Which risk increases significantly in a solar panel array due to shading when bypass diodes fail?

💡 Explanation

Reverse bias on shaded cells forces current through failing diodes; hotspot formation via increased reverse current creates a thermal runaway feedback, because ineffective *current bypassing* cannot shunt current, therefore cell breakdown increases rather than inverter failure under proper conditions.
