The present invention relates primarily to a field of solar panels, and more particularly it relates to a novel system for mounting solar panels onto buildings and other structures including, but not limited to, solar farms.
There has been a little change on mounting solutions for solar panels onto buildings and other structures, with expensive and cumbersome aluminum extrusions and clips being used traditionally. Additionally, there have been no advancements in mounting hardware such as conduits, conductors, and micro-inverters onto building facades for Building Integrated Photovoltaics which are mounted over exterior insulation. For solar panel power conversion efficiency (PCE) in relation to deflected or reflected light, there have been no great advancements without significant losses to PCE.
Hence, there is a significant need and void in the market to invent novel and improved solar mounting solutions. The present invention is hereinafter disclosed, which provides complete solar mounting systems which address the issues listed above as well as reductions in up-front costs, increased thermal efficiency for building integrated PV, means for equipment heat dissipation, structural hardware mounting, and increased collection of solar rays resulting in less glare from solar panels.
In accordance with the present application, a novel and useful solar mounting system is hereinafter provided including specially shaped structural thermal clips, specially shaped structural and thermal mounting washers, structural hardware struts, a micro-inverter cooler/heat sink, structural solar panel mounting clips, solar panel frames, a light-directing anti reflective material, replacement reveal strips, a highly efficient dual T-slot continuous insulation mounting sub-girt with adjustable clips, structural reveal strip and their attachment method, an ACM/MCM panel stiffener, and girt stabilizers.
All shaped wire products such as the structural thermal clips, hardware struts and solar panel mounting clips will be made of fully hardened stainless or galvanized carbon steel spring wire and formed on manual or automated wire bending machines. The wires may be welded, press formed and/or twist formed together to make any conceivable shape. They may have holes or slots for mechanical fasteners to either hold them fixed or allow them to move within the slot. They may have plastics, foams, butyl materials, adhesives, self-locking washers and/or other materials added onto or adjacent to them for better thermal performance, as a safety coating including for electrical insulation, to minimize vibration (sound), or to help connect or otherwise interact with itself or other materials by being more or less sticky or prone to wear. The ends of the wires may have threads added by use of dies so that the male threaded ends can connect into female threaded attachments. The wires may be formed into coils so that when a screw is inserted into it the coil will allow the fastener to enter but reversing the screw will tighten the coils to help prevent it from backing out or cause enough additional friction to prevent the fastener from backing out. Because additional mounting holes help prevent formed wire movement and can add rigidity, all formed wires may have one or more mounting hole. The formed wires may press against and keep tension on another component, or act to keep it in a substantially fixed position. Hardware mounting struts may have one or more independent locations where conduits, conductors, pipes, and other materials may pass therethrough.
Isolators may be made using plastic injection molding processes, or sheets of stainless-steel with an adhered EPDM backer which may manufactured by a turret press. Custom washers may be made of a material such as stainless steel with or without an EPDM type of backer and manufactured with a turret press to add anti-reversal mechanisms, protrusions, and convex shapes while a break press may be used to create hems or other bends required.
The stainless steel structural thermal clips will be used over a plastic isolator or custom stainless EPDM backed washer isolators when connected to a substrate in order to help reduce thermal transfer into a building, and the isolators help spread the pressure of loads over a larger surface of the building's substrate as well as to help prevent water from entering the substrate underneath the isolators. The thermal clips' mounting holes will be formed in a clockwise direction so that the mounting holes don't try to open its shape up when a fastener is tightening, and the very end of the mounting hole wire will be formed upwards so that when the screw is completely seated the upwardly formed end will act as a compressed lock washer to prevent the screw from backing out by engaging the bottom side of the head of the fastener. These thermal clips may be triangularly shaped to obtain maximum performance for supporting loads, and the triangular shape may be made using one or more wires. The formed wires will allow for adjustability of the girts so that the building can be leveled and planed prior to façade material mounting. If movement in any direction is needed for seismic or other reasons, the formed wires can be made to be less rigid by adding length such as in the shape of coils and bends between 2 points. The wire clips can be made to accommodate vertical, horizontal, and diagonal sub-girts. The thermal clips may be used vertically for walls or horizontally for roofs and soffits.
The highly efficient dual T-slot continuous insulation mounting sub-girt and adjustable clips will be fabricated from materials such as extruded aluminum with various holes and slots machined into them with a manual or CNC milling machine. The stainless-steel panel wire clips may fit inside the T-slots and then fastened in place with a fastener positioned on top of the T-slot, or the stainless panel wires may be fastened directly to the top of the T-slots if desired. A self-sustained structural dual T-slot extrusion may be made which will allow a fastener through two or more locations before exiting and self-drilling into a steel stud or other sub-structure. This multiple point-of-contact on the fastener causes loads to be supported by the bend strength of the fasteners because the fastener is forced to hold a straight position. The T-slots may have holes drilled into them to allow a fastener head to enter through the hole so that it doesn't need to be brought in from one end or the other.
The structural solar panel mounting clips slide or snap into or onto the return legs of the solar panel frames which is shown in the drawings and don't require fasteners to mount to the panels themselves. The stainless-steel solar panel mounting clip attachment holes will be fastened into the sub-framing or substrate to permanently fix the mounting clips in a fixed position, which then supports and holds a solar panel in a fixed position as well. Some variations of the solar panel mounting clip allow for thermal expansion of a panel, and others don't, and more than one type of solar panel mounting clip may be used with a single panel. The panel wires may be made less rigid by adding coils, bends or otherwise lengthening it in general in order to allow them to flex for movements such as seismic and dynamic loads, which will allow the facade material to move without causing it to deform. On a given solar panel there may more than one type of solar panel mounting clip used.
Microinverters must be cooled to work properly. The micro-inverter cooler/heat sink is designed to keep the micro-inverter and other electric/electronic equipment away from contact with the insulation and/or solar panels, where such contact may otherwise cause equipment to overheat and malfunction. The cooler/heat sinks do this by allowing air to pass all around the devices, while at the same time helping as a heat sink to help draw some of the heat away from the device. They may compress the insulation yet still allow air flow between the insulation and device. They may be made in an extrusion process if made of aluminum with holes machined out of it; injection molded as a complete part if plastic, or 3D printed of almost any material including fiber reinforced plastics. They are designed to have minimal contact with the devices in order to block as little heat as possible. They may be made separate from the microinverters or other devices or built into the framing of the microinverter or other devices as a uni-frame and used as part of the microinverter regardless of its application. Some of the cooler/heat sink materials may be removed or eliminated to reduce materials and process costs. The cooler/heat sinks can be made to allow the microinverter to be similarly covered from all sides to prevent contact with any materials, allowing for un-interrupted cooling from all directions.
The solar panel frame may be made of a metal such as stainless steel using a turret press and brake press to form it. It may also be made of a composite material such as aluminum composite material (ACM/MCM). The frames may be adhered to the back of solar panels with an adhesive or other mechanical fastening option such as angle supports and fasteners. The frame portion adjacent to the solar panel modules may be solid, perforated, or expanded material to allow for cooling behind the panel. The returns of the solar panel frame may be used to help direct hot air out the sides of the panels and allow for cooler air to enter from other locations, such as from the bottom of the panels when they are mounted in a vertical orientation. An ACM frame, or formed aluminum sheet frame, may have a portion of the outer skin surface removed so that thin-film solar modules may be adhered to the inside of the ACM frame, mounted flush with the outside of the ACM.
The replacement reveal may be a material such as ACM/MCM or aluminum sheet which can be machined to provide holes for a fastener attached to a tool, such as a nut-driver, to pass through the holes to fasten the solar panel mounting clips to the substrate. Once the fasteners are tightened, the tool may be removed and the replacement reveal strip cover or caps may be adhesively installed for permanent fixing.
The light-directing anti reflective material (lens) will be a form of a Fresnel lens, but specific to solar panels. To best capture sunlight and direct it into the solar collectors, horizontal grooves may be used for south and north facing walls while substantially vertical grooves may be used for east and west facing walls. The direction of the grooves would be specific to the direction the building is facing in order to collect the most sunlight throughout the year at and between the winter and summer solstices. The shape of the grooves may be any shape which allows the most amount of sunlight to reach the solar collectors, such as equilateral triangle shapes or right triangle shapes, and includes consideration for the angle of incidence of the light and capturing it through an adjacent plane of an adjacent groove, whether on the same or different plane. A film which helps prevent dust build-up may be used over the outer surface for cleanliness, such as a product like Solar Share. The grooves may be on the outside where the sun first contacts the solar panel, but these grooves may also be on the inside with the anti-reflective material acting as part of the packaging for the solar module, and the interior grooves being used to further distribute the light in advantageous directions as well as to be used for better adhesion within the solar module where adhesives are used. The grooves on the outside of the panel will help prevent glare because they are redirecting the light into the solar panel or in directions other than a single direction as would a flat sheet of glass. The lens may be made of a material such as glass or plastic, and manufactured using means such as injection molding, embossing or machining.
Structural reveal strips may be made of ACM/MCM or a material such as aluminum sheet which can be stapled, clinched, or otherwise mechanically attached to differing or like materials. These structural reveal strips are commonly used for architectural purposes only, but the proposed solution makes them not only structural, but potentially waterproof is adhesive is used between them and the adjoining material. Structural reveal strips are permanently attached to the panel returns so that they create a full panel assembly which includes the reveals, where the reveals are traditionally inserted following structural attachment of the panel. The structural reveal strips attach to the returns of the panels, attach more than one return of the panel together, and help to maintain the shape of the panel by fixing the corners of the panels into specific locations. These structural reveal strips may be used on one or more sides of a panel in order to control the amount of water to enter behind the panel, as well as to control the amount of air behind the panel to evaporate any water which does get behind the panel. These structural reveal strips will generally use ACM/MCM material which would normally be scrapped because the widths are too small. Structural reveal strips may also control the amount of water which enters behind a panel and the direction the water is moved once installed. A portion of the structural reveal strip may rest inside of the flanges inside the panel cavity, and that portion may be routed and bent inwards toward the inside-back of the panel to force water into the back of the panel, where the water can then be evacuated through weep holes in the bottom of the panel and guttered away from behind the panels.
An extrusion or formed sheet metal means of making a solar panel mounting clip is possible by mimicking the shapes of the formed stainless steel solar panel mounting clips and should be considered obvious for the way these attachment systems work and are used.
A formed ACM/MCM panel stiffener to replace aluminum extrusion and formed sheet stiffeners is proposed, which uses scrap ACM/MCM to make the shape to avoid the significant amount of waste associated with metal panel fabrication and assembly. Stiffeners are required for any panel which doesn't meet the deflection requirements for facade materials. Because staples are used as the fastening mechanism for these ACM/MCM stiffeners, they wilt seat against the ACM/MCM in elevation below the thickness of the double sided VHB tape which will attach the stiffener to the back of the panel. The ACM/MCM/sheet metal stiffener is made in the shape of a triangle because it is the strongest shape known, and even though some of the material may be routed away to make the bends, the performance of the shape is somewhat contingent on the fact that the bend locations will contact each other to help strengthen these areas as much as possible.
It may be apparent that novel and useful Solar Mounting Solutions have been hereinabove described which work and are used in a manner not consistent with conventional products and methods.
It is therefore an object of the present solar mounting application to provide a lightweight, strong, durable, inexpensive, and seismic rated solar panel mounting system with the best thermal efficiency which can be used on any structure, but particularly on the sides of buildings, or Building Integrated Photovoltaics (BIPV).
Another object of the solar mounting system is to support hardware with structural hardware struts for materials such as conductors, conduits, pipes, and equipment such as microinverters outside of the exterior insulation and without contacting or penetrating the weather barrier, and where the hardware struts may be coated with an insulation material to help prevent electrical and thermal conductivity as well as to help reduce vibration for noise reduction. The hardware struts may be hollow to save on materials, as well as to act as a heat sink to pull heat away from devices such as microinverters.
Another object of the solar mounting system is to structurally support more than one type of hardware, such as conductors, where each conductor is individually captured in a specific wire “harness” to allow for very clean and organized conductor circuitry.
Another object of the solar mounting system is to provide an anti-reflective lens which adds to the Power Conversion Efficiency instead of taking away from it by using a circuitous path for light to be directed towards the solar collectors.
Another object of the solar mounting system is to support solar panels using fully hardened stainless steel spring wires for attachment into any panel holes, slots, or shapes which the panels are made, including new thin film and flexible film solar module options, and where the solar panel mounting clips may have an included shape for a reveal strip to be inserted into, whether the reveal strip is architectural or structural.
Another object of the solar mounting system is the invention of a replacement reveal which allows a solar panel to be structurally mounted to a building through holes in the middle of the replacement reveal, and then then the holes are covered or inserted into with covers which are adhered to the reveal strip to provide a uniform appearance.
Another object of the solar mounting system is to stabilize sub-girts with one or more elongated high-tensile strength straps, wires or formed shapes which can be mounted through holes in the sub-girts, onto the sub-girts, or both, and fastened together with the sub-girt for more twist resistance of the sub-girt and to provide a more uniform load on the fasteners of the thermal clips supporting the sub-girts to the wall substrate.
Another object of the solar mounting system is to provide a cooler/heat sink which works as an independent and added component to microinverters, or which may be manufactured as part of the microinverter and shaped to match to prevent the microinverter from directly contacting insulation, panels and other materials which would prevent air-cooling of the microinverters.
Another object of the solar mounting system is to mechanically attach solar panels to buildings without fastening the solar panel mounting clips to the solar panel itself, where the solar mounting clips attach into or onto parts of the panel and permanently hold the panel in a fixed position once the solar panel mounting clips are fastened to the substrate.
Another object of the solar mounting system is to support the dead load of a solar panel from the top only, and then to attach the bottom of the adjacent solar panel above into the same solar panel attachment clip without any fastening at all so that installation of the panels is very fast and economical to do in the field.
Another object of the solar mounting system is to provide specialized washers, or support plates, which have at least one mounting hole with anti-reversal serrations for fasteners and at least one locating protrusion which helps prevent rotation when the fastener is being installed. The protrusion of course can be replaced with another fastener if desired. The support plate has at least one hemmed side which helps to support a reveal strip, and the shape of the support plate allows for structural support to prevent the formed solar panel attachment clip from moving in any direction, and specifically outwards when the panel system is introduced to dynamic negative wind loads.
Another object of the solar mounting system is to support panel loads using the benefits of a structural reveal strip which is mechanically attached to the solar panel frame thereby becoming part of the solar panel frame and increasing its overall load capacity during dynamic positive and negative wind load conditions due to its “ply-metal” added strengths, especially when tying perpendicular panel flanges together to increase the overall strength of the panel by distributing tensile and bend loads more evenly to more sides of a panel.
Another object of the solar mounting system is to use stainless steel staples to connect more than one piece of ACM/MCM or aluminum (or other metal which a staple can penetrate through) together permanently.
