How does the resistance of a photovoltaic module behave?
How 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.
Do solar panels have resistance if not illuminated?
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?
