  • the invention pertains generally to a mechanical device and method for attaching solar panels (that is, photovoltaic panels), or a series of panels, to the surface of a roof.
  • this invention pertains to apparatus and methods for attaching thin film and framed solar panels in a way that can be readily installed on and removed from a variety of different type roof surfaces, is durable, lightweight, accommodates the various weather conditions encountered by such systems, including the differing coefficients of thermal expansion between whatever the roof material upon which the panels are installed and the panels themselves, is attractive, and is cost effective.
  • a popular solar-powered, electrical generation device is the photovoltaic system that converts light into electricity.
  • the basic light-to-electricity phenomenon (sometimes referred to as the photovoltaic or PV effect) was first discovered in 1839. But it took nearly another century before scientists truly understood this process, and it was discovered that the conversion process occurs at the atomic level. During that time, many renowned scientists became interested in the PV effect. Even Albert Einstein published a paper on it in 1905.
  • attachment systems that did not puncture the existing surface were preferred. Also, for significant tax reasons, having the system not be permanently attached to the roof of the structure was often preferred. Therefore, attachment systems in which the panels were removably secured on the roof top were developed.
  • ballast weight may need to be substantial because the solar panels, by definition, must cover a relatively large area in order to be effective. Therefore, they may be subjected to very high winds, and the ballast needs to keep the panels and support structure in place, otherwise they can become an airborne projectile that can cause damage to people and property.
  • the added costs, inconvenience and weight affiliated with these ballast-type systems created the need in the industry for a better apparatus and method to attach solar panels, and particularly thin film panels, to an existing roof system.
  • the solar panels can be exposed to wind gusts up to and even in excess of 100 mph. Earthquakes can also cause the solar panels to move if not adequately secured. Because of the risk of injury to property and to persons if the solar panels move, or worse, become airborne in the wind, require that whatever method and mechanism are used to secure the panels to the roof, they must be adequate to hold the panel in place even in extreme conditions. Given these concerns, it is not surprising that using hook-and-loop technology has not previously been used, and would not be an obvious choice to use, as the means and method to attach these panels to a roof.
  • a system for attaching solar panels is achieved which is lightweight (typically less than 1 pound per square foot of coverage) such that re-engineering of the existing roof system is not required; is low cost (requiring less time, personnel, hardware and equipment to install); provides for rapid electrical integration; requires no roof penetration; requires no ballast; presents no added roof obstacles beyond the panels themselves; is easily removable, if necessary, without damage to the roof system; can be applied not only to flat roof systems, but also to sloped and curved roof systems; can be easily configured to accommodate existing roof installations; and is aesthetically pleasing, among other advantages.
  • the present invention uses a hook-and-loop system as the attachment means to adhere the solar panels to the rooftop material, or to an intermediary structure.
  • This can be used with either the flexible thin film solar panels, or with framed solar panels.
  • This can be used to attach the framed panels directly to the roof surface, or to racks or other intermediate structures that are in turn attached to the roof.
  • the hook material can be attached using any suitable means such as adhesive along the edges of the underside of the flexible thin film solar panel, and the loop material can be attached directly to the top of the roofing systems, again using any suitable means, such as adhesive, in an area that coincides with the preferred arrangement of the panels on the roof, so that the hook and loop aspects properly align and mate upon installation.
  • the entire underside of the thin film solar panels can be fitted with either the hook or the loop material, and that the other portion can be strategically placed on the roof, thereby eliminating the need for the two portions to be exactly aligned before attachment.
  • the hook material being less expensive than the loop material, is attached to the underside of the panel, and the loop material is attached to the roof.
  • the hook material is thermally bonded directly to the underside of the panel during the construction of the panel, preferably a Uni-Solar PVL-136 Panel, so as to eliminate the need for an adhesive layer between the hook material and the underside of the panel.
  • the solar panels are first housed or adhered to steel, metal or plastic frame-like or rack-like substrate (which can have flat or corrugated underside, and then the substrates can be attached to the roof system using hook and loop.
  • the substrate is formed into customized channels or track into which the thin film panels are inserted, and then the track is attached using hook and loop material. In the preferred method, the amount of area required for hook and loop attachment is calculated to ensure that the panels, once attached, remain in place.
  • the panels can be attached in a way that is very cost effective, and does not add weight to the roofing system. Also, the hook and loop material will absorb some movement between the solar panels and the roof system which occurs dues to the differing coefficients of heat expansion between the two different materials. Therefore, the roofing system nor the panels will be subjected to damaging stress as the panel and the roof system are repeatedly cycled through the heat of the day and the cold of the night.
  • Figure 1 shows a typical attachment arrangement in which either the hook or the loop portion of a typical hook-and-loop two part attachment system is attached to the underside of the solar panel, whereas the other part of the hook-and-loop attachment system is attached directly to the upper surface of the roof. In this instance, the hook and the loop portions will interact to hold the solar panel directly to the roof.
  • Figure 2 shows an alternative attachment arrangement in which the solar panel is first attached to an intermediate device, such as a frame, and then either the hook or the loop portion of a typical hook-and-loop two part attachment system is attached to the underside of the frame, whereas the other part of the hook-and-loop attachment system is attached directly to the upper surface of the roof. In this instance, the hook and the loop portions will interact to hold the framed solar panel to the roof.
  • Figure 3 shows the presently preferred construct of the thin film solar panel to which the hook material is thermally bonded to the entirety of the underside of the solar panel.
  • Figure 4 shows in side view a schematic of the preferred mating of the solar panel, the hook material, the loop material and the upper surface of the roof system.
  • Figure 5 shows an alternative method for bonding the hook material to the underside of the panel using an intermediate double-sided adhesive.
  • Figure 6 shows a side view of one embodiment in which a thin film solar panel is attached to the roof wherein the entirety of the underside of the panel is fitted with the hook material, and strips of the loop material are attached to the roof system.
  • the loop material strips are first laid out and attached to the roof, and then the hook material on the underside of the panels is attached thereto. Because the entirety of the underside of the panel is fitted with the hook material, exact precision in aligning the hook material with the loop strips is not required. The amount of the loop material required per square area of panel is calculated using the method of this invention.
  • Figure 7 shows another embodiment in which the underside of the solar panel is completely fitted with a layer of double-sided adhesive to which the hook material is similarly attached, covering the entire underside of the panel.
  • the loop strips in an amount calculated as hereinafter described, are then attached to the edges of the panel's underside-covered hook material. Adhesive on the underside of the loop strips is then used to attach that assemblage to the roof system surface (or other intermediary structure or substrate).
  • Figure 8 shows yet another embodiment in which adjacent panels, which hook material attached, can be attached to one another in a sheet-like way, and then the entire sheet attached to the loop material attached to the roof system surface.
  • Figure 9 shows an alternative embodiment in which an array of framed solar panels are mechanically attached to brackets, which are in turn attached to the roof system surface using hook and loop material.
  • Figure 10 shows an alternative embodiment in which the framed solar panels can be directly attached to the roof system surface by placing strips of hook material to the frame edges, which then mate with loop material attached directly to the roof system surface.
  • Figure 1 1 shows an alternative embodiment where, due to the latitude of the building location, it is preferred that the panels not be installed flat on the roof system surface, but are at a slight angle so as to catch the sun's light more directly.
  • the framed solar panels can be attached to a simple intermediate structure that can be constructed of metal or plastic or other suitable material and that when attached to the roof system, presents the solar panel at the preferred angle relative to the sun.
  • the framed solar panel can be mechanically attached to the support structure by any suitable means, such as screws or bolts, for example, and the structure can be attached to the roof surface using hook and loop. Again, the amount of hook and loop material that must be used is calculated using the method hereinafter described.
  • Figure 12 shows another embodiment that can be utilized with a pre-framed panel, in which a I-Rail or similar intermediary structure is used, to which the frame of the panel is attached to the upper portion by mechanical means such as screws or bolts, and the lower end of the I-Rail is attached to the roof system surface using hook and loop. As shown here, both the hook and loop portions are attached using a double-sided adhesive.
  • Figure 13 shows another embodiment that can be utilized with a pre-framed panel that utilizes the same I-Rail or similar intermediary structure as in Figure 13, but in which an upper pair of metal and rubber washers are used with a single screw that does not puncture the panel frame.
  • Figure 14 shows an embodiment that can be utilized with the flexible panels and with the I-Rail or similar intermediary structure as in Figures 12 and 13, in which a metal plate is first attached to or lain on the upper surface of the I-Rail or block, and the flexible panels attached thereto by means of a clamping device, which is attached to the I-Rail by mechanical means such as screws or bolts, and the lower end of the I-rail is attached to the roof system surface using hook and loop. As shown here, both the hook and loop portions are attached using a double-sided adhesive.
  • Figure 15 is another embodiment by which the flexible panels can be attached to the underlying metal plate, and then the adjacent plates attached to a single I-Rail.
  • Figure 16 shows a top view of a grid lay-out in which the I-Rails are of relatively short length such that they appear to be square and are positioned only at the corners of each of the panels.
  • Figure 17 is another embodiment by which the flexible panels can be attached to an underlying metal plate, but in this instance the underlying metal plate resides on a corrugated substrate structure (shown in cross-section in this Figure).

  • Figure 19 shows a typical layout of a pair of thin film solar panels, depicting their relative length and width, as they would appear in a top view after they had been installed on the roof system structure by any of the embodiments shown above, except those using the I-Rail component.
  • the top view of those embodiments would appear substantially the same, except that the screws, clamps and washers used to attach the assemblage to the I-Rail would be visible, but only barely.

  • the orientation disclosed, however, is preferred in that hook material 14 is typically less expensive that loop material 16, and since in most application less material is applied to the roof system surface 20 that is applied to the panel 10, apply the hook material 14 to the panel 10 is a potential cost saving matter.
  • the preferred adhesive layers 12 and 18 for this embodiment is available from Sika Corporation, SikaLastomer®-68 ethylene propylene copolymer tape, as it has been found to have acceptable strength and durability, and compatibility with the material in the underside of the most commerically available flexible solar panels 10. It has also been found to be suitable for attachment to most roof system surfaces 20. Because, however, there are many different types of roof surface materials, any adhesive 18 must first be tested to confirm that it will properly adhere to and is compatible with the roof surface 20, but also care should be taken to ensure that application will not adversely affect any warranty that may then be extant for the roof system and/or surface.
  • the adhesive layer 18 is applied to the underside of the loop portion 16, and then that combination is applied directly to the roof surface 20. It is important, of course, to ensure that the roof surface 20 is free of contaminants or other material that would impede a good bond between the adhesive layer 18 and the surface 20. Utilizing thin film panels 10 provides a flexible, lightweight system that will find utility with most roof systems, and will be particularly useful and applicable in situations that involve curved or sloped roof systems, or where the existing roof system is not engineered to accommodate significant added weight, or where aesthetics of the roof after installation is a design criteria.

Also, application of the hook material 14 to the solar panel during or immediately after the manufacturing process will ensure a superior and more reliable attachment that will not be affected by conditions at the job site, or dependent upon the skill of the installer.

  • FIG 5 another embodiment is shown in which the panel 10 is attached to the hook material 14 by means of the intermediately adhesive tape 12. As shown here, even in this embodiment, it is preferred that the entire underside of the panel 10 be fitted with the hook material 14. This will provide a more durable adhesion between the two interfaces of panel-tape and tape-hook material as there will be greater surface area of attachement, and also fewer edge areas where initial separation can occur.
  • roof system surfaces 20 there are many different types of roof system surfaces 20 that may be encountered in the field. Some of the more typical surfaces to which solar panels may be attached using the means and methods discussed herein are white membrane, metal, PVC or foam.

Abstract

La présente invention concerne un appareil et un procédé pour fixer des panneaux solaires photovoltaïques à une surface de système de toiture. Des panneaux souples en couches minces sont fixés à l'aide d'un système de crochet et d'oeil dans lequel le matériau de crochet ou d'oeil est fixé à la face inférieure de panneau, et l'autre parmi le matériau de crochet et d'oeil est fixé au toit. Des panneaux solaires qui sont enserrés dans un cadre sont fixés à l'aide du matériau de crochet et d'oeil directement à la structure du système de toiture, ou à une structure intermédiaire, qui à son tour est fixée à la surface du système de toiture. Le procédé détermine également la quantité de matériau de crochet et d'oeil qui doit être fixée à chaque panneau installé pour assurer que les panneaux installés seront aptes à résister à l'effort d'arrachement de la pression du vent requis, et pour assurer que dans le cas d'un effort de d'arrachement imprévu et excessif l'effort de d'arrachement est toujours contré, les panneaux étant séparés au niveau de l'interface de crochet et de boucle.
