A photovoltaic module mounting assembly including a photovoltaic module lever lock and base portion for attaching photovoltaic modules to a roof surface. The base portion includes one or more parallel channels that provide access to one or more corresponding recesses formed in a top surface of the base portion. The lever lock includes a lobe at one end, a torque lever at the other and supports a photovoltaic module connector. The lobe is dimensioned to fit into the channel at a first orientation, and upon rotation of approximately 90 degrees, to fit into the recess at a second orientation. The module connector may support two or more photovoltaic modules.
