Definitions

  • the invention is directed to a solar panel assembly and a method for preparing thereof.
  • Solar panels arranged on rooftops and on the ground in fields have unique requirements in that they must maintain the integrity under conditions of high humidity, because they are often positioned outdoors and exposed to rain, freezing rain, and snow and under conditions of widely varying temperature extremes, because they are often positioned in hot deserts, on hot asphalt rooftops, and in climates that experience extremely high temperatures, extremely low temperatures, and strong winds.
  • any mechanism used to secure and maintain solar panels in a fixed position must function under a difficult set of environment conditions.
  • a solar panel has usually a planar, rectangular configuration and comprises a light receiving surface and a non-light receiving surface.
  • the thin film solar panel generally requires the attachment of some means of fixing the panel to a substructure and elements which reinforce the panel. Typically these functions are combined by attaching a backrail.
  • Conventional crystalline silica cell based panels are typically framed both for stabilization and mechanical attachment to a substructure. Both types of panels can benefit from the present invention.
  • solar panel and support member are assembled by means of flexible glue or a double-sided tape, see for example WO 2009/102772 A2.
  • the invention features a solar panel assembly including a solar panel having a non-light receiving surface and a support member.
  • the support member is attached to the non-light receiving surface of the solar panel through both a handling adhesive and a structural adhesive.
  • the invention relates to a method for preparing a solar panel assembly. The method includes applying a handling adhesive and a structural adhesive onto a non-light receiving surface of a solar panel and/or a support member, and assembling the non-light receiving surface of the solar panel and the support member.
  • Figure 1 is a schematic cross-sectional view of an inventive solar panel assembly.
  • Figure 2 is a top view of a backrail as a support member for preparing an inventive solar panel assembly.
  • the solar panel assembly of the invention includes a solar panel having a non-light receiving surface and a support member.
  • the support member is attached to the non-light receiving surface of the solar panel through both a handling adhesive and a structural adhesive,
  • the term ''handling adhesive herein refers to an adhesive that facilitates assembly of a support member and a solar panel, e.g., offering a resistance to compression while a structural adhesive is curing.
  • structural adhesive herein refers to any adhesive that, upon final cure, provides a solar panel assembly with sufficient structural durability regarding the attachment of the support member and the solar panel. In other words, handling adhesive and structural adhesive are two different materials or compositions.
  • the handling adhesive is a hot melt composition and the structural adhesive is a curable composition.
  • hot melt composition When a hot melt composition is utilized as the handling adhesive, such hot melt composition is to be applied at higher temperatures, e.g., at least about 65°C or higher whereas the curable composition as the structural adhesive is normally applied at ambient temperature.
  • Suitable hot melt compositions as a handling adhesive include those that will provide enough green strength to allow initial handling of the solar panel.
  • Suitable curable compositions as a structural adhesive include those that will provide ultimate strong, durable adhesive bond that will stand for a long period of time under the environment conditions that a solar panel will experience.
  • suitable hot melt compositions as a handling adhesive in- elude thermoplastic material based hot melt compositions that are non-reactive hot melt compositions.
  • hot melt compositions suitable as handling adhesives also include reactive hot melt compositions.
  • a reactive hot melt composition is any thermoplastic adhesive or sealant that can be applied at elevated temperatures as liquid or semi liquid melt, cools to become solid at room temperature, and then subsequently reacts to become a thermosetting polymer with enhanced physical properties. Due to their thermoplastic nature during application but before curing, reactive hot melt compositions have many of the desirable processing characteristics of conventional hot melts, such as no solvents present, no mixing requirements, and immediate green strength.
  • suitable reactive hot melt compositions as a handling adhesive include hot melt moisture curable compositions. In other embodiments, suitable reactive hot melt compositions as a handling adhesive include other reactive hot melt compositions that are not moisture curable systems.
  • suitable non-reactive hot melt compositions as a handling adhesive include e.g., hot melt adhesives based on butyl rubber, or ethylene polyvinyl acetate (EVA), or amorphous poly-alpha olefin (APAO), with additives e.g., tackifying resin, wax, filler, and/or other materials known in the formulating art.

  • additives e.g., tackifying resin, wax, filler, and/or other materials known in the formulating art.
  • a hot melt moisture curable composition is used as a handling adhesive.
  • the hot melt moisture curable composition is a one-part thermoplastic moisture cure polyurethane composition that includes a) a polyurethane prepolymer component including the reaction product of at least one isocyanate compound and at least one amorphous polyester polyol which is formed from a diol and a diacid; and b) at least one theiTnoplastic rubber component.
  • the diacid has a chain length of greater than about 10 carbon atoms.
  • a hot melt moisture curable composition is used as a handling adhesive.

Further information regarding the hot melt moisture curable composition can be found in US 2004/0180154, incorporated by reference in its entirety.
