The present invention relates generally to solar arrays, and more specifically, to an articulating roof mount for solar arrays.
The solar industry is at the forefront of today's sustainability movement. Companies are spending a substantial amount of money outfitting their facilities with as many solar panels as possible, both to save cost and to reduce carbon footprint. The problem for many of these facilities is that roof functionality and accessibility takes precedence over the number of solar panels that can be used on a roof. Today, a large percentage of industrial roof space is set aside for maintenance accessibility needs, such as HVAC component access, fire protection/fighting needs, and common walkways. Currently, solar panels are not permitted in these areas.
The International Fire Code (IFC) imposes certain requirements on physical setbacks and space requirements which have significant impact on the potential placement of solar arrays. For example, the IFC mandates a six (6) foot setback around the entire perimeter of the roof, as well as a four (4) foot wide pathway around each roof hatch, and that space must be connected to the perimeter path of the roof by the addition of another four (4) foot wide pathway. These IFC-specified setbacks, along with maintenance access space, consume a large part of the roof real estate that could otherwise be filled with solar panels. An exemplary roof surface including an array of solar panels positioned surrounding a roof hatch in accordance with IFC setback mandates is shown in
Therefore, a need exists for a means to maximize usage of these code-mandated spaces, which go unused in the vast majority of instances, and in particular, a need exists for a means for utilization of the otherwise unused space for placement of solar arrays while still complying with IFC and other building code requirements.
Bearing in mind the problems and deficiencies of the prior art, it is therefore an object of the present invention to provide a means to maximize the number of solar panels which can be positioned on an existing roof structure while preserving maintenance accessibility needs.
It is another object of the present invention to provide a roof mount for a solar array which allows for utilization of otherwise unusable code-mandated roof spacing.
A further object of the invention is to provide an articulating roof mount for a solar array which permits walkway access to comply with existing building and fire code requirements for setbacks and spacing.
Still a further object of the invention is to provide an articulating roof mount for a solar array which permits access to the underside of the solar array for inspection, maintenance, and repair or replacement of components, without the need to remove the solar panel from the mounting assembly.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.
The above and other objects, which will be apparent to those skilled in the art, are achieved in the present invention which is directed, in one aspect, to an articulating solar panel mount assembly comprising a lower frame mountable to an installation surface and an upper frame for mechanically coupling to at least one solar panel and attached to the lower frame at a proximal end of the lower frame, wherein the upper frame is pivotable with respect to the lower frame between closed and open positions. In an embodiment, at least one hinge may be positioned on or proximate to a top surface of a cross-member of the lower frame to pivotally attach the upper frame to the lower frame. In at least one embodiment, a biasing mechanism such as a gas spring or strut is secured to the lower frame at a first end and to the upper frame at a second end, and is positioned to normally bias the distal end of the upper frame away from the lower frame toward the open position. A releasable latch mechanism is positioned to latch the upper frame to the lower frame in the closed position, wherein the latch mechanism includes a latch portion mounted for movement between a latch engaging position and a latch releasing position, and a trigger. Actuation of the trigger causes the latch portion to move from the latch engaging position to the latch releasing position to permit the upper frame to pivot to the open position as a result of a biasing force generated by the biasing mechanism.
In one or more embodiments, the latch mechanism may include a pin integral with or connected to the lower frame and offset from a top surface of the lower frame and extending in a direction approximately normal thereto, and the latch portion may be positioned proximate the distal end of an adjacent portion of the upper frame, wherein when the upper frame is in the closed position, the latch portion is releasably engaged with the pin.
The latch mechanism trigger may be a pull cord attached one at one end to the latch portion for moving the latch portion from the latch engaging position to the latch releasing position when tension is applied to the pull cord. In one embodiment, the pull cord extends through a plurality of spaced mounting clips along the length of a portion of the upper frame. In another embodiment, the pull cord may be at least partially embedded within a channel extending along the length of at least a portion of the upper frame.
The articulating solar panel mount assembly may further comprise at least one mounting bracket for attaching a solar panel to the upper frame, the mounting bracket comprising prongs at or proximate one end thereof for coupling to an outer edge of the solar panel and at least one mounting hole proximate an opposite end for receiving a fastener therethrough to secure the mounting bracket to one of the legs of the upper frame.
In an embodiment, the articulating solar panel mount assembly may further comprise a stop member integral with or coupled to the at least one hinge to prevent over-rotation of the upper frame during articulation to the open position. The stop member may have a fin projecting outwardly therefrom and having an angled surface presenting in a generally upward direction.
The upper frame may have longitudinal sides and lateral sides shorter than the longitudinal sides, and in one embodiment, the upper frame is pivotally attached to the lower frame about one of the longitudinal sides. In another embodiment, the upper frame is pivotally attached to the lower frame about one of the lateral sides.
In another aspect, the present invention is directed to a method of mounting a solar panel to an installation surface. The method comprises providing a solar panel mount assembly comprising a lower frame secured to the installation surface and an upper frame attached to the lower frame at a proximal end of the lower frame, wherein the upper frame is pivotable with respect to the lower frame between closed and open positions; a biasing mechanism secured to the lower frame at a first end and secured to the upper frame at a second end, the biasing mechanism positioned to normally bias the distal end of the upper frame away from the lower frame toward the open position; a releasable latch mechanism positioned to latch the upper frame to the lower frame in the closed position, the latch mechanism including a latch portion mounted for movement between a latch engaging position and a latch releasing position, and a trigger; and at least one solar panel secured to the upper frame. The method further comprises actuating the trigger to cause the latch portion to move from the latch engaging position to the latch releasing position; and pivoting the upper frame and the at least one solar panel to the open position as a result of a biasing force generated by the biasing mechanism.

Upper frame 20 generally comprises a boundary having substantially the same dimensions as the solar panel or solar array to be attached thereto. In the embodiment shown, the upper frame comprises a pair of substantially parallel legs 21a, 21b extending from a cross-member 25 disposed at a proximal end thereof, and a transverse member 24 disposed between and securing legs 21a, 21b at or proximate to a distal end thereof. As shown in the Figures, rectangular solar panels are depicted and therefore upper frame 20 is also generally rectangular, having opposing longitudinal sides and lateral sides with approximately the same length as the longitudinal and lateral sides of the solar panel; however, it should be understood by those skilled in the art that the present invention is not limited to a rectangular configuration and may be adapted to fit solar panels having non-rectangular shapes. In at least one embodiment, upper frame 20 may be comprised of 2×2 AL tubing and may be hinged/folded to allow for compact shipping and assembly (

In one or more embodiments, the mount of the present invention may further include a stop member 70 attached to the topside of hinge 14 to prevent over-rotation of the upper frame member and solar array during articulation of the mount. As shown in
Typical commercial roof set back requirements for solar panel arrays reduce a roof's solar capacity in some cases up to 30%. It is anticipated that solar arrays utilizing the articulating mount of the present invention will be able to boast more efficiency and more savings without sacrificing any building functionality. Moreover, the ability to tie in to existing fire protection systems will ensure seamless functionality for all fire protection measures.
In at least one embodiment, the solar panel mount 100 or 100′ of the present invention may be used as a safety railing at the edge of the roof line. Current solar arrays require a four (4) foot setback from the roof edge for walkway access. As shown in
It should be understood by those skilled in the art that the articulating mount of the present invention is not limited to use only adjacent roof hatches and other code-mandated walkways, and that installation across a broader surface area, or even the entire surface area, of the roof has further advantages. For example, the articulating mount of the present invention allows for simplified inspection and maintenance of the solar arrays themselves. Most or all conventional solar panels or solar arrays include components referred to as optimizers that are installed and usually zip-tied to the underside of the panel. In order to inspect the optimizer on conventional solar panel mounts, the panel must be removed from the mounting assembly. By contrast, utilization of the articulating mount of the present invention would not require removal of the solar panel to inspect the optimizer or other components of the solar array. Instead, the releasable latch mechanism allows the mount and solar panel attached thereto to be pivoted to the open position, permitting access to the underside of the panel for inspection and simplified repair or replacement of certain components if necessary.
Thus, the present invention provides one or more of the following advantages: The articulating solar panel mount provides a means to maximize the number of solar panels which can be positioned on an existing roof structure while preserving maintenance accessibility needs. Moreover, the articulating solar panel mount of the present invention allows for utilization of otherwise unusable roof spacing, and permits walkway access to comply with existing building and fire code requirements for setbacks and spacing. Further, the articulating solar panel mount permits easy access to the underside of the solar panel when in the open position, allowing for simplified inspection, maintenance and repair or replacement of components of the panel.
While the present invention has been particularly described, in conjunction with one or more specific embodiments, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
