In various representative aspects, a clamp assembly that secures a solar panel module to a rail support structure that utilizes a generally c-shaped clamp in combination with a t-bolt and a binding bolt such that the t-bolt and binding bolt fit through a pair of apertures in the c-shaped clamp. This enables the foot of the t-bolt to be inserted into a guide on the top of the rail support structure so that the clamp can subsequently secure the solar panel module to the rail support structure by rotating the binding bolt, which in turn locks the t-bolt within the guide and the top of the clamp is then tightened with continuous rotation of the binding bolt, which also enables raised portions on the foot of the t-bolt and top of the clamp to create an electrical bonding path between the solar panel module and the rail support structure.
