Close monitoring

Close monitoring means tracking affected modules or strings over time instead of replacing them right away. For cell cracks, cracked modules are watched to see whether the damage progresses. Replace a cracked module only when severe inactive cell area or a hotspot risk has been confirmed. Until then, keep monitoring it. For cell interconnection failure, replace modules once the failure is electrically active. Before that point, reduce the mechanical or thermal stresses that drive it to get worse. After repairing a bypass diode failure, check how the string behaves to confirm the fix worked. Performance monitoring is a general measure that can lower the economic impact of many different failures. Finding faults early lets the owner repair them quickly and keep the system efficient. It may also prevent major damage such as fire or electric shock. Large plants with string-level monitoring can raise alarms on strings that produce too little. Small systems without monitoring are a limit: faults there often go unnoticed for weeks or months.

<!-- review notes

• sentence 1: support check: partial - The passage says to monitor cracked modules for progression, but the general definition of 'close monitoring' as tracking over time instead of immediate replacement is not stated.
• sentence 2: support check: partial - The passage says to replace modules with confirmed severe inactive-area or hotspot risk and to monitor cracked modules for progression, but 'only when' and 'until then keep monitoring' are stronger than stated. -->
