Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
Resistance is the opposition that a substance offers to the flow of electric current. There are various solar panel output parameters that can be measured and obtained during flash test, helping to judge on the performance quality of a solar panel.
The series resistance will effect on I-V Curve of solar module. As the maximum power Pmax is the product of maximum voltage and current, the Pmax will also change with change in I-V Curve. Condition 1: At series resistance Rs = 0/cm2 the cell generates maximum power and it is the product of Vmax and Imax.
SHUNT RESISTANCE (Rsh) = Low shunt resistance causes power losses in solar cells by providing an alternate current path for the light-generated current. Such a diversion reduces the amount of current flowing through the solar cell junction and reduces the voltage from the solar cell.
Two solar panels will have an open circuit voltage and effective internal series resistance of 24 volts plus 24 ohms. This means that the short circuit current is 24 volts / 24 ohms = 1 amp. My queation is for theoritical understanding and not a practical one. What make me confuse is the contradiction in ohms law.
