Description

A SOLAR INNOVATION SYSTEM

TECHNICAL FIELD

[0001 ] The present invention relates to shades and car ports for vehicles, particularly electric vehicles. In particular, the present invention concerns vehicle shades and car ports capable of harvesting and supplying electrical energy to electric vehicles.

BACKGROUND

[0002] Electric vehicles are becoming increasingly popular resulting in an increased demand on recharge locations. Currently, electric vehicle owners have the options of recharging their vehicle at designated commercial recharge locations or at their home, with the latter typically being via mains electrical supply, although renewable energy options do exist.

[0003] A problem in general with renewable energy options is that most domestic solar energy systems are not configured to store electrical energy generated. Instead, such systems normally feed generated electrical energy directly into the grid. Accordingly, such systems usually do not have the ability to directly charge an electric vehicle, particular at night during non-sunlight hours.

[0004] For domestic solar energy systems with direct energy storage facilities there is typically a labour cost involved in altering the systems for in-garage electric vehicle supply. However, with recent incidences of battery explosion, it not necessarily desirable to re-charge an electric vehicle in the closed confines of a home garage.

[0005] Solar car port system solutions do exist. However, such systems have typically been designed for commercial operation and are simply re-deployed in a residential environment with little regard to their aesthetic appearance and function in a residential setting. Apart from being usually bulky, permanently fixed and garish in appearance, they typically are provided at high cost and present many drawbacks, such as, e.g., difficulty in maintaining and/or cleaning.

[0006] For example, one such drawback is that houses and car ports often have nearby trees and neighbours. Overtime, this can result in the photovoltaic cells of a solar energy system or car port becoming covered with dust, leaves, lawn/garden clippings and/or other debris, which adversely affects energy production. Further, it can be difficult and dangerous for occupants to regularly gain access and clean the photovoltaic cells as required, and expensive if routinely hiring a cleaning specialist. SUMMARY OF INVENTION

[0007] Embodiments of the present invention provide a solar shade, a solar shade system and a solar car port, which may at least partially address one or more of the problems or deficiencies mentioned above or which may provide the public with a useful or commercial choice.

[0008] According to a first aspect of the present invention, there is provided a solar shade for a vehicle including: a shade frame movably coupled to a vertical support structure and having a plurality of photovoltaic cells mounted thereon, said shade frame being moveable relative to the vertical support structure between an operable position in which the shade frame provides shade and the photovoltaic cells are exposed to sunlight and a stowage position in which the shade frame is folded against the vertical support structure; and an actuating mechanism for moving the shade frame between the operable and stowage positions.

[0009] According to a second aspect of the present invention, there is provided a solar shade for a vehicle including: at least one vertical member having a lower end, an opposed upper end and an elongate body extending therebetween, said lower end being mountable to a support surface for supporting said vertical member in an erect position; a shade frame movably coupled to the upper end of the at least one vertical member and having a plurality of photovoltaic cells mounted thereon, said shade frame being moveable between an operable position in which the shade frame provides shade and the photovoltaic cells are exposed to sunlight and a stowage position in which the shade frame is folded against the at least one vertical member; and an actuating mechanism for moving the shade frame between the operable and stowage positions.

[0010] According to a third aspect of the present invention, there is provided a solar shade system for a vehicle, said system including a shade frame movably coupled to a vertical support structure and having a plurality of photovoltaic cells mounted thereon, said shade frame being moveable relative to the vertical support structure between an operable position in which the shade frame provides shade and the photovoltaic cells are exposed to sunlight and a stowage position in which the shade frame is folded against the vertical support structure; and an actuating mechanism for moving the shade frame between the operable and stowage positions; and an energy storage system electrically connected to the plurality of photovoltaic cells for receiving, regulating and storing electrical energy supplied from the cells.

[0011 ] According to a fourth aspect of the present invention, there is provided a solar shade system for a vehicle, said system including a shade frame movably coupled to a vertical support structure and having a plurality of photovoltaic cells mounted thereon, said shade frame being moveable relative to the vertical support structure between an operable position in which the shade frame provides shade and the photovoltaic cells are exposed to sunlight and a stowage position in which the shade frame is folded against the vertical support structure; and an actuating mechanism for moving the shade frame between the operable and stowage positions; an energy storage system electrically connected to the plurality of photovoltaic cells for receiving, regulating and storing electrical energy supplied from the cells; and a controller operatively associated with the actuating mechanism, said controller configured to activate the actuating mechanism to selectively move the shade frame to maximise sunlight exposure of the plurality of photovoltaic cells.

[0012] According to a fifth aspect of the present invention, there is provided a solar shade system for a vehicle, said system including: at least one vertical member having a lower end, an opposed upper end and an elongate body extending therebetween, said lower end mountable to a support surface for supporting said vertical member in an erect position; a shade frame movably coupled to the upper end of the at least one vertical member and having a plurality of photovoltaic cells mounted thereon, said shade frame being movable between an operable position in which the shade frame provides shade and the photovoltaic cells are exposed to sunlight and a stowage position in which the shade frame is folded against the at least one vertical frame member; an actuating mechanism for moving the shade frame between the operable and stowage positions; and an energy storage system operatively associated with the at least one vertical member for receiving, regulating and storing electrical energy supplied from the plurality of photovoltaic cells.

[0013] According to a sixth aspect of the present invention, there is provided a solar shade system for a vehicle, said system including: at least one vertical member having a lower end, an opposed upper end and an elongate body extending therebetween, said lower end mountable to a support surface for supporting said vertical member in an erect position; a shade frame movably coupled to the upper end of the at least one vertical member and having a plurality of photovoltaic cells mounted thereon, said shade frame being movable between an operable position in which the shade frame provides shade and the photovoltaic cells are exposed to sunlight and a stowage position in which the shade frame is folded against the at least one vertical frame member; an actuating mechanism for moving the shade frame between the operable and stowage positions; an energy storage system operatively associated with the at least one vertical member for receiving, regulating and storing electrical energy supplied from the plurality of photovoltaic cells; and a controller operatively associated with the actuating mechanism, said controller configured to activate the actuating mechanism to selectively move the shade frame to maximise sunlight exposure of the plurality of photovoltaic cells.

[0014] Advantageously, the solar shade and solar shade system of the present invention may be readily used in both a residential and commercial setting for generating electrical energy for recharging an electric vehicle, for example. By being configured for outside use, the present invention enables an electric vehicle to be safely charged without any risk of an in-garage battery explosion. Further and by way of the actuating mechanism and movement between the operable and stowage positions, the solar shade may be readily maintained and cleaned without risk of injury or expense. Lastly, the present invention provides an aesthetically pleasing alternative to existing commercial solar car ports that contributes to, rather than detracts from, the visual appearance of a residential home.

[0015] As indicated above, the present invention provides a solar shade and car port primarily intended for a residential setting for recharging an electric vehicle and hereinafter will be described with reference to this example application. However, a person skilled in the art will appreciate that the solar shade system is capable of broader applications, such as, e.g., in a commercial setting, as a bus stop shelter or as a shade or shelter in open malls and public squares.

[0016] The shade frame may be of any suitable size, shape and construction and may be formed from any suitable materials or materials. Generally, the frame may be formed from metal and/or plastic material or materials, preferably metal, more preferably steel.

[0017] The shade frame may be of unitary construction or may be formed from two or more shade frame members, preferably the latter.

[0018] The shade frame may be substantially planar and elongate. The frame may be of any suitable shape. For example, the frame may have a rounded or polygonal shape. In some embodiments, the frame may have a circular, semi-circular or oval shape. In other embodiments, the frame may be in the shape of a triangle, square, rectangle, pentagon, hexagon or octagon. In preferred embodiments, the frame may have a substantially rectangular shape.

[0019] The shade frame may have a pair of opposed surfaces extending substantially parallel to one another. The opposed surfaces may include an upper surface and an opposed lower surface interconnected by opposing sides. The opposing sides may include a pair of opposed ends and a pair of opposed longitudinal sides.

[0020] The shade frame may be formed from two or more frame members joined together. For example, the frame may include at least a pair of parallel frame members extending longitudinally between the opposed ends. The pair of parallel frame members may be joined together by one or more transversely extending cross frame members. The frame members may be joined together using conventional welding techniques and/or one or more mechanical fasteners.

[0021 ] The frame members may be of tubular or solid construction and may have a substantially circular or rectangular cross-section, preferably tubular with a substantially rectangular cross-section.

[0022] The plurality of photovoltaic cells may be mounted on the upper surface of the shade frame in any suitable way such that they face substantially upwards when the shade frame is in the operable position.

[0023] Generally, the plurality of photovoltaic cells may be provided in one or more photovoltaic modules mounted to the upper surface of the shade frame. For example, the shade frame may include two, three, four, five, six, seven, eight, nine or ten or more photovoltaic modules. The photovoltaic modules may preferably be bifacial photovoltaic modules.

[0024] Advantageously, the use of bifacial photovoltaic modules enables the system to produce substantially more electrical energy than monofacial photovoltaic modules.

[0025] The plurality of photovoltaic modules may be mounted to the shade frame in any suitable way.

[0026] Normally, the modules may each be mounted by two or more brackets or clamps configured to hook or clamp about an outer edge of the module and be fastened to the shade frame, typically with one or more mechanical fasteners.

[0027] In some embodiments, the modules may be mounted to the shade frame with a mounting or racking system fastened to one or more frame members of the shade frame.

[0028] The photovoltaic modules may be arranged in an edge-to-edge manner atop the upper surface of the shade frame, preferably in an array. Although in some embodiments, one or more gaps may be deliberately defined between rows of photovoltaic modules to provide a pleasing aesthetic affect.

[0029] As indicated, the shade frame is movably coupled to a vertical support surface or a vertical member so as to be movable between the operable and stowage positions, typically about one axis of rotation. The vertical support surface may include a side wall of a structure, such as, e.g., a house, a shed or a wall. The vertical member will be described later.

[0030] The shade frame may be movably coupled to one of the vertical support surface and the vertical member in any suitable way, typically pivotally coupled along or adjacent a side, preferably along or adjacent a longitudinal side.

[0031 ] For example, in some embodiments a longitudinal side edge of the shade frame and one of the vertical support surface and vertical member may each include one or more protruding lugs each having a central bore therethrough. The protruding lugs may be configured to intermesh and be pinned together by at least one pivot pin received through the co-aligned central bores. The shade frame may pivot relative to the vertical support surface or vertical member about a longitudinal axis of the at least one pivot pin between the operable and stowage positions.

[0032] In other embodiments, the shade frame and the one of the vertical support surface and the vertical member may be hingedly connected together by at least one hinge so that the shade frame may be pivotable relative to the vertical support surface or the vertical member between the operable and stowage positions. The hinge may include a first hinge part operatively associated with a side of the shade frame and a second hinge part configured to be pivotally coupled to the first hinge part and operatively associated with the vertical support surface or the vertical member.

[0033] In one preferred embodiment, the shade frame and the vertical member may be pivotally coupled together by a pair of angled lugs. The angled lugs may be of any suitable size, shape and construction and may be formed from any suitable material or materials, preferably steel.

[0034] The angled lugs may extend upwards and outwards from the at least one vertical member at least partially towards the shade frame.

[0035] Each angled lug may be pivotally coupled to one or more respective shade frame lugs with one or more pivot pins. The shade frame lugs may be located on a lower surface of the shade frame at or near a longitudinal side nearest the at least one vertical member.

[0036] Advantageously, in embodiments in which the shade frame lugs may be located near a longitudinal side, the shade frame may at least partially overhang the at least one vertical member thereby increasing the solar energy capturing surface area of the shade frame on which the plurality of photovoltaic cells may be mounted. For example, in some such embodiments, the shade frame may be centrally mounted atop the vertical member such that the solar shade system has a substantially T-shaped profile when in the operable position.

[0037] In some embodiments, the shade frame may be movable about two axes of rotation relative to the vertical support surface or the vertical frame member. For example, the shade frame may be pivotable about a first axis of rotation between the operable and stowage positions and may be pivotable about a second axis of rotation to enable the shade frame to tilt or at least partially pivot to either side relative to the vertical support surface or the vertical frame member.

[0038] In such embodiments, one of the protruding lugs and hinge parts may further be rotatably coupled to one of the shade frame and the vertical support surface or vertical member to enable the shade frame to tilt or at least partially pivot relative to vertical support surface or the vertical frame member.

[0039] Any suitably type of rotational coupling may be used. Typically, the rotational coupling may include a rotatable portion operatively associated with one of the shade frame and the vertical support surface or vertical member and a non-rotatable portion rotatably coupled to the rotatable portion and operatively associated with the other of the shade frame and the vertical support surface or vertical member.

[0040] Typically, the shade frame may be pivotable by about ±5°, about ±10°, about ±15°, about ±20°, about ±25°, about ±30°, about ±35°, about ±40°, about ±45° or more from a horizontal plane relative to the vertical support surface or the vertical frame member.

[0041 ] As indicated, the shade or system includes an actuating mechanism for moving the shade frame between the operable and stowage positions. Any suitable type of actuating mechanism may be used. The actuating mechanism may be manually actuated or by using a drive motor. Movement may be linear or non-linear, such as, e.g., rotary. Movement may be provided by a linear or screw actuator, a rotary or planetary gearing, or a pretensioned spring mechanism in combination with one or more of cables, pillows and counterweights, or any combination thereof, for example.

[0042] For example, if manually actuated, the actuating mechanism may include one or more of a lever, ram, operable handle, sliding arrangement, hinged arrangement or pivoting arrangement for moving the shade frame relative to the vertical support surface or vertical member.

[0043] The actuating mechanism may include one or more biasing members or mechanisms.

[0044] In some embodiments, movement of the shade frame to the operable position may work against the biasing force of the biasing member or mechanism, so that movement to the stowage position works under the biasing force of the biasing member or mechanism.

[0045] Conversely and in preferred embodiments, movement of the shade frame to the operable position may work under the biasing force of the biasing member or biasing mechanism, and movement to the stowage position may work against the biasing member or mechanism.

[0046] Advantageously, by having movement of the shade frame to the stowage position work against the biasing force of the biasing member or mechanism, the shade frame may be at least partially prevented from rapidly folding into the stowage position and potentially striking an underlying vehicle, person or object.

[0047] Any suitable drive motor may be used.

[0048] For example, movement of the shade frame about the first axis of rotation between the operable and stowage positions may be driven by a linear actuator capable of moving between extended and retracted positions corresponding to the operable and stowage positions. The linear actuator may be of any suitable size, shape and form and may be associated with the shade frame and the vertical support surface or vertical member in any suitable way.

[0049] For example, in some embodiments, the linear actuator may be a pneumatic or hydraulic ram.

[0050] Conversely, in other embodiments, the linear actuator may be a servomotor or stepper motor configured to raise and lower the shade frame relative to the vertical support surface or vertical member between the operable and stowage positions.

[0051 ] In yet further embodiments, the linear actuator may include a rigid chain actuator (also known as a linear chain actuator, push-pull chain actuator, electric chain actuator, zip chain actuator or column-forming chain actuator).

[0052] In yet other embodiments, the actuating mechanism may include a drive mechanism including a drive spool or drive wheel mounted to vertical support surface or vertical member and a drive line extending between the drive spool or drive wheel and an outer longitudinal side of the shade frame. The drive spool or drive wheel may be powered and configured to wind in and out the drive line to move the shade frame between the operable and stowage positions, respectively.

[0053] Movement of the shade frame about second axis of rotation may be driven by any torque applying machine or device. For example, movement may be driven by an electric motor or combustion engine operatively associated with the rotational coupling.

[0054] The vertical member may be of any suitable size, shape and construction and may be formed from any suitable material or materials to be mounted to a support surface in an erect position and support the shade frame.

[0055] Generally, the vertical member may be formed from metal and/or plastic material or materials, preferably metal, more preferably steel.

[0056] The vertical member may be of unitary construction or may be formed from two or more vertical member pieces.

[0057] As indicated, the vertical member includes a lower end, an opposed upper end and an elongate body extending therebetween.

[0058] In some embodiments, the vertical member may include a vertical frame member, such as, e.g., an I-beam, a T-beam, or a column, the latter of which may have any suitable cross- sectional shape, preferably square or circular.

[0059] In other embodiments, the vertical member may include two or more vertical frame members joined together. For example, the vertical member may include at least a pair of vertically orientated frame members extending longitudinally between opposed ends. The pair of frame members may be joined together by one or more transversely extending cross frame members. [0060] The frame members may be of tubular or solid construction and may have any suitable cross-sectional shape, such as, e.g., circular, rectangular or triangular. Preferably, the at least the two or more vertical frame members may be of tubular construction with a substantially rectangular or circular cross-sectional shape.

[0061 ] The frame members may be joined together using conventional welding techniques or one or more mechanism fasteners, for example.

[0062] In such embodiments, the vertical member may further include a housing or outer shell at least partially covering the vertical frame member or frame members. The housing or outer shell may define the outer shape of the vertical member, which may be circular, ovalshaped, triangular or rectangular, for example.

[0063] The housing or shell may be of unitary construction configured to be wrapped about the vertical member or may include two or more panels configured to be connected in a side edge-to-side edge arrangement about the vertical member, preferably the latter.

[0064] The panels may be formed from metal, plastic, glass, fibre, concrete, stone and/or wood material or materials, preferably metal and/or plastic material or materials, more preferably metal material or materials, such as, e.g., aluminium, titanium or a composite thereof.

[0065] The panels may be mesh or may include a decorative motif, shape or word(s). For example, the panels may include one or more perforated openings arranged to create the decorative motif, shape or word(s).

[0066] One or more of the panels may be removable or hingedly connected so as to be access panels.

[0067] In yet other embodiments, the vertical member may include a vertical preformed construction element defining a column, for example. The vertical preformed element may have a cementitious body, preferably including one or more reinforcing members at least partially embedded in the body.

[0068] The vertical member may be mountable to a support surface to support the vertical member in an erect position in any suitable way, preferably detachably.

[0069] Advantageously, by being detachably mounted to the support surface, the solar shade is portable and thus may move with an owner when he or she relocates, for example. This may be particularly attractive to non-owner occupiers of residential properties. [0070] In some embodiments, the lower end of the vertical member may be mounted to the support surface by one or more mechanical fasteners.

[0071 ] In other embodiments, the lower end of the vertical frame member and the support surface may be connected together by a connecting mechanism or part of a connecting mechanism.

[0072] The connecting mechanism may include a first part associated with the lower end of the vertical member and a second part connectable to the first part and associated with the support surface.

[0073] The parts of the connecting mechanism may include mateable male and female formations that couple or mate together, including a threaded connection, an interference (snap- fit) connection or a bayonet-type connection, for example.

[0074] In some embodiments, a first part of the connecting mechanism associated with the lower end of the vertical member may include a male formation configured to be inserted into or coupled with a female formation of a second part of the connecting mechanism associated with the support surface.

[0075] Conversely, in other embodiments, the first part of the connecting mechanism associated with the lower end of the vertical member may include a female formation configured to at least partially receive or couple with a male formation of the second part of the connecting mechanism associated with the support surface.

[0076] In some embodiments, the lower end of vertical member may be mounted atop a foundation, such as, e.g., a plastic, metal and/or cement foundation.

[0077] The foundation may be a deep foundation.

[0078] The foundation may include one or more pilings, such as, e.g., screw-in pilings for at least partially anchoring the foundation and providing a stable support base for the at least one vertical member.

[0079] The one or more screw-in piles may be coupled to the foundation at an upper end and may be configured to be driven into a ground surface.

[0080] In preferred embodiments, the at least one vertical member may be anchored to a ground surface with a foundation system including a screw-in piling and a connecting cap configured to be fastened atop an upper end of the screw-in piling and have a lower end of the at least vertical member detachably fastened thereon.

[0081 ] The screw-in piling may include a lower end configured to be driven into a ground surface, an opposed upper head portion and a cylindrical body extending therebetween. The cylindrical body may include one or more outwardly extending helical spiral flanges for engaging with a ground substrate and forming a stable and solid anchor.

[0082] The connecting cap may be configured to threadingly engage with a threaded portion provided on the head portion of the screw-in piling to connect them together.

[0083] The connecting cap may be configured to be mechanically fastened to a lower end portion of the one or more vertical frame members forming the at least one vertical member with one or more mechanical fasteners.

[0084] Preferably, shaped openings may be defined in both the cap and the head portion of the screw-in piling for at least partially receiving a lower end of a vertical frame member therethrough, when the connecting cap is threadingly engaged with the head portion of the screw-in piling and the respective shaped openings are co-aligned.

[0085] In some embodiments, the at least one vertical member may include a swivel mechanism for enabling an upper portion of the vertical member including the shade frame to swivel or rotate relative to a lower portion of the vertical member.

[0086] The swivel mechanism may be of any suitable size, shape and form and may be located in any suitable location along the elongate body, typically at or near the upper end.

[0087] Typically, the swivel mechanism may include a rotational portion and a non-rotational portion rotatably coupled together and each operatively associated with one of the lower portion and the upper portion of the vertical member.

[0088] In some embodiments, the swivel mechanism may include a drive for driving rotational movement, such as, e.g., an electric motor or the like.

[0089] In some embodiments, the foundation may further include at least one earthing or grounding electrode. The at least one earthing or grounding electrode may be of any suitable size, shape and construction and may be associated with the foundation in any suitable way.

[0090] Generally, the at least one earthing or grounding electrode may be in the form of a rod, preferably formed from an electrically conductive material or materials, such as, e.g., metal or carbon. [0091 ] In preferred embodiments, the at least one earthing or grounding rod may extend along and through a screw-in piling as described above.

[0092] As indicated, the system includes an energy storage system electrically connected to the plurality of photovoltaic cells for receiving, regulating and storing electrical energy supplied from the plurality of photovoltaic cells.

[0093] The energy storage system may be of any suitable size, shape and form and may be located in any suitable location relative to a remainder of the system. For example, in some embodiments, the energy storage system may be at least partially housed in the vertical member, specifically the housing of the vertical member.

[0094] Generally, the energy storage system may include one or more batteries connected to the plurality of photovoltaic cells and their associated inverter via a rectifier circuit and/or other circuitry, including a regulator circuit. The rectifier circuit may convert the alternating current generated by the inverter to a direct current. The regulator circuit may ensure correct charging of the one or more batteries. Further, the regulator circuit may prevent transferring over voltages to the one or more batteries to enhance battery performance and lifespan.

[0095] Typically, the rectifier circuitry and/or other circuitry may be positioned within housing of the energy storage system. In some embodiments, at least the regulatory circuit may be integrated with the one or more batteries.

[0096] In some embodiments, the energy storage system may further include one or more voltmeters for measuring voltage input into the rectifier circuit and the one or more batteries.

[0097] Electrical energy stored in the one or more batteries may be concurrently or later used in other elements of the solar shade, such as, e.g., for powering actuating mechanisms of the shade frame and/or lighting systems.

[0098] In some embodiments, the energy storage system may further include at least one electric car charging station electrically connected to the one or more batteries for supplying electrical energy to an electric vehicle. The electric car charging station may be of any known form in the art. For example, the electric car charging station may be a fast charging unit, a wireless charging unit, and/or a retractable wired or wireless charging unit. In some such embodiments, the electric car charging station may be capable of bi-directional charging.

[0099] The electric car charging station may be concealed behind an access panel of the housing of the at least one vertical member. [00100] As indicated above, the system may include a controller operatively associated with the actuating mechanism, and preferably also the energy storage system. The controller may be configured to activate the actuating mechanism to selectively move the shade frame to maximise sunlight exposure of the plurality of photovoltaic cells.

[00101] The controller may include a dedicated microprocessor or microcomputer, including one or more processors and a memory, operatively associated with the actuating mechanism and/or the energy storage system for collecting data corresponding to a position of the solar shade and electrical energy generated and stored by the photovoltaic cells and the one or more batteries.

[00102] Generally, the system may include one or more sensors. The one or more sensor may include one or more proximity sensors and one or more environmental sensors for monitoring environmental conditions, such as, sunlight direction and wind speed. The one or more sensors may be operatively connected to the controller. The one or more environmental sensors may include light sensors and wind speed sensors.

[00103] For example, in some embodiments, the one or more environmental sensors may sense a sunlight direction and transmit data indicative of the sunlight direction to the controller. Upon receiving the data, the controller may activate the actuating mechanism to selectively move the shade frame and the photovoltaic cells mounted thereon to minimise an angle of incidence between the sunlight direction sensed and the photovoltaic cells thereby maximising sunlight exposure of the plurality of photovoltaic cells.

[00104] In other embodiments, the one or more environmental sensors may sense an increase in wind speed indicative of an imminent weather event and may transmit data indicative of the wind speed to the controller. Upon receiving the data, the controller may activate the actuating mechanism to selectively move the shade frame and the photovoltaic cells mounted thereon to a stable position, such as, e.g., a horizontal plane or the stowage position.

[00105] In other embodiments, the one or more proximity sensors may be configured to sense whether there is an object, such as, e.g., a vehicle, beneath the shade frame. In such instances, the one or more sensors may transmit data indicative of the presence of an object beneath the shade frame to the controller. The controller, upon receiving the data from the one or more environmental sensors, may isolate the actuating mechanism to prevent movement of the shade frame to prevent any damage to the shade frame and any object underneath the frame.

[00106] Generally, data received from the one or more proximity sensors may overrule data received from the one or more environmental sensors.

[00107] In some embodiments, the one or more sensors may include an image capturing device, such as, e.g., a camera, capable of detecting the presence of an object beneath the shade frame.

[00108] Typically, the controller may also monitor and control the energy storage system. For example, the controller may receive data from the one or more voltmeters indicative of a charge level of the one or more batteries and/or solar input electricity. Any irregularities and/or errors identified by the controller may be reported to a user.

[00109] The system may further include a communications module for connecting the system to an external device, such as, e.g., an external processing device, a remote controller, a remotely accessible server, an external display or storage device. The system may be connected to the external device in any suitable way.

[00110] For example, in some such embodiments, the communications module may be in the form of a port or access point (e.g., a USB or mini-USB port) such that the system may be connected to the external device using a suitable cable.

[0011 1] In other such embodiments, the communications module may be in the form of a wireless communications module, such as, e.g., a wireless network interface controller, such that the system may wirelessly connect to the external device via a wireless network, e.g., a WiFi (WLAN) communication, Satellite communication, RF communication, infrared communication or Bluetooth™). In such embodiments, the communications module may include at least one modem, such as, e.g., a cellular or radio modem.

[00112] In some embodiments, the controller may be a remote controller. The remote controller may be of any suitable size, shape and form.

[00113] The remote controller may include one or more keys, buttons and/or switches for an operator to control operation of the system.

[00114] In some embodiments, the remote controller may include at least one display for displaying data transmitted from the system, such as, e.g., a charge level of the one or more batteries.

[00115] In some embodiments, the remote controller may be an external computing device, such as, e.g., a laptop, a desktop or a remotely accessible server. In such embodiments, the device may further include software configured to be run on the computing device for controlling operation of the system. The software may preferably be interactive and allow an operator to interact and control operation of the system, or at least aspects of the system.

[00116] In other embodiments, the remote controller may be a mobile computing device, such as, e.g., a smart phone, a tablet or a smart watch. In such embodiments, the remote controller or device may further include software in the form of an application (i.e., an app) configured to be run on the mobile computing device and allowing an operator to interact and control the system, or at least aspects of the system.

[00117] For example, in some embodiments, the software may allow a user to selectively control whether generated electricity is stored in the energy storage system or is a diverted to another destination, such as, e.g., to power other electrical components of the house or back into the grid.

[00118] In other embodiments, the software may provide an online platform where a user may rent their solar shade for a period of time. For example, a user may rent the use of their solar shade during a day when they may not otherwise be using it.

[00119] In some embodiments, the shade or system may further include one or more wind turbines for generating electrical energy. The one or more wind turbines may be of any suitable size, shape and form to be mounted on the shade frame.

[00121] Preferably, the one or more wind turbines may be mounted along opposed longitudinal sides of the shade frame.

[00122] Typically, the one or more wind turbines may be used when there is insufficient sunlight, such as, e.g., in temperate climates and/or at night, or alternatively may be used to complement the photovoltaic modules on a windy day. In some such embodiments, the one or more wind turbines may be pop-up wind turbines configured to be concealed in a cavity in the shade frame when not in use.

[00123] For example, the one or more wind turbines may be operatively connected to the one or more sensors, the controller and the energy storage system. In use, the one or more sensors may sense insufficient sunlight for solar electrical energy generation and transmit data indicative data indicating this to the controller. The controller, upon receiving the data, may selectively activate the one or more wind turbines for the generation of electrical energy.

[00124] In some embodiments, the solar shade or system may include a lighting system for illuminating underneath the shade frame. The lighting system may include one or more lights mounted in a lower surface of the shade frame and the at least one vertical member, if present.

[00128] For example, in some such embodiments, the one or more lugs connecting the vertical member to the shade frame may slide relative to the vertical member to enable wide shade frames to be moved between the operable and stowage positions.

[00129] In other such embodiments, the one or more lugs connecting the vertical member to the shade frame may slide relative to the vertical member to adjust a height of the shade frame to maximise sunlight exposure of the one or more photovoltaic cells. For example, the shade frame may be raised or lowered via the one or more lugs to maximise sunlight about or around a nearby tree.

[00130] The system may include a further actuating mechanism for moving the one or more lugs along a height of the vertical member. The actuating mechanism may preferably be linear actuator as previously described, more preferably screw actuators.

[00135] The shade may include one or more of the characteristics or features of the solar shade and solar shade system as hereinbefore described.

[00136] Typically, the shade may further include a controller operatively connected to the actuating mechanism and the energy storage system for at least selectively moving the louvre blades between the open and closed position to maximise sunlight exposure of the photovoltaic cells and for monitoring a charge level of the one or more batteries of the energy storage system.

DETAILED DESCRIPTION

[00165] Figures 1 to 7 show a solar shade system (100) and parts thereof according to embodiments of the present invention.

[00166] Referring to Figures 1 and 2, the solar shade system (100) includes a vertical member (1 10) mountable to support surface (120) in an erect position; and a shade frame (130) movably coupled to an upper end (1 12) of the vertical member (1 10) and having a plurality of photovoltaic cells (140) mounted thereon.

[00167] The shade frame (130) is movable between an operable position, as shown in Figure 1 , in which the shade frame (130) provides shade and the photovoltaic cells (140) are exposed to sunlight, and a stowage position, as shown in Figure 2, in which the shade frame (130) is folded against the vertical member (1 10).

[00168] The solar shade system (100) further includes: an actuating mechanism in the form of a pair linear actuators (300; shown only in Figures 3 and 4) for moving the shade frame (130) between the operable and stowage positions; an energy storage system (610; shown only in Figure 6) operatively associated with the vertical member (1 10) for receiving, regulator and storing electrical energy generated from the plurality of photovoltaic cells (140); and a controller operatively associated with the actuating mechanism and energy storage system for activating the actuating mechanism to selectively move the shade frame (130) and track a position of the sun to maximise sunlight exposure of the plurality of photovoltaic cells (140).

[00169] Referring to Figure 1 , the shade frame (130) is substantially planar and elongate. The frame (130) has a rectangular shape and includes a pair of opposed surfaces, including an upper surface (132) and an opposed lower surface (134) interconnected by opposing sides. The opposing sides include a pair of opposed ends (136) and a pair of opposing longitudinal sides (138) extending therebetween.

[00170] The shade frame (130) is formed from two or more frame members (131 ) joined together.

[00171] The plurality of photovoltaic cells (140) are mounted on the upper surface (132) of the shade frame (130).

[00172] The plurality of photovoltaic cells (140) are provided in photovoltaic modules (142) mounted to the upper surface (132) of the shade frame (130). As shown, the shade frame (130) supports 12 photovoltaic modules (142). The photovoltaic modules (142) are bifacial photovoltaic modules (142).

[00173] The photovoltaic modules (142) are mounted to the shade frame (130) with a mounting or racking system fastened to the one or more frame members (131 ) of the shade frame (130).

[00174] The photovoltaic modules (142) are arranged in an edge-to-edge manner atop the upper surface (132) of the shade frame (130) in an array.

[00175] As shown, the shade frame (130) is pivotally coupled to the vertical member (1 10) along a longitudinal side (138).

[00176] The vertical member (110) has the upper end (112), an opposed lower end (1 14) and an elongate body (116) extending therebetween.

[00177] As mentioned, the shade frame (130) is pivotally coupled to the upper end (1 12) and the lower end (1 14) is detachably mounted to the support surface (120) via a foundation system (500), which will be described in detail later in relation to Figure 5.

[00178] The vertical member (1 10) is formed from steel and is formed from two vertical frame members (1 18) joined together by one or more transversely extending cross frame members (1 19; visible in Figures 3 and 4). The frame members (1 18, 1 19) are joined together using conventional welding techniques.

[00179] The vertical member (1 10) further includes a housing (1 11 ) for covering the frame members (1 18, 119 - not visible) and enclosing the controller and the energy storage system (610; shown only in Figure 6).

[00180] The housing (1 11 ) includes two or more panels configured to be connected in a side edge-to-side edge arrangement about the vertical member (110). The panels are formed from metal and include a decorative motif (119).

[00181] Referring to Figures 3 and 4, the shade frame (130) is pivotally coupled to the vertical member (1 10) by a pair of angled lugs (310) that extend upwards and outwards from the vertical member (110) at least partially towards the shade frame (130). Each angled lug (310) is pivotally coupled with a pivot pin to one or more respective shade frame lugs (330) located on the lower surface (134) of the shade frame (130) adjacent a longitudinal side (138) nearest the vertical member (1 10).

[00182] The shade frame (130) and the vertical member (1 10) are further interconnected by a pair of linear actuators (300) each capable of moving between a retracted position, as shown in Figure 3, corresponding to the operable position, and an extended position, as shown in Figure 4, corresponding to the stowage position.

[00183] The height of the vertical member (1 10) is adjustable by way of a further pair of linear actuators (400) mounted between an anchor point in the form of a cross frame member (1 19) and a lower end of the co-joined angled shade frame lugs (310).

[00184] The further pair of linear actuators (400) are each capable of moving between a retracted position, as shown, and an extended position for increasing a height of the vertical member (1 10) and, thus, a height of the shade frame (130) above the support surface (120).

[00185] Referring to Figure 5, the lower end (1 14; not shown) of the vertical member (100; not shown) is detachably mounted to the support surface (120; not shown) via a foundation system (500).

[00186] The foundation system (500) includes a screw-in piling (510) and a connecting cap (520) configured to couple to a lower end of each vertical frame member (118) forming the vertical member (1 10; not shown).

[00187] The screw-in piling (510) includes a pointed lower end (512); an opposed upper head portion (514); and a cylindrical body (516) extending therebetween. The cylindrical body (516) includes one or more outwardly extending helical spiral flanges (518) for engaging with a ground substrate and forming a solid and stable foundation.

[00188] The connecting cap (520) is configured to threadingly engage with a threaded portion of the head portion (514) of the screw-in piling (510) to connect them together.

[00189] The connecting cap (520) is configured to be mechanically fastened to a lower end portion of the vertical frame member (1 18) forming the vertical member (1 10; not shown) with one or more mechanical fasteners.

[00190] Shaped openings (530) are defined in both the cap (520) and the head portion (514) of the screw-in piling (510) for at least partially receiving the lower end of the vertical frame member (1 18) therethrough, when co-aligned.

[00191] Referring to Figure 6 and as indicated, the system (100) includes the energy storage system (610) for receiving, regulator and storing electrical energy generated from the plurality of photovoltaic cells (140). The energy storage system (610) in this embodiment includes an integrated electric car charging station.

[00192] The energy storage system (610) is electrically connected to the photovoltaic cells (140) and is housed within the vertical member (110) behind an access panel (shown removed).

[00193] The system (610) includes one or more batteries connected to the plurality of photovoltaic cells (140) and their associated inverter via a rectifier circuit and/or other circuitry, including a regulator circuit.

[00194] The rectifier circuit converts the alternating current generated by the inverter to a direct current. The regulator circuit ensures correct charging of the one or more batteries. Further, the regulator circuit prevents transferring over voltages to the one or more batteries to enhance battery performance and lifespan.

[00195] The energy storage system (610) further includes one or more voltmeters for measuring voltage input into the rectifier circuit and the one or more batteries.

[00196] Electrical energy stored in the one or more batteries can be concurrently or later used in other elements of the solar shade system (100), such as, e.g., for powering the linear actuators (300, 400; not shown) and/or lighting systems.

[00197] As previously mentioned, the system (100) includes a controller operatively associated with the actuating mechanism and the energy storage system (610). The controller is configured to activate the actuating mechanism to selectively move the shade frame (130) to track a position of the sun.

[00198] The controller includes a dedicated microprocessor or microcomputer, including one or more processors and a memory, operatively associated with the actuating mechanism and/or the energy storage system (610) for collecting data corresponding to a position of the shade frame (130) and electrical energy generated and stored by the photovoltaic cells (140) and the one or more batteries.

[00199] The system (100) further include one or more sensors for monitoring environmental conditions, such as, sunlight direction and wind speed. The one or more sensors are operatively connected to the controller. The one or more sensors include light sensors.

[00200] In use, the one or more sensors are configured to sense a sunlight direction and transmit data indicative of the sunlight direction to the controller. Upon receiving the data, the controller activates the actuating mechanism to selectively move the shade frame (130) and the photovoltaic cells (140) mounted thereon to minimise an angle of incidence between the sunlight direction sensed and the photovoltaic cells (140) thereby maximising sunlight exposure of the plurality of photovoltaic cells (140).

[00201] The controller is also configured to monitor and control the energy storage system (610). For example, the controller receives data from the one or more voltmeters indicative of a charge level of the one or more batteries and/or solar input electricity. Any irregularities and/or errors identified by the controller are reported to a user.

[00202] The system (100) further includes a communications module for connecting the system (100) to an external device, such as, e.g., an external processing device, a remote controller, a remotely accessible server, an external display or storage device. The system (100) can be connected to the external device in any suitable way. The communications module includes a cellular or radio modem so that the system (100) can wirelessly connect to the external device via a wireless network, e.g., a Wi-Fi (WLAN) communication, Satellite communication, RF communication, infrared communication or Bluetooth™).

[00203] Referring to Figure 7, the solar shade system (100) includes a lighting system (710) for illuminating underneath the shade frame (130). The lighting system (710) includes one or more lighting units (712) mounted on a lower surface (134) of the shade frame (130) and the vertical member (110). The lighting system (710) draws power from the energy storage system (610; not visible).

[00205] Referring to Figure 8, the solar car port system (800) includes at least one pair of the solar shade system (100) arranged opposite one another such that the shade frame (130) from each solar shade system (100) extends therebetween providing shade and exposing the photovoltaic cells (140) mounted thereon to sunlight.

[00206] The solar car port system (800) can be provided to any desired length by adding further pairs of the solar shade system (100) in series to a first pair.

[00207] Further, the solar car port system (800) can be expanded to be a multi-vehicle solar car port system (800) by adding further pairs of the solar shade system (100) in parallel to the first pair.

14. The solar shade of any one of claims 4 to 13, wherein the energy storage system further includes at least one electric vehicle charging station for supplying the electrical energy stored to an electric vehicle.

15. The solar shade of any one of claims 5 to 14, further including one or more sensors operatively connected to the controller, said one or more sensors including proximity sensors, light sensors and wind speed sensors.

16. The solar shade of claim 15, wherein the light sensors sense a sunlight direction and transmit data indicative of the sunlight direction to the controller, which activates the actuating mechanism to selectively move the shade frame and the photovoltaic cells mounted thereon to minimise an angle of incidence between the sunlight direction sensed and the photovoltaic cells to thereby maximise sunlight exposure of the plurality of photovoltaic cells.

17. The solar shade of claim 15 or claim 16, wherein the wind speed sensors sense a change in wind speed indicative of an imminent weather event and transmit data indicative of the change in wind speed to the controller, which activates the actuating mechanism to selectively move the shade frame and the photovoltaic cells mounted thereon to a stable position.

18. The solar shade of any one of claims 15 to 17, wherein the proximity sensors are configured to sense an object located in a direction of movement of the shade frame and transmit data indicative of a presence of the object to the controller, which isolates the actuating mechanism to prevent movement of the shade frame until the object has moved or been removed.

19. The solar shade of any one of claims 1 to 18, further including one or more wind turbines for generating electrical energy when there is insufficient sunlight and/or for complementing the plurality of photovoltaic cells.

20. The solar shade of any one of claims 3 to 19, wherein the at least one vertical member is adjustable to adjust a height of the shade frame above the support surface.

21 . A solar car port for at least one vehicle, said car port including at least a pair of solar shades according to any one of claims 1 to 20 and arranged opposite one another such that the shade frame from each solar shade extends therebetween to provide shade for the at least one vehicle located underneath.
