Which outcome occurs when a photovoltaic circuit's bypass diode fails short?

💡 Explanation

When a bypass diode fails short, the affected cells in the string become reverse biased during operation, because the entire string current flows through those cells, leading to significant power dissipation as heat. Therefore localized panel overheating results, rather than array loss, increased voltage, or grid synchronization issues which have different root causes.
