Snap-lock photovoltaic module mounting system
A photovoltaic (PV) module clamp may be configured to interface with a torque tube and a PV module rail fixedly coupled to a PV module. The PV module clamp may include a seating portion made of two or more lateral walls and a base surface. A clamp body of the PV module clamp may be coupled to the seating portion. The clamp body may include a shape corresponding to a cross-sectional shape of the torque tube. The PV module clamp may include a fastening feature for interlocking the PV module clamp with the PV module rail responsive to the PV module rail being seated in the seating portion of the PV module clamp.
1. A mounting system for photovoltaic (PV) modules comprising:
a module rail configured to be secured to a PV module, the module rail having a first lateral wall, a second lateral wall, and a base portion that connects at least portions of bottom edges of the first and second lateral walls;
a first wire form module clamp having a first end, a second end, and a curve forming a first fastening loop between the first and second ends, wherein the first and second ends are secured to the first and second lateral walls of the module rail;
a second wire form module clamp having a first end, a second end, and a curve forming a second fastening loop between the first and second ends, wherein the first and second ends are secured to the first and second lateral walls of the module rail; and
a fastener that couples the first fastening loop to the second fastening loop, such that in a coupled configuration, the first and second wire form module clamps are configured to secure the module rail to a torque tube;
wherein:
to secure the first wire form module clamp to the module rail, the first and second ends of the first wire form module clamp are inserted through holes defined by the first and second lateral walls, respectively; and
to secure the second wire form module clamp to the module rail, the first and second ends of the second wire form module clamp are inserted through holes defined by the first and second lateral walls, respectively.
2. The mounting system of claim 1 , wherein the first and second wire form module clamps are pivotally secured to the module rail such that a distance between the first and second fastening loops may be selectively adjusted.
3. The mounting system of claim 1 , wherein hook shapes are formed in the first and second ends of the first and second wire form module clamps to maintain the first and second wire form module clamps within the holes defined by the first and second lateral walls.
4. The mounting system of claim 1 , wherein the first and second wire form module clamps each comprise a single length of wire having a circular cross-sectional shape.
5. The mounting system of claim 1 , wherein the first and second wire form module clamps are shaped to interface with an outer surface of the torque tube.
6. The mounting system of claim 5 , wherein the first and second wire form module clamps include bends that are consistent with a polygonal shaped torque tube.
7. The mounting system of claim 1 , wherein the fastener can be selectively tightened to decrease a distance between the first and second fastening loops and increase a locking force between the first and second wire form module clamps and the torque tube.
8. The mounting system of claim 7 , wherein the fastener includes a bolt.
