1. A solar power system comprising:
a rail having an end, an interior top surface, an interior bottom surface, and an exterior top surface;
a solar module disposed atop the exterior top surface of the rail; and
an end clamp, at least a portion of the end clamp disposed inside the rail at the end of the rail, the end clamp comprising:
a fastener having a head end and a tail end;
a clamping plate disposed at least partially outside of the rail comprising a clamping plate wedge disposed inside the rail, wherein the clamping plate secures the solar module to the exterior top surface of the rail,
an inner wedge disposed inside the rail and coupled to the interior bottom surface,
a block disposed between and engaged with the clamping plate wedge and inner wedge, wherein
the tail end of the fastener is engaged with the inner wedge to apply a first force in a first horizontal direction on the inner wedge, wherein the head end of the fastener is engaged with the clamping plate to apply a second force in a second horizontal direction on the clamping plate, and wherein the inner wedge and clamping plate wedge impart a vertical force onto the block in a vertical direction to cause the block to engage with the interior top surface.
