We designed and built these inverters that can work on the 0.5 volt output of an individual cell. I built discreet component prototypes and then designed the chips. With 0.5 volt currents and voltages are small so you need only thin cheap wires. Our MPPT nano-inverters than aggregate the 6V output of one cell with the 60 cells to any multiple of 6V and thereby lowering the current even more than standard panels with cells in a string. See my other descriptions of the nano-inverters in this HN discussion.
