Abstract: Embodiments create groupings of singulated strips of mixed (chamfered; rectangular) footprint/outline/perimeter types. The groupings exhibit a consistent ratio of chamfered strips to rectangular strips. These groupings can then be freely incorporated into solar modules in order to offer a pleasingly uniform appearance.

Abstract: Embodiments relate to a solar module comprising a plurality of photovoltaic (PV) elements (strips) arranged in series in an overlapping shingled configuration to provide a string. Conducting wires exhibiting low series resistance are disposed along the direction of serial connection of the strips. The wires overlap and are in contact with conducting fingers exhibiting higher series resistance, that extend in other than the direction of serial connection. The fingers receive current from underlying areas of the shingled strip. The current is collected by the wire and transmitted along the line of serial electrical communication. Because the photovoltaic (PV) current is carried primarily by the wires (rather than the fingers), series resistance can be reduced and Fill Factor (FF) may be improved. This in turn leads to lower Cell-To-Module (CTM) loss and higher module power.
