AI Customer ServiceHow does the resistance theoretically behave for most commercially available photovoltaic modules, when an external DC voltage is applied to them, with and without illumination? It's common to wire solar panels of the same voltage in parallel, in order to provide greater current or greater resilience to partial shade.
The characteristic resistance of a solar cell is the cell's output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point.
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.
Presumably, it can be inferred from this that solar panels consistently have considerable resistance (relative to their rated voltage) when not illuminated— otherwise, having different light intensities on the parallel modules would cause significant current and waste heat to go through the panels at a lower voltage. Is this correct?
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.
For example, commercial silicon solar cells are very high current and low voltage devices. A 156 mm (6 inch) square solar cell has a current of 9 or 10 amps and a maximum power point voltage of 0.6 volts giving a characteristic resistance, R CH, of 0.067 Ω. A 72 cell module from the same cells has R CH = 4 to 5 ohm.
