may be facing the inside of a room.

[0039] As shown, the solar assembly 100 typically comprises a frame 110, a transparent panel 120 mounted within the frame, with the frame forming a boundary about the transparent panel, and at least one solar cell 130 mounted on the transparent panel. The solar cell 130 is mounted such that a portion of the transparent panel 120 forms a boundary between the frame 110 and the solar cell. Accordingly, a transparent section is provided that fully surrounds the solar cell 130, providing the effect of the solar cell floating within the frame 110.

[0040] The solar cell 130 or cells may be provided as monocrystalline solar cells, polycrystalline solar cells, or bifacial solar cells. In some embodiments, the solar cell 130 may be one or more copper indium gallium selenide solar cell.

[0041] The solar assembly 100 typically provides a power storage element 140, such as a battery, and the power storage element may be located within a cavity 150 in the frame 110. The cavity may further contain a circuit board 160, typically in the form of a one or two sided printed circuit board (PCB), and other components required to operate the solar assembly 110. The solar assembly 100 also typically provides a power port 170 for accessing power stored in the power storage element 140. Such a power port may be a USB port, as shown. The circuit board 160 typically manages the charging of the power storage element 140, as well as the power output of any power at the power port 170.

[0042] The segment of the frame 110 containing the cavity 150 may be very thin, such that the frame can contain a cavity large enough to account for a traditional battery. Further, a custom PCB may be manufactured using low profile techniques in order to provide a board that can fit inside the cavity 150. Such a PCB may be, for example, USB mounted.

[0043] In some embodiments, the power storage element 140 may be removable or swappable. In some embodiments, the power storage element 140 may be a battery that is removable from the frame and usable on the go. Any standard battery type may be used, including, for example, lithium ion batteries.

[0044] A button 175 may be provided for controlling the solar assembly 100, or for turning it on and off, and one or more LEDs 177 may be provided for indicating status of the assembly 100. For example, the LEDs 177 may light up or flash a first pattern or color to indicate that a power storage element 140 is charging and a second pattern or color to indicate that the element is fully charged.

[0045] While the power port 170 is shown as a USB port, this is only one example of potential power ports. In some embodiments, the power port 170 may be a power cable for charging a user device. In such an embodiment, the solar assembly 100 may include a retracting mechanism for retracting the power cord into the frame 110 of the solar assembly 100. In other embodiments, a storage compartment may be included in the frame for storage of charging cables. In some embodiments, the power port 170 may be an AC outlet or a USB-C port.

[0046] A wire, shown, for example, in FIG. 12, is then provided for transporting power generated from the solar cell 130 to the power storage element 140.

[0047] In some embodiments, a single solar cell 130 is provided, and it may be mounted centrally within the frame 110 on the transparent panel 120. In other embodiments, several solar cells 130 may be provided, as shown, and they may form an aesthetically pleasing pattern, apparently suspended within the frame 110. In such embodiments, the pattern may comprise solar cells 130 immediately adjacent each other, or with some spacing between them, such that light passes through the assembly 100 in between the individual solar cells. Where multiple solar cells 130 are utilized, they may be arranged as a standard grid or in a decorative way, such as the herringbone pattern shown in FIGS. 8 and 9.

[0048] While some embodiments may provide a single transparent panel 120, such as that discussed above, typical embodiments provide a first transparent panel 120 and a second transparent panel 180 for sandwiching the solar cell 130, thereby protecting it from the elements. In such embodiments, the transparent panels 120, 180 may further protect the solar cell 130 and the wire. The wire may thereby be thinner, or uninsulated, so as to allow the wire to be invisible when viewed from outside the transparent panels 120, 180. The transparent panels 120, 180, are typically glass or plastic, but other transparent materials are contemplated as well.

[0049] In some embodiments, one or more of the transparent panels 120, 180 may further comprise a diffraction grating for diffracting light. In such embodiments, the diffraction grating may be part of the transparent panel 120, 180, or it may be an additional film to be applied to a surface. Such an embodiment is described in more detail below with respect to FIGS. 15 and 16.

[0050] As shown, the sandwich, formed from the transparent panels 120, 180 may incorporate resin in order to suspend the solar cells 130 between the panels. In such an embodiment, the first transparent panel 120 may be glass or plastic, and may be coated with a resin, and the second transparent panel 180 may be similarly coated with a resin, with the solar cells 130 suspended in between. Accordingly, there may be no space between the panels, and the resin may flow around the solar cells 130. Further, the resin may insulate the wire, such that no insulation is necessary.

[0051] In alternative embodiments, the solar cells may be located between glass sheets, in which case a space may be visible between the glass sheets in locations where no solar cells are present. This is shown, for example, in FIG. 17.

[0052] Further, while both materials are contemplated as transparent, in some embodiments, a second panel that is not transparent, or that is otherwise distinguished from the first panel, may be provided. For example, the second panel may comprise colored plastic or glass, or it may comprise metal, such as aluminum or stainless steel.

[0053] In some embodiments, the transparent panel 120, 180 covering the back of the assembly may further comprise a pocket for inserting an object to display, such as a photograph. Accordingly, when viewed from the back of the solar assembly 100, such as from inside a room in which the solar assembly is installed, the assembly may have the appearance of a picture frame. Alternatively, a pocket or cut out may be provided for supporting decorative inserts.

[0054] The frame 110 may comprise a wide variety of materials, including, for example, bamboo, wood, metal, or plastic. Such materials may be selected for insulative or aesthetic benefits.

[0055] A cable 190 may be provided for hanging the solar assembly 100. In some embodiments, one or more suction cups may be provided as well. Such suction cups may be provided for hanging the cable 190, or may be provided on the frame itself 110, allowing the frame to be directly mounted on a window. Other fixation assemblies for semi-permanently installing the solar assembly 100 may include a suction cup with a hook, transparent hook and loop material or 3M dual lock, micro suction tape, or semi-permanent transparent adhesives.

[0056] FIG. 8 is a front perspective view of a second embodiment of a solar assembly 800 in accordance with this disclosure. FIG. 9 is a front plan view of the solar assembly 800 of FIG. 8.

[0057] As shown, the solar assembly 800 includes a frame 810, a transparent panel 820, with the frame forming a boundary about the transparent panel, and a plurality of solar cells 830 forming a pattern, in this case, a herringbone pattern.

[0058] Other elements of the second embodiment of the solar assembly 800 are similar to those discussed above with respect to the embodiment of the solar assembly 100 shown in FIG. 1.

[0059] FIG. 10 is a front perspective view of a third embodiment of a solar assembly 1000 in accordance with this disclosure. As shown, the solar assembly 1000 may comprise a frame 1010, a transparent panel 1020, and a single solar cell 1030, mounted such that a portion of the transparent panel 1020 forms a boundary between the frame 1010 and the solar cell 1030.

[0060] FIG. 11 is a front perspective view of a fourth embodiment of a solar assembly 1100 in accordance with this disclosure. As shown, the frame 1110 may be configured to form a shape other than a rectangle, in this case a cat face, and the transparent panel 1120 may be provided for mounting the solar cells 1130 in a configuration that complements the overall shape of the frame 1110. Further, specialty solar cells 1140 may be provided at specified locations in order to enhance the aesthetic effect of the frame shape 1110 and to contrast with other solar cells 1130.

[0061] FIG. 12 is a front perspective view of a fifth embodiment of a solar assembly in accordance with this disclosure. As shown, the device may be provided with a bamboo finish, and the transparent panels may comprise plastic. Further, the wire may be visible between the transparent panels.

[0062] FIG. 13 is a front perspective view of a sixth embodiment of a solar assembly in accordance with this disclosure. As shown, the solar assembly 1300 may be incorporated into an appliance 1310, such as an air conditioner. In such an embodiment, the power storage element outputs power directly to the appliance 1310. Further, the solar assembly 1300 may provide a folding segment 1320 comprising solar cells 1330. The folding segment 1320 may be lowered when in use such that the solar cells 1330 may be better positioned to capture sunlight. When not in use, the folding segment 1320 may be raised so that the solar cells 1330 are located adjacent a window or are otherwise protected from the elements.

[0063] FIG. 14 is a front perspective view of a seventh embodiment of a solar assembly 1400 in accordance with this disclosure. As shown, the solar assembly 1400 is incorporated into an appliance, 1410, such as an air conditioner, and a frame 1420 is provided, the frame retaining the solar cells 1430.

[0064] FIG. 15 is a front view of components an eight embodiment of a solar assembly in accordance with this disclosure. As shown, a diffraction grating may be applied to a transparent panel used in the embodiment shown. Such a diffraction grating may generate a rainbow pattern as light passes through the assembly.

[0065] FIG. 16 is an image showing use of the eight embodiment of the solar assembly shown in FIG. 15. As shown, the diffraction grating on the transparent panel of the embodiment may generate a rainbow pattern in a room where the solar assembly is mounted in a window.

[0066] FIG. 17 is a section view of an embodiment in accordance with this disclosure. As shown, two transparent sheets sandwich solar cells. The transparent sheets are a stiff material, such as glass, such that where solar cells are not present, a gap 1700 exists between the sheets. This is in contrast with the section of the embodiment of FIG. 1, shown in FIG. 7, which includes a resin coating which effectively fills the gap between the sheets.

[0067] While the present invention has been described at some length and with some particularity with respect to the several described embodiments, it is not intended that it should be limited to any such particulars or embodiments or any particular embodiment, but it is to be construed with references to the appended claims so as to provide the broadest possible interpretation of such claims in view of the prior art and, therefore, to effectively encompass the intended scope of the invention. Furthermore, the foregoing describes the invention in terms of embodiments foreseen by the inventor for which an enabling description was available, notwithstanding that insubstantial modifications of the invention, not presently foreseen, may nonetheless represent equivalents thereto.
