Solar panel racking system and devices for the same
A solar panel racking system that can include end clamps, mid clamps, bottom clamps, L-foot adapter assemblies, rails, and L-foot assemblies. The solar panel racking system minimizes the use of tools by snapping many of the mounting components in place. The end clamps, mid clamps, and bottom clamps can snap over the rail sides and lock into upper detented portions of the rail sides. The upper detented portions are structured to prevent upward movement of the end clamps, mid clamps, and bottom clamps. The L-foot adapter body of the L-foot adapter assembly snaps over lower detented portions of rail sides and secures the rail to an L-foot assembly. The end clamps, mid clamps, bottom clamps, rails, and L-foot adapter assemblies are independent of the L-foot assembly, allowing a selection of L-foot assemblies to be used as appropriate with the solar panel racking system.

6. The device of claim 1 , wherein:
the L-foot adapter assembly further comprises a threaded fastener that threadedly engages a side of opposing sides of the L-foot adapter body; and
the L-foot includes a slot, the slot in combination with the threaded fastener allows the L-foot adapter body to move up and down with respect to the mounting structure.
7. The device of claim 1 , wherein:
the L-foot adapter body includes a bottom and a first L-foot adapter side and a second L-foot adapter side projecting upward from the bottom;
a first clamping portion positioned on the first L-foot adapter side and a second clamping portion positioned on the second L-foot adapter side; and
the first clamping portion and the second clamping portion are sized and shaped to prevent upward movement of the rail once the rail is snapped or rotated into the L-foot adapter body.
8. The device of claim 7 , wherein:
the L-foot adapter body is a one-piece body;
the second L-foot adapter side that is cross-sectionally thicker and more rigid than the first L-foot adapter side; and
as the rail engages the first clamping portion and the second clamping portion, the first L-foot adapter side bends outward and the second L-foot adapter side remains stationary as rail is either snapped or rotated into place.
9. The device of claim 1 , wherein:
the L-foot adapter body is a one-piece body and comprises a bottom, a first L-foot adapter side and a second L-foot adapter side that extend upward from opposite ends of the bottom; and
the first L-foot adapter side is thinner and more flexible than the second L-foot adapter side.
10. The device of claim 9 , wherein:
the first L-foot adapter side includes a first serrated surface that faces outward; and
the L-foot engages against the first serrated surface.
11. The device of claim 1 , wherein:
the L-foot adapter body is a one-piece body, the L-foot adapter body comprises a bottom, a first L-foot adapter side and a second L-foot adapter side extending upward from the bottom;
the first L-foot adapter side engages the L-foot and is thinner and more flexible than the second L-foot adapter side;
the first L-foot adapter side bends outward while the second L-foot adapter side remains stationary as the rail is snapped or rotated into the L-foot adapter body; and
the first L-foot adapter side being tightened against the L-foot causes the first L-foot adapter side to become rigid.
12. A device for attaching a rail and a solar panel to a mounting structure, comprising:
an L-foot that is sized and shaped to attach to the mounting structure;
an L-foot adapter assembly comprising an L-foot adapter body;
the L-foot adapter body is a one-piece body and comprises a bottom, a first L-foot adapter side and a second L-foot adapter side extending upward from the bottom;
the first L-foot adapter side engages the L-foot and is thinner and more flexible than the second L-foot adapter side;
the first L-foot adapter side bends outward while the second L-foot adapter side remains stationary as the rail is snapped or rotated into the L-foot adapter body; and
the first L-foot adapter side being tightened against the L-foot, causes the first L-foot adapter side to become rigid.
13. The device of claim 12 , wherein:
the L-foot adapter assembly further includes a threaded fastener; and
the threaded fastener threadedly engages the second L-foot adapter side causing the first L-foot adapter side to tighten against the L-foot and become rigid.
14. The device of claim 12 , wherein:
the L-foot adapter assembly further comprises a threaded fastener that threadedly engages the second L-foot adapter side; and
the L-foot includes a slot, the slot in combination with the threaded fastener, when untightened allows the L-foot adapter body to move up and down with respect to the mounting structure and when tightened prevents movement of the L-foot adapter body with respect to the mounting structure.
15. The device of claim 12 , wherein:
the L-foot adapter body includes a first clamping portion positioned on the first L-foot adapter side and a second clamping portion positioned on the second L-foot adapter side; and
the first clamping portion and the second clamping portion are sized and shaped to prevent upward movement of the rail within the L-foot adapter body once the rail is snapped or rotated into the L-foot adapter body.
16. The device of claim 12 , wherein:
the first L-foot adapter side includes a first serrated surface that faces outward; and
the L-foot engages against the first serrated surface.
17. A device for attaching a rail and a solar panel to a mounting structure, comprising:
an L-foot adapter assembly comprising an L-foot adapter body that is sized and shaped to allow the rail to snap or rotate downward into the L-foot adapter body and be secured therewith;
an L-foot that is sized and shaped to attach to the mounting structure; and
the L-foot adapter assembly being engaged with the L-foot, the L-foot adapter body can extend upward or downward with respect to the L-foot independently of holding tension of the rail to the L-foot adapter body.
