1. Technical Field
The present technology relates to containment systems for solar energy panels.
2. Introduction
Solar energy panels are becoming an increasingly popular method to provide electrical and thermal energy to society. In many instances, the solar energy panels are installed at some distance or some angle relative to an installation surface, creating an open area between the solar energy panel and the installation surface, such as a rooftop, the ground, a foundation, or the like. In many areas, it is desirable or necessary to close off this vacant space in order to prevent airflow from pushing upwards on the solar energy panels, to prevent the spread of flames to the underside of a solar energy panel during a fire incident, to shade wires or electrical equipment from ultraviolet light, or to improve aesthetics. The present system to accomplish these goals includes installing a pane of metal or plastic around the open space after the solar energy panels have been installed on the installation surface.
The disclosed technology involves solar energy panel assemblies. Embodiments of the disclosed technology involve both framed and frameless solar energy panel assemblies. The solar energy panel assemblies can involve a photovoltaic panel mounted lateral edges or support beams that support the photovoltaic panel and extend substantially the length of the photovoltaic panel. The solar energy panel assemblies can also include hinge brackets that are coupled with the ends of the lateral edges and support beams and that rotate up and down to put the photovoltaic panel in an installation position at an angle relative to an installation surface and alternatively in a collapsed position for storing and transportation.
When the solar energy panel assemblies are in an installed position, an opening is created between the lateral edges/support beams and the installation surface. So, a containment shield is coupled with hinge brackets or photovoltaic panel to cover the opening. Likewise, a side cover containment shields cover the side opening between the lateral edges/support beams and the installation surface.
The containment shield can be rotatably coupled to the hinge brackets such that the containment shield can be opened and closed thereby exposing the opening made between the lateral edges/support beams and the installation surface.
In some embodiments of the present technology, the hinge brackets and containment shield are configured such that their combined thickness, when rotated in a position that is substantially parallel with the lateral edges/support beams, is less thick than the lateral edges/support beams themselves, thereby preventing the hinge brackets and containment shield from extending outside of the profile made by lateral edges/support beams and allowing the solar energy panel assemblies to be stackable for transport, storage, etc.
The solar energy panel assemblies can also include an electronics module (e.g. an electrical junction box) coupled with the photovoltaic panel that is substantially covered by the containment shield when the hinge brackets are rotated to be substantially parallel with the lateral edges/support beams. The containment shield can also include an attachment point for holding one or more accessories (e.g. a micro-inverter, DC optimizer, etc) for operating the photovoltaic panel.
In order to describe the manner in which the above-recited and other advantages and features of the disclosure can be obtained, a more particular description of the principles briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only exemplary embodiments of the disclosure and are not therefore to be considered to be limiting of its scope, the principles herein are described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the disclosure.
The solar energy panel assembly 100 can also include hinge brackets 103a and 103b, and a collapsible containment shield 102. The hinge brackets 103a, 103b can be rotatably coupled to the support beams 104a and 104b with a bolt, screw, rivet, pin, etc. and the hinge brackets 103a, 103b can rotate between positions that are substantially perpendicular to the support beams 104a and 104b and to positions that are substantially parallel with the support beams 104a and 104b. In some embodiments, the hinge brackets 103a, 103b can rotate into a position that is between the support beams 104a and 104b and substantially co-planar with the support beams 104a and 104b. Additionally, the hinge brackets 103a, 103b can be as thick or less thick than the support beams 104a and 104b so that the hinge brackets 103a, 103b do not extend away from the solar panel farther than the support beams 104a and 104b, thereby allowing a stack of solar energy panel assemblies to remain flat during shipping, storage, in the field, etc.
The solar energy panel assembly 100 shown in
In some embodiments, the support beams 104a and 104b and the hinge braces 105a, 105b can be configured to substantially lock the hinge brackets 103a, 103b from articulating when the hinge brackets 103a, 103b are rotated in certain positions.
For example,
Referring again to
The containment shield 102 can be a formed piece of flat metal, such as sheet metal, or made from a fiberglass, a plastic material, combinations of metal, fiberglass, and plastic, etc. A metal construction can provide increased strength and low manufacturing costs while a fiberglass or plastic material allows for complex shapes to be molded in the manufacturing process, such as tabs, hooks, flanges, screw holes, or perforations. Additionally, the fiberglass or plastic material acts as an electrical insulator, preventing the need for grounding or bonding the containment shield to an electric ground source.
The containment shield may have flanges protruding substantially orthogonal to the main surface to allow for the connection to the solar energy panel, or connection to one or more articulating beams. Additionally, the containment shield may have hemmed edges, rounded edges, or tabs on one or more perimeter edges to prevent a sharp edge from being exposed to nearby wires, electronics, and for easy handling.
The containment shield 102 reduces airflow under the solar energy panel 101 and, thereby, reduces the spread of flame under the solar energy panel assembly 101 in the case of a fire. The containment shield 102 can also protect wiring, inverters, etc. (not shown) coupled to or housed under the solar energy panel assembly 100 as well as the roof membrane (e.g. a water barrier that may be compromised when a solar energy panel is installed) and any other solar system or building components. In addition, the containment shield 102 improves the structural rigidity of the solar energy panel assembly 100.
In some embodiments, the containment shield 102 is connected to solar energy panel 101 using one or more of the hinge brackets 103a, 103b where the one side of a hinge bracket is welded, glued, riveted, or fastened to a containment shield, and the other side of a hinge bracket is welded glued, riveted, or fastened to a solar energy panel 101 or a solar energy panel's exterior frame. Additionally, the hinge interface may be formed into the containment shield 102 itself, and the opposite hinge component may be glued, welded, adhered, riveted, or similarly fastened to solar energy panel 101. The containment shield 102 may be the same width of solar energy panel 101, or may be of a greater or lesser width of the solar energy panel 101. The containment shield 102 can have a substantially similar width in order to maintain a substantially contained volume under one or more solar energy panels 101 when multiple solar energy panels are disposed next to one another. The edges of containment shield 102 may be straight, or may have a formed edge or hem to increase the stiffness, reduce sharp edges, and improve the handling ability during assembly and use.
Referring to
In some embodiments of the present technology, the containment shield 102 is rotatably coupled with the hinge brackets 103a, 103b to allow the containment shield 102 to be moved after the solar energy panel is installed on an installation surface to allow an operator access to the underside of the solar energy panel 101. For example, in some embodiments, the top-side fasteners at locations 106a, 106b can be removable such that a set of lower fasteners can be an axis of rotation for the containment shield 102.
Additionally, the containment shield 102 can be configured to rotate with the hinge brackets 103a, 103b, e.g. via rotating about the top-side fastener at locations 106a, 106b. As explained above, the hinge brackets 103a, 103b can be collapsible and can be as thick or less thick as the support beams 104a, 104b of such that, when in a collapsed position, the hinge brackets 103a, 103b are substantially parallel with the support beams 104a, 104b of the solar energy panel assembly 100 and the hinge brackets 103a, 103b do not extend away from the solar panel farther than the support beams 104a and 104b. Likewise, the containment shield 102 can also be substantially flat and can maintain the substantially parallel orientation the collapsed solar energy panel assembly 100. Furthermore, the containment shield 102 can be configured with a thickness that, together with the thickness of the hinge brackets 103a, 103b, does not extend away from the solar panel farther than the support beams 104a and 104b, thereby allowing a stack of solar energy panel assemblies to remain flat during shipping, storage, in the field, etc.
This collapsible, substantially planar orientation of the present technology has several advantages over existing art. First, the present technology provides the ability to reduce the area occupied by the solar energy panel 101 with the containment shield 102 installed when the hinge brackets 103a, 103b and the containment shield 102 are collapsed to be substantially parallel with the solar energy panel 101. The present technology also enables the containment shield 102 to be installed at a factory, warehouse, staging area, or the like, and occupy substantially the same or minimally greater volume during shipping, storage, transportation, etc. as compared to a solar energy panel assembly with no containment shield installed. Also, installing the containment shield 102 at a factory, warehouse, staging area, or the like, provides advantages in labor savings, material savings, quality improvement, and time savings during final installation of the solar energy panel assembly 100 on an installation surface.
The containment shield 102 can also include attachment points for accessories, (including accessories for securing wiring from the solar energy panel), pipes, inverters, micro-inverters, DC optimizers, batteries, electrical charging device, weather monitoring, or any other useful accessories. In some embodiments, accessories having a low profile can be installed on the face of the containment shield 102 facing the solar energy panel 101 and remain in position when the containment shield 102 is collapsed to be substantially parallel with the solar energy panel 101. This technology enables the accessories to be installed with the containment shield 102 and solar energy panel 101 at a factory, warehouse, staging area, or the like, and occupy substantially the same or minimally greater volume during shipping, storage, transportation, etc. as compared to a solar energy panel with no accessories nor containment shield installed. Installing the accessories at a factory, warehouse, staging area, or the like, provides advantages in labor savings, material savings, quality improvement, and time savings during final installation of the solar energy panel 101 on an installation surface.
As explained above, a containment shield can reduce airflow under the solar energy panel, can protect other components under the solar energy panel, can improve the structural rigidity of the solar energy panel assembly, etc. In some embodiments, the solar energy panel assembly also includes a side containment shield for further closing the underside of the assembly.
Some embodiments of the present technology also involve collapsible, framed solar panel assemblies.
The solar energy panel assembly 400 can also include hinge brackets 403a and 403b, and a collapsible containment shield 402.
As shown in
The solar energy panel assembly 400 shown in
Also, the solar energy panel assembly 400 includes a containment shield 402 coupled with the hinge brackets 403a, 403b to cover the opening made between the solar energy panel 401 and the installation surface when the hinge brackets 403a, 403b are rotated into a supporting position.
The containment shield 402 reduces airflow under the solar energy panel 401 and, thereby, reduces the spread of flame under the solar energy panel assembly 101 in the case of a fire. The containment shield 102 can also protect wiring, inverters, etc. (not shown) coupled to or housed under the solar energy panel assembly 100 as well as the roof membrane (e.g. a water barrier that may be compromised when a solar energy panel is installed) and any other solar system or building components. In addition, the containment shield 102 improves the structural rigidity of the solar energy panel assembly 100.
In some embodiments of the present technology, the containment shield 402 is rotatably coupled with the hinge brackets 403a, 403b to allow the containment shield 402 to be moved in the field to allow an operator access to the underside of the solar energy panel 401. Additionally, the containment shield 402 can be configured to rotate with the hinge brackets 403a, 403b. The containment shield 402 can also be substantially flat can be configured with a thickness that, together with the thickness of the hinge brackets 403a, 403b, does not extend away from the solar panel farther than the support beams 404a and 404b, thereby allowing a stack of solar energy panel assemblies to remain flat during shipping, storage, in the field, etc.
