Solar panel mounting configuration
Mounting clamps may be utilized to quickly and easily secure solar panel modules relative to mounting rails, which may in turn be secured relative to a mounting surface (e.g., a roof). The mounting clamps may be configured to quickly secure the solar pane modules relative to the mounting rails by tightening a tightening element to pull a clamp element toward the surface of a mounting rail, thereby clamping a portion (e.g., a frame) of a solar panel module between the clamping element and an outer surface of the mounting rail.
1 . A mounting system comprising:
a mounting rail having an interior and comprising:
flanges positioned at a top portion of the mounting rail and defining a rail channel along a length of the mounting rail;
a rail splice configured for being positioned partially within the interior of the mounting rail, the rail splice comprising:
a bottom wall and sidewalls collectively defining an exterior surface of the rail splice; and
a key feature on the exterior surface of the rail splice, the key feature defining a first rail splice portion along a length of the rail splice and a second rail splice portion along the length of the rail splice, wherein the key feature is configured to engage an end of the mounting rail when either the first rail splice portion or the second rail splice portion is positioned within the interior of the mounting rail; and
a mounting clamp for securing one or more modules to the mounting rail, the mounting clamp comprising:
a clamp component defining a horizontal clamp surface; and
a channel nut configured for being positioned within the interior of the mounting rail, the channel nut comprising:
a top channel nut portion configured to fit within the rail channel at the top portion of the mounting rail when the channel nut is positioned within the interior of the mounting rail; and
a bottom channel nut portion configured for being positioned below the flanges of the mounting rail and between the sidewalls of the rail splice when the channel nut is positioned within the interior of the mounting rail such that the bottom channel nut portion is spaced from the sidewalls of the rail splice.
2 . The mounting system of claim 1 , wherein the key feature of the rail splice is centered along the length of the rail splice.
3 . The mounting system of claim 1 , wherein the sidewalls of the rail splice are biased to impart a compressive force onto the mounting rail to secure the rail splice to the mounting rail when the rail splice is positioned within the interior of the mounting rail.
4 . The mounting system of claim 1 , wherein the sidewalls of the rail splice are configured to engage the flanges positioned at the top portion of the mounting rail when the rail splice is positioned within the interior of the mounting rail.
5 . The mounting system of claim 1 , wherein the channel nut is configured to engage the flanges positioned at the top portion of the mounting rail when the channel nut is positioned within the interior of the mounting rail.
6 . The mounting system of claim 1 , wherein the one or more modules comprise at least a solar panel.
7 . The mounting system of claim 6 , wherein the clamp component is configured to engage a panel top surface of the solar panel.
8 . The mounting system of claim 1 , further comprising:
a fastening member adjustably securing the clamp component to the channel nut, the fastening member having an adjustment head extending above a clamp top surface of the clamp component, wherein the fastening member is configured to, when tightened by rotating the adjustment head, move the clamp component toward the channel nut.
9 . The mounting system of claim 8 , wherein the mounting clamp further comprises:
a compressible resilient member positioned between the clamp component and the channel nut, wherein the compressible resilient member is configured to support the clamp component a distance away from the channel nut.
10 . The mounting system of claim 9 , wherein the compressible resilient member comprises a metal material.
11 . The mounting system of claim 9 , wherein the compressible resilient member comprises:
one or more side members, each of the one or more side members having a height measured between a base of the compressible resilient member and a top end of the respective side member of the one or more side members, and each side member of the compressible resilient member defines a vertical arm portion that, when compressed, forms substantially stacked sheet portions.
12 . The mounting system of claim 11 , wherein the compressible resilient member further comprises:
a compressible resilient member aperture configured to receive at least a portion of the fastening member therein, wherein the compressible resilient member aperture is defined at least in part by an outer perimeter that at least partially surrounds the at least a portion of the fastening member.
13 . The mounting system of claim 11 , wherein the channel nut engages the rail channel when the channel nut is positioned within the interior of the mounting rail.
