Solar panel installation systems and methods
Solar panel installation systems are disclosed that reduce or eliminate the need for large, costly rails for mounting solar panels on an installation surface. The systems may include an array of framed solar modules supported above an installation surface using a number of height-adjustable base members. Adjacent solar modules in the array may be coupled to one another at or near their corners using module links that can structurally couple the frames of the adjacent solar modules together.
1. A height-adjustable base member, comprising:
an arm, comprising:
a first side and a second side, wherein the second side has a convex surface; and
a bore extending from the first side to the second side;
a lever, comprising:
a concave surface configured to engage with the arm in a first mode and a second mode, wherein in the first mode, the convex surface is engaged within the concave surface, and wherein in the second mode, the convex surface is disengaged from the concave surface; and
a bore extending through the convex surface along an axis of rotation of the lever; and
a fastener, inserted through the bores of the arm and the lever, coupling the arm to the lever.
2. The height-adjustable base member of claim 1 , further comprising:
a channel clamping member comprising a bore receiving the fastener, wherein the channel clamping member is pulled toward the first side in the second mode and pushed away from the first side in the first mode.
3. The height-adjustable base member of claim 2 , further comprising:
a captive spring arranged between the arm and the channel clamping member that bears against the channel clamping member to urge it away from the first side in the first mode.
4. The height-adjustable base member of claim 2 , wherein:
the channel clamping member comprises a bottom side arranged proximate to the first side and a top side arranged distal from the top side;
the bottom side comprises two flanges;
the top side comprises a channel; and
a bore extends from the top side to the bottom side receiving the fastener.
5. The height-adjustable base member of claim 4 , further comprising:
a channel nut retained in the channel, the channel nut comprising a threaded bore for threadably receiving the fastener.
6. The height-adjustable base member of claim 4 , further comprising:
a rail comprising a channel slidably receiving the channel clamping member, wherein in the first mode the rail is adjustable in one dimension with respect to the channel clamping member, and wherein in the second mode the rail is locked with respect to the channel clamping member.
7. The height-adjustable base member of claim 6 , wherein the rail comprises two rail flanges arranged at a distal end of the channel, wherein the two rail flanges complementarily engage the two flanges of the channel clamping member.
8. The height-adjustable base member of claim 1 , further comprising:
a traveling washer arranged between a head of the fastener and the lever.
9. The height-adjustable base member of claim 8 , wherein the arm comprises a stop configured to limit the range of motion of the traveling washer when traveling between the first mode and the second mode.
10. The height adjustable base member of claim 1 , further comprising:
an L-foot comprising a horizontally arranged component and a vertically arranged component, wherein the arm is adjustably coupled to the vertically arranged component.
11. The height-adjustable base member of claim 10 , wherein the arm and L-foot comprise textured mating surfaces.
