A system includes a plurality of photovoltaic modules installed on and arranged in an array on a roof deck. Each of the photovoltaic modules includes first and second ends, and a baseplate located at the first end. The baseplate of one of the photovoltaic modules is substantially aligned with the baseplate of an adjacent another one of the photovoltaic modules. The baseplate is configured to receive at least one electrical component. The substantially aligned baseplates include a longitudinal axis. The system includes at least one wire cover removably attached to at least one of the baseplates. The at least one wire cover is moveable in at least a first direction transverse relative to the longitudinal axis.
