A method for stringing photovoltaic (PV) cells together and a system for the combined tabbing and stringing of photovoltaic (PV) cells for assembly into solar cell arrays. Multiple ribbons are first soldered simultaneously (or nearly so) to the front and back surfaces of individual PV cells (tabbing). After tabbing, PV cells are then loaded into a stringer subsystem which solders the front side ribbons of a first PV cell to the back side ribbons of the neighboring PV cell to form strings of PV cells wired in series. The tabber stringer system then loads completed strings into a frame containing a solar cell array being manufactured. The dual-ribbon method of PV cell interconnection reduces the electrical resistance between the cells in a string, thereby raising the solar cell array output power.
