This disclosure relates generally to modular, self-supporting mounting systems of solar modules, and in particular, modular self-supporting mounting devices for mounting solar modules on a flat roof.
As solar energy becomes more popular, so do new ways to attach solar panels (also called PV modules) to different surfaces, like rooftops or the ground. Over time, these systems have been improved to make them easier and faster to install. However, some challenges remain, especially when it comes to safety and efficiency. For example, many current systems are made up of lots of parts, which can make installation slow and tricky. This is particularly concerning when workers have to install panels in difficult or dangerous places, like on rooftops.
Solar panels are used to create electricity for homes and businesses. Since one panel can only produce a small amount of electricity, several panels are usually grouped together to form what's called a PV array. These arrays are often installed on rooftops or the ground and are positioned to face south (if installed in the Northern Hemisphere) so they get the most sunlight throughout the day.
Even though there are many systems available to secure solar panels, they often have significant downsides. Some systems are expensive to make or take a long time to install. Others might require custom parts to fit specific types of panels, which makes the process more complicated. Additionally, some systems can damage the roof they're attached to, especially if they puncture the roof's protective layer. Other designs take up too much space, reducing the efficiency of the panel array. In some cases, these systems also have issues with proper grounding, which is important for safety.
Because of these challenges, there's still a lot of room to create better mounting systems for solar panels-ones that are more affordable, easier to install, eco-friendly, and safer for both the workers and the surfaces they're mounted on.
Apparatuses are disclosed for use in a solar module array system. In certain examples, the apparatuses include a bracket having a base and at least two arms extending outward from the base at an angle with reference to the base, where an arm of the at least two arms is configured to couple with a solar module. Also included is a ballast device having an interior chamber configured to receive a flowable material, and where the ballast device has at least one surface feature configured to receive the bracket and secure the solar module to a mounting surface.
In certain examples, the solar module has a length and a width, and the ballast device has a length substantially equal to the length of the solar module. The ballast device, in certain examples, is disposed on the mounting surface and at least partially below a top surface of the solar module to form a wind break and limit wind penetration underneath the solar module.
In certain examples, the apparatuses include a second ballast device disposed along an opposite side of the solar module from the ballast device. The second ballast device is installed at an angle with respect to a vertical line to create downward force on the solar module when the second ballast device is impinged by wind. In certain examples, at least one arm of the at least two arms of the bracket comprises one or more barbs configured to lock the bracket into the at least one surface feature.
In certain examples, the at least one surface feature comprises a slot configured to receive at least one arm of the bracket. An end bracket is also included and has a base, an arm extending upward from the base, and an arm that is coplanar with the base, and where the end bracket is configured to couple with an anchoring device. The ballast device may include at least one opening for receiving the flowable material. In certain examples, the ballast device comprises an elongated rectangular shape.
A method of providing the apparatuses is also included.
In order that the advantages of the invention will be readily understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings, in which:
Reference throughout this specification to “one example,” “an example,” or similar language means that a particular feature, structure, or characteristic described in connection with the example is included in at least one example of the present disclosure. Appearances of the phrases “in one example,” “in an example,” and similar language throughout this specification may, but do not necessarily, all refer to the same example. Similarly, the use of the term “implementation” means an implementation having a particular feature, structure, or characteristic described in connection with one or more examples of the present disclosure, however, absent an express correlation to indicate otherwise, an implementation may be associated with one or more examples.
The ballast device 104 is formed, in certain examples, with a generally rectangular cross-sectional profile, as depicted. However, any suitable cross-sectional profile is contemplated. Beneficially, a substantially rectangular cross-sectional profile allows for the use of the ballast device 104 in a horizontal configuration (e.g., the left side ballast device 104) or a vertical configuration (e.g., the right side ballast device 104), without needing different sized ballast devices 104. Such different positioning options allows for the solar panel 106 to be installed on an angle, which, as is known to those skilled in the art, is helpful for maximizing photovoltaic energy production by angling the solar panel 106 towards the sun.
In certain examples, the bracket 102 is a press-fit bracket 102 that engages slots formed in the ballast device 104. The bracket 102 may have a generally H-shaped cross-sectional profile so that downwardly extending portions engage slots formed in the ballast device 104, as will be described in greater detail below. A bracket may also be used to couple and stack multiple ballast devices 104.
Beneficially, a ballast device 104 that has a length 114 that is substantially equivalent to the length 110 of the solar panel functions to stop wind from getting under the one or more solar panels 106 and lifting the solar panels 106 off the ground or other surface.
The ballast device 104, when configured as a tank, may be formed of any material suitable to hold a significant amount of water. In certain examples, the ballast device 104 is a tank formed of a high-density polyethylene. In other examples, the ballast device 104 is formed of metal or a metal alloy.
One or more slots 208 may be disposed on each side of the ballast device 104. Each of the slots 208 may extend along external surfaces of the lengthwise side 206. The one or more slots 208 are configured to receive a portion of the bracket 102. The slots may have a depth that extends toward a longitudinal axis a distance in the range of between about. 1 and 3 inches. In other examples, the depth of each slot is selectable according to a desired bracket size. In the example of a polymer-based ballast device, the slot 208 are configured to receive a barbed bracket that “bites” into the sides of the slots 208.
Beneficially, the positioning of the one or more slots 208 allows for the use of a bracket 102 that may couple together adjacent ballast devices 104 for the purpose of stacking the ballast devices 104. Such an H-shaped bracket is described below in greater detail. In alternative examples, a bracket that is I-shaped may be used to engage a single slot in each of the adjoining ballast devices 104.
Referring to
The base 306 and the lower arms 304 are configured to engage the slots of the ballast device 104. In certain examples, the lower arms 304 are configured with one or more barbs 308 that extend outward from the lower arms 304 and engage surface of a slot 208 and fix the bracket 102 with the ballast device 104. The barbs 308, in certain examples, are features that are punched in the surface of the lower arm 304. In other examples, an adhesive may be utilized to secure the position of the bracket 102 with respect to the ballast device 104. In yet other examples, the bracket 102 may be formed with five or more total arms, instead of the depicted four arms 302, 304. For example, a total of eight arms may be used. However, the depicted example is efficient from a manufacturing point of view, as the depicted bracket 102 may be formed by bending arms 302, 304 from a single piece of sheet metal.
In certain examples, the end bracket 400 has an arm 404 for inserting into a slot of the ballast device 104, and an arm 406 for coupling with a solar panel 106 or an anchoring device. In other examples, the end bracket 400 is provided with an opening 408 for receiving the pole 402. The arm 404 may have a portion that is coplanar with a base 410 of the end bracket 400. In certain examples, the second arm 406 is substantially perpendicular to the base 410.
In certain examples, the ballast device 500 is configured with integral ridges 504 extending outward from a surface of the ballast device 500 and configured to either couple with a solar panel 106 or with another ballast device 500. The ballast device 502 of
The handle 702 is sized slightly smaller than the width of the base bracket 700, thereby causing a clamping action on the ballast block, forming one structural bracket assembly. The optional handle 702 increases clamping forces and adds even more structural integrity to the base bracket 700, especially if no ballast block is utilized and the bracket 700 is glued or screwed directly to the roof's surface, the handle 702 boxes or closes off the brackets open end for better racking strength. The handle 702 when attached or bolted properly provides a clamping force on the two upright legs to help keep them vertical and well supported higher up on the base bracket 700. The disclosed base bracket 700 has a large flat bottom to prevent damage to the roofs surface under snow load or from ballast loads.
In the above description, certain terms may be used such as “up,” “down,” “upper,” “lower,” “horizontal,” “vertical,” “left,” “right,” “over,” “under” and the like. These terms are used, where applicable, to provide some clarity of description when dealing with relative relationships. But, these terms are not intended to imply absolute relationships, positions, and/or orientations. For example, with respect to an object, an “upper” surface can become a “lower” surface simply by turning the object over. Nevertheless, it is still the same object. Further, the terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise. Further, the term “plurality” can be defined as “at least two.”
Additionally, instances in this specification where one element is “coupled” to another element can include direct and indirect coupling. Direct coupling can be defined as one element coupled to and in some contact with another element. Indirect coupling can be defined as coupling between two elements not in direct contact with each other, but having one or more additional elements between the coupled elements. Further, as used herein, securing one element to another element can include direct securing and indirect securing. Additionally, as used herein, “adjacent” does not necessarily denote contact. For example, one element can be adjacent another element without being in contact with that element.
As used herein, the phrase “at least one of”, when used with a list of items, means different combinations of one or more of the listed items may be used and only one of the items in the list may be needed. The item may be a particular object, thing, or category. In other words, “at least one of” means any combination of items or number of items may be used from the list, but not all of the items in the list may be required. For example, “at least one of item A, item B, and item C” may mean item A; item A and item B; item B; item A, item B, and item C; or item B and item C. In some cases, “at least one of item A, item B, and item C” may mean, for example, without limitation, two of item A, one of item B, and ten of item C; four of item B and seven of item C; or some other suitable combination.
Unless otherwise indicated, the terms “first,” “second,” etc. are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, e.g., a “second” item does not require or preclude the existence of, e.g., a “first” or lower-numbered item, and/or, e.g., a “third” or higher-numbered item.
As used herein, a system, apparatus, structure, article, element, component, or hardware “configured to” perform a specified function is indeed capable of performing the specified function without any alteration, rather than merely having potential to perform the specified function after further modification. In other words, the system, apparatus, structure, article, element, component, or hardware “configured to” perform a specified function is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the specified function. As used herein, “configured to” denotes existing characteristics of a system, apparatus, structure, article, element, component, or hardware which enable the system, apparatus, structure, article, element, component, or hardware to perform the specified function without further modification. For purposes of this disclosure, a system, apparatus, structure, article, element, component, or hardware described as being “configured to” perform a particular function may additionally or alternatively be described as being “adapted to” and/or as being “operative to” perform that function.
The schematic flow chart diagrams included herein are generally set forth as logical flow chart diagrams. As such, the depicted order and labeled steps are indicative of one example of the presented method. Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more steps, or portions thereof, of the illustrated method. Additionally, the format and symbols employed are provided to explain the logical steps of the method and are understood not to limit the scope of the method. Although various arrow types and line types may be employed in the flow chart diagrams, they are understood not to limit the scope of the corresponding method. Indeed, some arrows or other connectors may be used to indicate only the logical flow of the method. For instance, an arrow may indicate a waiting or monitoring period of unspecified duration between enumerated steps of the depicted method. Additionally, the order in which a particular method occurs may or may not strictly adhere to the order of the corresponding steps shown.
The present subject matter may be embodied in other specific forms without departing from its spirit or essential characteristics. The described examples are to be considered in all respects only as illustrative and not restrictive. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
