Question

How many solar cells could be solder in a series ,without effecting their efficiency considering shunt resista

Answer 1

For a series connection of PV cells, the resistance rises in direct proportion to the voltage while the current remains constant; the resistive voltage drop is directly proportional to the number of cells.  This means the efficiency remains constant regardless of how many cells are connected.
