Description

Attorney Docket No.: 968 / 7 PCTMULTIFUNCTIONAL SOLAR POWER DECK SYSTEMTECHNICAL FIELD

[0001] The presently disclosed subject matter generally relates to a solar power deck system. More specifically, the present invention relates to a solar power deck system that includes photovoltaic cells embedded in deck or patio building materials. A cooling fluid, such as water, is used to cool the solar cells; and, heat transferred to the water may be used for additional purposes.CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 687,054, filed on August 26, 2024, which is incorporated in its entirety herein by reference.BACKGROUND

[0003] Solar power has long been regarded as an important renewable energy alternative to traditional fossil-fuel energy sources. Substantial resources have been directed toward improving technologies for harnessing solar energy in residential, commercial, and industrial settings, where significant amounts of power may be generated to supplement or replace conventional energy supply. A well-known method of solar energy harvesting involves the use of solar modules assembled into arrays, which capture and convert incident sunlight into usable energy.Attorney Docket No.: 968 / 7 PCT

[0004] Solar modules may employ a variety of technologies and materials to generate power from sunlight. For example, photovoltaic (PV) systems commonly include solar panels fabricated from crystalline silicon, thin films, perovskite materials, or III-V semiconductor compounds such as gallium arsenide (GaAs). These modules convert solar radiation into direct current (DC) electricity, which is typically routed by wiring through electrical components such as switches, inverters, junction boxes, or charge controllers in order to condition the power for storage or end-use applications.

[0005] Although PV systems are widely deployed, most conventional installations mount solar modules on rooftops or other exposed, elevated, or otherwise inaccessible locations. Such placements present a number of disadvantages. For instance, maintenance, inspection, or manual operation of rooftop modules may require a technician to access precarious areas, increasing safety risks due to falls, electrical hazards, or inclement weather. Additionally, the elevated placement of modules can complicate repairs, add installation expense, and limit integration with existing structural aesthetics. In many cases, operational modifications, such as shutting down a PV module or adjusting its performance parameters, require physical interaction with hardware positioned in these difficult-to-reach locations. Such limitations detract from the flexibility, safety, and efficiency of current solar power systems.

[0006] Accordingly, there exists a need for improved solar energy collection systems that address these shortcomings by offering safer, more accessible, and more easily integrated alternatives. In particular, it would be advantageous to provide a solar system capable of unobtrusive incorporation into existing infrastructure, that allows ready access for inspection and control, and that can leverage both electrical and thermal energy for enhanced efficiency. The present disclosure addresses these needs by providing a solar deck system, a green technologyAttorney Docket No.: 968 / 7 PCT solution configured for off-grid or grid-connected applications, that integrates solar power generation directly into deck structures, thereby improving accessibility, safety, controllability, and functional versatility.SUMMARY

[0007] This summary is provided to introduce in a simplified form concepts that are further described in the following detailed descriptions. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it to be construed as limiting the scope of the claimed subject matter.

[0008] Disclosed herein, in one or more embodiments, is a solar power deck or patio system configured for integration into residential, commercial, or industrial environments. The system provides a dual-function energy platform comprising electrical energy generation from solar cells and thermal energy management through integrated cooling arrays, thereby enhancing overall system efficiency, reliability, and longevity.

[0009] In various embodiments, the deck system comprises a plurality of planks, preferably constructed from natural or engineered wood materials (e.g., pine, Douglas fir, or laminated wood), arranged to form a deck, patio, or comparable platform structure. Each plank may define a recess or chamber formed in a support step configuration, the recess being configured to receive at least one solar cell. A transparent covering may be disposed above the solar cell such that the covering is substantially flush with the superior walking surface of the plank to protect the solar cell from environmental exposure while preserving plank durability and walkability.Attorney Docket No.: 968 / 7 PCT

[0010] The solar cells of the solar planks are operably and electrically interconnected to form a circuit, the circuit being routed toward a central location or corridor of the deck structure. Electrical energy generated by the solar cells is directed to at least one power storage unit, which may include, without limitation, a battery, capacitor, flywheel, or functional equivalent thereof. The electrical energy stored may be further distributed for powering residential or commercial loads or for supplying operating power to auxiliary system components.

[0011] To address thermal inefficiencies inherent to photovoltaic operation, the planks may further include a cooling array disposed within the recess beneath the solar cells. In one embodiment, the cooling array comprises a plurality of cooling tubes, preferably formed of copper or another thermally conductive material, embedded within an aluminum heat sink to facilitate efficient thermal transfer. The cooling array is operably connected in a circuit between opposing fluid storage tanks such that a cooling medium, e.g., water or another fluid, may be circulated through the tubing. In operation, the cooling fluid absorbs heat conducted from the solar cells and plank structure, thereby reducing operating temperature. The heated fluid is then collected and stored in an insulated tank, sand battery, or equivalent thermal storage medium.

[0012] In certain embodiments, the thermal energy recovered in the heated fluid may be repurposed for secondary applications. For example, the heated fluid stored in the insulated tank or sand battery may be directed to at least one heat pump operably integrated with the system. In this arrangement, the pre-warmed fluid elevates the inlet temperature to the heat pump, thereby improving heat pump efficiency and reducing reliance on auxiliary electrical heating elements. Concurrently, electrical energy stored in the power storage unit may be used to energize the heat pump and associated circulation pumps, thereby enabling the solar deck system to operate in a substantially self-sustaining, off-grid configuration.Attorney Docket No.: 968 / 7 PCTBRIEF DESCRIPTION OF THE DRAWINGS

[0050] Disclosed herein, in one or more embodiments, is a solar power deck and / or patio system 10 incorporating an integrated cooling system 52 configured to maximize energy efficiency and system longevity. The deck system 10 comprises a plurality of planks 12 constructed from lumber, including solid wood or laminated wood materials. The planks 12 may be formed of natural wood, such as pine or Douglas fir, or any other suitable wood type or engineered equivalent. In certain embodiments, the planks 12 conform to standardized deck plank dimensions, such as eight-foot long 2x6 planks, although other suitable lengths, widths, or geometries may be employed. A first set of planks 12 may comprise solar planks incorporating one or more solar cells 24, while a second set of planks 12 may comprise blank planks without solar cells, the blank planks being usable as trim members or non-solar decking sections. By constructing solar planks 12 in standardized deck sizes, existing decks or patios may be repaired, renovated, or retrofitted to incorporate solar planks of the present system without requiring complete reconstruction of the underlying structure.Attorney Docket No.: 968 / 7 PCT

[0051] In one or more embodiments, a plurality of the planks 12 are arranged with substantially uniform spacing to collectively define a patio, deck, or other walkable surface. A portion of the superior surface 14 of at least one plank 12 may be routed, carved, or otherwise formed with a recess 30 or chamber (terms used interchangeably herein) configured to receive at least one solar cell 24. In some embodiments, laminated planks 12 may be constructed in a support-step 28 design configured to define such a recess 30 or chamber to house the solar cell 24 and other components associated with the solar plank 12.

[0052] Each solar deck plank 12 may comprise: (i) a superior surface 14, also referred to herein as an “upper” surface or “walking surface”; (ii) an inferior surface 16 , also referred to as an “underside”; (iii) an interior 16 surface upon which one or more solar cells 24 and / or cooling tubes 46 are disposed; (iv) opposing longitudinal side surfaces 20; and (v) opposing terminal ends 22. The solar plank design enables incorporation of solar cells 24 directly into deck planks 12, thereby establishing a usable, walkable solar energy field integrated into a deck installation, as opposed to conventional installations requiring rooftop or ground-mounted solar panels. In certain embodiments, the number of solar planks 12 within the deck structure may be varied, allowing implementations in which every deck plank 12 incorporates at least one solar cell 24, or hybrid implementations comprising both solar planks and blank planks to achieve a combination of solar energy generation and desired aesthetic or decorative effect.

[0053] According to one or more embodiments, the solar deck system 10 may be configured with one or more sensors 26 operable to collect operational and environmental data associated with the system 10. Such sensors 26 may include, without limitation, temperature sensors, moisture sensors, humidity sensors, vibration sensors, light sensors, time-of-day or position sensors, and other suitable types of sensing devices. The sensors 26 may provide dataAttorney Docket No.: 968 / 7 PCT via wired or wireless connections, including through circuit boards, quick-connect wiring, or other suitable electrical interfaces.

[0054] In certain embodiments, data provided by the sensors 26 may be communicated to a computer system, microcontroller, or other processing unit for analysis, monitoring, and / or control. Communications may be provided via a wireless transceiver, direct wired connection, or any suitable communication protocol. Sensor data may optionally be stored locally in non-volatile memory or remotely in a cloud-based storage system for subsequent retrieval and analysis. As will be appreciated by those of skill in the art, a “computer system” or “data processing system” as referenced herein may include one or more processors (e.g., central processing units, digital signal processors, microcontrollers, or application-specific integrated circuits), together with one or more computer-readable storage media storing instructions executable by the processor(s). For example, one or more programs, applications, or modules may be embodied as instructions on a tangible, non-transitory computer-readable medium, which, when executed by the processor(s), cause the computer system to perform one or more operations such as receiving sensor data, analyzing said data, generating control signals, or transmitting information to external devices.

[0055] In some embodiments, firmware, hardware logic, and / or software modules may be employed individually or in combination to cause a system of one or more computers to perform specific functions associated with operation of the solar deck system. Accordingly, references herein to actions or operations performed “by a computer system” encompass actions executed by such processors under instruction from computer programs, hardware logic, firmware modules, or any suitable combination thereof.Attorney Docket No.: 968 / 7 PCT

[0056] Regarding assembly and construction of each solar plank 12, FIG. 1A shows three separate pieces of lumber 13 sawed and ready to be affixed together to form a wood laminate plank 12. Laminated wood is preferable as it provides increased strength and durability over a single piece of wood. Laminated wood planks also allow for scrap wood or salvaged wood to be repurposed into environmentally friendly deck planks. To create a laminated wooden plank 12, multiple sections of wood 13 are adhered or glued together to form a single plank 12, as shown in FIG. IB. The laminated planks 12 are made up of at least three layers which are formed by turning the natural fibers of the wood in different directions and then joining them together. Laminated wood is more flexible than most types of wood, thereby making it more resistant to natural disasters such as earthquakes or wind. Other advantages of laminated wood include higher thermal insulation, thereby saving energy; and laminated wood is lighter than other building materials, thereby making the power deck system 10 easier to transport and construct.

[0057] FIG. IB also shows the support step design 28 of the solar plank 12 that allows for the support and placement of the different elements and features of the power deck system 10. The separate wood pieces 13 of a wood laminate plank 12 may be cut such that they create the support step design 28 when affixed together, as shown in FIG. 1A. Alternatively, each solar plank 12 may be routed in the center or cut to have the support step design 28 after the lamination process. This support step design 28 creates a chamber or recess 30 in the plank 12 whereby the solar cells 24 and cooling tubing 46 can be embedded in the routed, recessed section 30 and covered with a thick transparent covering 38, as shown in FIGs. 2-4. This support step design 28 also allows the plank 12 to be load bearing capable of supporting people, deck furniture, etc.Attorney Docket No.: 968 / 7 PCT

[0058] In one or more embodiments, the interior of the support step chamber 30 may be lined with a reflective material 32, such as aluminum foil or foil tape, configured to direct incident light rays onto the surface of the solar cell 24 and thereby increase solar conversion efficiency. The reflective material 32 may be adhered to the interior sidewalls of the chamber 30 to maintain low visual impact and unobtrusive appearance.

[0059] Further, one or more wedges 34 may be installed within the chamber 30, each wedge 34 being configured to support and position the solar cell 24 at a predetermined tilt angle. The tilt angle may be selected or adjusted based on the latitude, orientation, or other site-specific parameters, so as to optimize incident solar radiation received by the solar cell 24. For example, as shown in FIG. 6, a wedge 34 may be disposed beneath the solar cell 24 and transparent covering 38 to elevate one end of the cell 24, thereby angling the solar cell 24 toward the sun’s position in the sky. This adjustable mounting allows the solar cell 24 to be positioned at the optimal angle for maximum solar gain, while the deck plank 12 upper surface 14 remains substantially flat and walkable, thus enabling integration of tilted solar cells 24 within a planar deck surface.

[0060] In one or more embodiments, an anti-splitting plate 36 may be affixed (using liquid rubber, threaded fasteners, or the like) to the terminal ends 22 of each plank 12 to prevent splitting and warping of the wood and to increase the durability and longevity of the deck planks 12. FIGs. 15A through 15C are various views illustrating an anti-splitting plate 36 affixed to a terminal end 22 of a solar plank 12.

[0061] In one or more embodiments, a transparent covering 38 is disposed over the solar cell 24, such that the transparent covering 38 is flush with the superior surface 14 of the plankAttorney Docket No.: 968 / 7 PCT12. The transparent covering 38 protects the solar cell 24 from the elements and provides strength, durability, and walkability to the planks 12.

[0062] FIG. 2 illustrates the transparent covering 38 seated within the first step of the recess 30, while FIG. 3 illustrates a solar cell 24 seated below the transparent covering 38, within the second step of the recess 30. The transparent covering 38 may be constructed of industrialgrade glass, preferably class one and bullet rated, to withstand walking and damage from the elements. If constructed of glass, the transparent covering 38 may also comprise a film or adhesive covering on its surface to protect from shattering in the event that the glass cracks or breaks. Other durable transparent materials may also be used to cover the solar cells 24 provided the material is strong enough to withstand walking, running, outdoor elements, and weather fluctuations. The solar cell 24 and transparent covering 38 may be affixed to the plank 12 preferably using a watertight, flexible adhesive such as silicone adhesive to accommodate shrinkage and expansion of the wood, although any suitable affixing means such as adhesive, fasteners, or the like may be used.

[0063] Additionally or alternatively, the plank 12 itself can include anti-slip 40 materials. FIG. 3 illustrates two embodiments of anti-slip 40 manufacturing that can be embedded into the plank 12, such as a groove, channel, or geometric cutouts cut along a length of the plank 12 and filled with an abrasive material or materials, such as stone, grit, and the like. The transparent covering 38 may also comprise an anti-slip 40 manufacture to make the surface as slip resistant as possible and within relevant building codes.

[0064] FIG. 5 illustrate a solar plank 12 at various stages of construction. FIG. 5 is a perspective view of an embodiment of a finished plank 12 with only a transparent covering 38Attorney Docket No.: 968 / 7 PCT(left) and an embodiment of a finished plank 12 with a solar panel 24 underneath the transparent covering 38 (right).

[0065] In one or more embodiments, each solar plank 12 may include one or more solar cells 24 disposed within a step-down 28 chamber 30 of the plank 12 structure. A plurality of solar planks 12 may be operably interconnected by way of electrical communication means 41, including but not limited to, waterproof electrical couplings, quick-connect wiring , or functionally equivalent electrical interconnections, thereby facilitating modular assembly and reliable electrical communication between adjacent solar planks 12.

[0066] Each solar plank 12 may further include an access panel 42 disposed on or within the plank 12 structure, the access panel 42 providing entry to electrical wiring 41 and connection points. The electrical wiring 41 of each solar plank 12 may be operably coupled to wiring 41 of one or more adjacent planks 12 and / or to at least one energy storage device 44 such as a battery. In various embodiments, the solar plank system 10 is configured to direct electrical energy generated by the integrated solar cells 24 to the energy storage device 44 for accumulation and subsequent retrieval. Electrical energy stored in at least one battery 44 may be utilized to power one or more loads, including but not limited to residential loads, commercial loads, or any other suitable application, thereby enabling integration of the solar plank system 10 into a wide variety of environments.

[0067] In one or more embodiments, an opening is cut through the inferior surface 16 at or near each terminal end 22 of the deck plank 12 to provide at least one access panel 42 on the inferior surface 16, or underside, of the planks 12 to allow for the wiring connections 41 of the solar cells 24 and interconnection points for the cooling tubing 46. FIGs. 12B and 12C best illustrate the access panel 42 openings. The terminal ends 22 of the cooling tubing 46 and theAttorney Docket No.: 968 / 7 PCT wiring connections 41 for the solar cells 24 may enter and exit through the access panel 42 for operable interconnection with adjacent deck planks 12 or other components of the system 10 as needed. The solar cell wiring 41 and cooling tubing 46 of one solar deck plank 12 may be operably interconnected with the solar cell wiring 41 and cooling tubing 46 of an adjacent solar deck plank 12 either end-to-end (like a train), such as in FIG. 12D, or side-by-side, such as in FIGs. 12B and 12C, depending on the construction, sizing, and layout of the entire deck system 10.

[0068] FIG. 12A through 12C are a side view and underside views of a plurality of planks 12 illustrating an embodiment of the interconnection of solar plank wiring 41 and cooling tubing 46 in a side-by-side connection configuration. FIG. 12B and 12C specifically are underside views of three planks 12 illustrating the interconnection of cooling tubing 46 with elbow fittings 48 and the exit point (access panel 42) for the solar panel wiring connections 41. The cooling tubing 46 exits the access panels 42 at a terminal end 22 of each plank 12 and are interconnected via elbow fitting 48 to the cooling tube 46 of an adjacent plank 12.

[0069] In a preferred embodiment, the terminal ends 22 of each deck plank 12 are capped off or covered by an end cap 50. The end cap 50 may be constructed of the same material used to construct the deck plank 12, such as wood, or any other suitable material. FIGs. 7A and 7B illustrate preferred embodiments of the end cap 50 prior to full insertion or placement at the terminal end 22 of the plank 12. FIG. 8 illustrates a series of deck planks 12 side by side with solar cells 24 installed in each and end caps 50 capping off the terminal ends 22 of each plank 12. FIG. 9 also illustrates positioning of the cooling tubing 46, the solar cells 24, the transparent covering 38, and fasteners 64 used to affix the terminal caps 50 to each opposing terminal end 22 of the deck planks 12.Attorney Docket No.: 968 / 7 PCT

[0070] In a preferred embodiment, the solar deck system 10 includes a cooling array 52 to increase solar cell efficiency and longevity while providing another energy source from waste heat, described further herein. The cooling array 52 (as shown best in FIGs. 4C, 11, 12B 13A-C) preferably comprises a plurality of operably interconnected cooling tubes 46 disposed along an interior surface 18 of a solar plank 12 and extending longitudinally across the plank 12, generally beneath one or more solar cells 24. The cooling array 52 is configured to dissipate excess heat generated during operation of the solar cells 24, thereby cooling the deck system 10 and preventing overheating of the photovoltaic modules.

[0071] In one or more embodiments, the cooling array 52 is operably coupled to at least one fluid pump 54 configured to circulate a cooling medium 53, such as water or another fluid, through the tubes 46 of the array 52. The cooling tubing 46 may be formed from copper or another thermally conductive material. The cooling medium or fluid 53 circulated through the tubing 46 absorbs unproductive heat from the solar array, thereby transferring the absorbed thermal energy to downstream holding tanks where it may be captured and stored. In this manner, the cooling array not only enhances solar cell efficiency and longevity but also provides an additional source of recoverable thermal energy otherwise dissipated as waste heat.

[0072] The fluid pump 54 may deliver the cooling medium 53 from a first holding tank 56 into the cooling array 52, where the medium 53 absorbs thermal energy, and thereafter direct the heated fluid into at least one second holding tank 58 for storage. The holding tanks 56, 58 may be insulated such that thermal energy collected in the heated fluid can be retained for subsequent recovery or use.

[0073] In practice, only approximately twenty percent (20%) of solar radiation absorbed by photovoltaic cells is converted into electric current, with the remaining approximately eightyAttorney Docket No.: 968 / 7 PCT percent (80%) being converted into thermal energy. Elevated operating temperatures are known to adversely affect solar cell efficiency, as energy conversion output decreases by approximately 0.3 to 0.5 percent for each degree Celsius above about twenty-five degrees Celsius (approximately seventy-seven degrees Fahrenheit). Accordingly, the cooling array 52 provides a thermal management system configured to maintain maximum solar cell efficiency at elevated ambient or operating temperatures, thereby improving both power output and service life of the photovoltaic deck system 10.

[0074] FIG. 4A illustrates a lateral cross-sectional view of a solar plank 12 according to one or more embodiments. As shown, a plurality of cooling tubes 46 extend longitudinally across a recess 30 of the plank 12, positioned beneath the solar cell 24 and covered by the transparent protective layer 38 disposed above the solar cell 24. The cooling tubes 46 may be operably interconnected with corresponding cooling tubes 46 of adjacent planks 12 through the use of elbow fittings 48, or other suitable joining components, thereby forming a continuous cooling circuit across multiple planks 12.

[0075] In one or more embodiments, the cooling tubing 46 of the solar deck system 10 may be disposed in thermal communication with an aluminum heat sink 60 integrated into the plank 12 structure. The aluminum heat sink 60 may comprise one or more channels, grooves, or recesses 61 configured to securely receive and support the cooling tubing 46 therein. Aluminum is a particularly advantageous material for use in this context due to its high thermal conductivity, corrosion resistance, and structural durability. By embedding the cooling tubing 46 within an aluminum heat sink 60, thermal energy generated by the solar cells 24 and adjacent materials is more efficiently conducted away from the plank 12 surface and transferred to the circulating cooling fluid 53. This improves heat dissipation, reduces operating temperatures ofAttorney Docket No.: 968 / 7 PCT the solar cells 24, and thereby enhances photovoltaic conversion efficiency and device longevity. Furthermore, the aluminum heat sink 60 provides mechanical support and protection for the cooling tubes 46 against physical stress, load, or environmental exposure, while simultaneously optimizing thermal transfer characteristics to maximize the dual benefits of electrical generation and waste-heat recovery.

[0076] FIG. 4B illustrates lateral cross-section of an embodiment of a solar plank 12 whereby the cooling tubes 46 are disposed or embedded within an aluminum heatsink 60. FIG.4C illustrates that the cooling tubes 46 within the aluminum heat sink 60 may be arranged in an alternating, winding, or serpentine pattern comprised of multiple rows, such that thermal coverage is distributed across a greater portion of the plank 12 surface area.

[0077] FIG. 11 illustrates a top cross-sectional view of two solar planks 12, wherein cooling tubes 46 disposed within each of the respective planks 12 are interconnected to extend fluid communication from one plank 12 to the next. In certain embodiments, the cooling tubes 46 within a given plank 12 may be arranged in an alternating, winding, or serpentine pattern comprised of multiple rows, such that thermal coverage is distributed across a greater portion of the plank 12 surface area. By way of illustration, FIG. 11 depicts two rows of cooling tubing 46 disposed within a single plank 12, while FIG. 4A depicts six rows of cooling tubing 46. It will be understood, however, that any suitable number of rows may be incorporated into a plank 12 depending on design requirements, desired cooling capacity, or specific application conditions. Accordingly, the number, geometry, and arrangement of cooling tubes 46 within a given plank 12 may be varied as needed without departing from the scope of the present disclosure.

[0078] In one or more embodiments, the cooling array 52 is arranged in an alternating, circuitous, or serpentine pattern configured to facilitate sustained circulation of a coolingAttorney Docket No.: 968 / 7 PCT medium 53 that may be stored within a plurality of fluid storage tanks 56, 58 and pumped through the cooling array 52 by means of at least one fluid pump 54 operably coupled to the array 52.

[0079] Each cooling array 52 may comprise a first-end and a second-end, with interconnected cooling tubes 46 extending longitudinally between the opposing ends. The terminal end of a cooling tube 46 at the first-end of the cooling array may be fluidly and operably connected to at least one first fluid storage tank 56, while the terminal end of the cooling tube at the second-end of the cooling array 52 may be fluidly and operably connected to at least one second fluid storage tank 58. The tubing 46 at the first-end and second-end is arranged such that the cooling medium 53 pumped from the first tank 56 may flow freely throughout the array 52 and be collected into the second tank 58, and likewise, fluid 53 from the second tank 58 may be circulated in the reverse direction toward the first tank 56.

[0080] In operation, the cooling medium 53 or fluid may be pumped from a storage tank 56, 58 associated with the first-end of the cooling array 52, flow through the cooling tubing 46 of the cooling array 52, and absorb thermal energy from the solar planks 12 as it circulates. The heated fluid is then collected and stored in the tank 58 at the second-end. As the fluid stored in the second tank 58 cools to an acceptable temperature, it may be drawn from the second-end, recirculated through the array 52, and collected in the tank 56 at the first-end. This bidirectional exchange establishes a continuous cooling cycle that may operate for as long as needed or desired to maintain stable operating temperatures. Further, in certain embodiments, a deck or patio system 10 of substantial size may incorporate multiple cooling arrays 52, each fluidly connected to corresponding pairs of storage tanks, such that sufficient quantities of cooled fluidAttorney Docket No.: 968 / 7 PCT can be delivered and cycled through the overall solar deck system 10 to maintain effective cooling and operational performance.

[0081] In one or more embodiments, a plurality of solar planks 12 are configured such that the solar cells 24 integrated therein are electrically interconnected in a circuit arrangement. The circuit may be routed to a central location or central corridor of the deck, whereby electrical energy generated by the solar cells is collectively directed to at least one energy storage device 44, such as a battery or other suitable storage unit. Similarly, the cooling tubes 46 disposed within the solar planks 12 may be fluidly interconnected such that heated fluid circulated through the individual cooling arrays 52 is collected at a central location and delivered into one or more insulated storage tanks 56, 58.

[0082] The thermal energy contained within the warmed or heated fluid collected from the cooling arrays 52 may be advantageously repurposed for additional applications. In certain embodiments, at least one heat pump 62 is operably connected to the solar deck system 10 such that the warmed fluid stored in the insulated tank(s) 56, 58 is directed to the heat pump 62 to enhance thermal efficiency. Conventional heat pumps exhibit reduced performance at lower ambient temperatures and often require supplemental electric resistance coils to pre-condition or preheat intake air, thereby decreasing overall efficiency. By contrast, in the solar deck system 10 of the present disclosure, the warmed fluid collected via the cooling arrays 52 is utilized to condition or elevate the heat pump’s 62 operating temperature, thereby improving efficiency and reducing reliance on auxiliary electric heating. In addition, the electrical energy stored in the energy storage device(s) 44 as generated by the solar cells 24 may be used to provide operating power to the heat pump 62. In this manner, the solar deck system 10 provides a self-sustaining, off-grid or partially off-grid arrangement suitable for both residential and commercialAttorney Docket No.: 968 / 7 PCT applications, supplying both thermal and electrical energy derived from integrated solar plank assemblies.

[0083] The cooling array 52 may include smart sensors 26, such as temperature sensors, configured to monitor the temperature throughout the deck system. These sensors 26 may be affixed on the planks 12 or embedded within the recess 30 of the solar planks 12 and may be operably connected to a computer processor configured to perform particular operations or actions. The temperature sensors 26 may communicate information to the deck system 10 such as turning the cooling array on / off, adjusting the flow rate of the cooling fluid 53 (a faster flow if the temperature is increasing, for example), and duration of cooling. The sensors 26 may also detect if temperatures are approaching freezing, thereby communicating to the system to activate a frost plug to drain the water from the cooling array 52 to avoid freezing within the tubes 46.

[0084] Regarding assembly of the solar deck as a system 10, a simplified and improved method of construction is provided. In one or more embodiments, the planks 12 are fastened together to construct a deck using hidden fasteners 64 as shown in FIG. 10. Conventional hidden deck fasteners 10 are comprised of multi -piece clips and screws that must be separately affixed to the joists and planks of the deck and interlocked together. The fastener of FIG. 10 is a hip fastener-type that secures the wood in two locations, rather than one, for additional strength and durability. The fastener 64 resembles a steel screw with double steel discs 66 having a predetermined spacing that may be maintained and reinforced with nuts 68. The double discs 66 are designed to fit into corresponding double grooves 70 of the deck planks 12. FIG. 9 illustrates a lateral cross-section of an embodiment of the solar plank 12 illustrating the fastener grooves 70 on opposing longitudinal exterior sides 20 of the terminal ends 22 of the plank 12. TheAttorney Docket No.: 968 / 7 PCT placement of the grooves 70 and corresponding fasteners 64 may be at any desired and suitable location along the longitudinal exterior sides 20 of the planks 12.

[0085] In one or more embodiments, as the solar planks 12 are secured in place to form a deck structure, the solar cell wiring 41 and cooling tubing 46 disposed within each plank 12 are routed through access panels 42 located on the underside of the planks 12. These access panels 42 are configured to stage the wiring 41 and tubing 46 for operable interconnection with corresponding wiring 41 and tubing 46 of adjacent planks 12 and with other components of the deck system 10. Once a plurality of solar planks 12 are fully assembled and fastened into the deck structure, the solar cell wiring 41 and cooling tubing 46 may be accessed from beneath the deck for operable connection and system integration.

[0086] The solar cells 24 of adjacent planks 12 may be electrically interconnected using waterproof electrical couplings, quick-connect wiring, or other suitable interconnection technologies. As discussed herein with regard to certain embodiments, the wiring 41 may be routed through access panels 42 disposed at the underside 16 or terminal ends 22 of each plank 12, thereby enabling concealed yet serviceable connection. Similarly, as illustrated in FIGS. 12B and 12C, the cooling tubing 46 of adjacent planks 12 may be fluidly interconnected and operably coupled by elbow fittings 48, quick connectors, or any equivalent means of fluid interconnection. The planks may be interconnected in either an end-to-end arrangement, as illustrated in FIG. 12D, or in a side-by-side arrangement, as illustrated in FIGS. 12B and 12C, depending upon the desired deck design and system configuration. In certain embodiments, a sealing material such as silicone may be applied to the access panels after completion of wiring connections to provide a substantially watertight seal.Attorney Docket No.: 968 / 7 PCT

[0087] As further shown in FIG. 12D, the end-to-end plank interconnection permits the solar planks 12 to be configured in a “train” orientation, thereby accommodating decks of varying lengths or dimensions. For example, when each solar plank 12 has a nominal length of approximately eight feet and a deck of thirty feet by thirty feet is desired, the final plank 12 of the end-to-end train may be trimmed to approximately six feet in length while still maintaining functional operability of both the cooling tubing 46 and solar cell wiring 41 for return to the central deck system 10. Accordingly, the modular interconnectivity of the planks 12 allows for customization of deck dimensions while preserving the electrical and fluid connectivity of the solar deck system 10.

[0088] As illustrated in FIG. 13 A, the electrical wiring connections 41 of the solar cells 24 may be operably connected to at least one energy storage device 44, such as a battery, for accumulation and storage of electrical energy generated by the solar cells 24. FIG. 13B provides a simplified schematic view of an embodiment in which a plurality of solar planks 12 are operably connected to both at least one battery 44 and at least one fluid storage tank 56, 58, thereby collectively enabling storage of both electrical and thermal energy. The solar deck system 10 may be assembled with flexibility to accommodate a variety of installation configurations. Specifically, because the electrical wiring connections 41 of the solar cells 24 and the cooling tube 46 connections of the planks 12 are accessed from beneath the deck structure, operable connection to the energy storage device(s) 44 and to the fluid storage tank(s) 56, 58 may be routed or convened at any suitable location depending upon the orientation, size, or placement of the deck installation. For example, such components may be positioned directly beneath the deck or alternatively disposed to one or more sides of the deck, as may be most convenient for installation, accessibility, or serviceability.Attorney Docket No.: 968 / 7 PCT

[0089] FIG. 13C illustrates a schematic diagram of an embodiment of an off-grid, closed-loop solar deck system 10. In the embodiment shown, the system 10 comprises a plurality of solar deck planks 12 operably coupled to an insulated heat exchanger 72. The insulated heat exchanger 72 is configured to receive a warmed working fluid from cooling tubing 46 disposed in or proximate to the power deck planks 12, to route the warmed fluid through one or more heat transfer coils 71 for extraction of thermal energy, and to thereby cool the fluid prior to recirculation to the deck system 10.

[0090] Thermal energy removed from the warmed fluid within the heat exchanger 72 may be diverted to a heat pump 62, the heat pump 62 being operable to provide selective heating and / or cooling to an associated environment. Electrical energy generated by the solar deck system 10 is stored in an energy storage unit 44, the energy storage unit 44 comprising one or more of a battery, a sand-based thermal battery, a flywheel, a capacitor, or a functional equivalent thereof.

[0091] When a sand battery 44 is implemented, thermal energy from the warmed fluid of the power deck is transferred to the sand battery 44 via a closed-loop transfer system. The sand battery 44 may comprise a quantity of sand contained within an insulated enclosure or disposed within a subterranean pit, such sand mass being thermally elevated through receipt of heat energy from the warmed fluid. A collection conduit 74 coupled to the heat pump 62 may withdraw stored thermal energy from the sand battery 44 for input into the heat pump 62, thereby increasing operational efficiency of the heat pump 62.

[0092] Electrical energy produced by the deck system 10 is further configured to power auxiliary system components including, but not limited to, the heat pump 62 and one or more fluid circulation pumps 54. Operation and coordination of said system components may beAttorney Docket No.: 968 / 7 PCT effected through a control system 76 implementing smart technology. The surface of the deck system 10 remains clean and free of any wires, tubes, fasteners, etc. FIG. 14 is a perspective view illustrating a person walking across an embodiment of the power deck, illustrating a clean and simple assembly.

[0093] In addition to solar cells 24 and cooling arrays 52, additional features may be incorporated into the deck system 10. For example, the deck system 10 of the present invention may comprise an adjustable light source 78 and intelligent lighting mechanisms incorporated therein. The deck planks 12 may incorporate a light 78 and / or lighting mechanism thereby creating a combined solar lighting deck plank, and the solar cell 24 may supply power to the light source 78. The light source 78 may be a smart lighting system that can be controlled wirelessly via a smart device, thereby providing remote control of the light on / off, intensity of the light, and lighting patterns. A circuit board and wiring harness may be mounted within the chamber 30 of the deck plank 12, and the light source 78 may be powered by a central battery 44 operably connected to the solar deck planks 12 or another source of power. The lighting 78 may be programmed to operate similarly to an automatic street light. For example, a light-dependent resistor or sensor can differentiate day and night, powering the light on automatically as the sun goes down. The circuit thus saves electrical power as well as manpower.

[0094] The light source 78 can be used for various purposes such as to direct pedestrians, to indicate directional pathways, or to provide accent lighting. The lights78 may be programmed to flash or remain solid, and different colors of light may be incorporated. For example, the light source 78 can flash or transition to different colors for practical or decorative purposes. For example, it is contemplated that the light source 78 could change color with the rhythm of music for entertainment purposes. Furthermore, standard lighting may be used for accent lighting,Attorney Docket No.: 968 / 7 PCT garden lighting, or the like. The solar lighting planks 12 may also illuminate a pathway for easy visibility. Lighting patterns, colors, and intensities may be programmed by a computer or smart device.

[0095] Particular embodiments and features have been described with reference to the drawings. It is to be understood that these descriptions are not limited to any single embodiment or any particular set of features, and that similar embodiments and features may arise or modifications and additions may be made without departing from the scope of these descriptions and the spirit of the appended claims.

In general, the terms used in the following claims should not be construed to limit the disclosure to the specific embodiments disclosed in the specification, unless the above Detailed Description section explicitly defines such terms. Accordingly, the actual scope of the disclosure encompasses not only the disclosed embodiments, but also all equivalent ways of practicing or implementing the disclosure under the claims.
