As the distance between adjacent bus bars is shorter in 5BB modules, the current path is shorter leading to higher output. Additional busbars creates lower resistance between cells. Ohms Law tells us that as resistance (ohms, R, or) go down, the current (amps) goes up. And when current goes up for the same voltage, power (which is volts times amps) goes up.
I = Current (amp), V = Voltage (volts), R = Resistance, P = Power (watts). The result of the additional busbars is that the solar panels are about 2% more efficient. This means that they can output 2% more power in the same size solar panel. As their manufacturing process gets more and more efficient, they can increase the wattage of their standard 36 cell solar panels.
