An attachment point apparatus and system for photovoltaic arrays is disclosed as well as an installed photovoltaic array using attachment apparatus. One embodiment provides a rail for receiving a PV module, including a rail member located substantially beneath at least a portion of a second photovoltaic module and having a first end located near a gap between a first and second photovoltaic modules. An embodiment also provides a second photovoltaic module which is substantially coplanar with and located between a first and third photovoltaic modules and wherein said rail member is connected to the first, second, and third photovoltaic modules and attached to a support structure by a first and second attachment brackets. A further embodiment provides a lever clip, said lever clip comprising a head portion connecting a photovoltaic module to a rail, a lever portion extending away from a head portion, and a retaining portion near an end of a lever portion wherein the lever portion acts as a lever to rotate the head portion during installation such that the head portion secures the photovoltaic module to a frame.
