In a photovoltaic array with multiple panels connected serially, which consequence results when a single panel experiences reverse bias?

💡 Explanation

Reverse bias protection is implemented with bypass diodes; without them, reverse voltage causes significant power dissipation due to the parasitic resistance, inducing reverse current flow and substantial heat because the panel acts like a load rather than a source therefore, potential hotspots and thermal runaway occur rather than uniform power distribution.
