Post-repair verification

Post-repair verification means checking, once a repair is done, that the fault is fixed and the affected circuit or tracker row works normally again. It is the last step in repairs for Bypass Diode Failure, Module Hotspot from Cell Damage, Cable Defect and Performance Loss from Tracker Twist. After replacing modules or diode assemblies for a failed bypass diode, check how the string behaves. After replacing a module for a cell-damage hotspot, retest the string current. After replacing or rerouting damaged DC cable, confirm that the insulation is intact. After a tracker twist repair, run a new survey of row angles. Compare normalized power with unaffected rows under stable irradiance, through both the morning and afternoon sweep windows. Repeat the check across several tracker positions, because a twisted row can look fine at one angle and fail at another. The sources give no figures for how effective this check is. They describe it only as a confirmation step that follows the corrective work itself.

<!-- review notes

• sentence 6: support check: partial - The passages say a twisted row can look acceptable at one position and fail at another and mention several fixed positions, but the explicit post-repair repeat across several positions is not stated; they only cover diagnostics and morning/afternoon sweeps.
• sentence 7: support check: partial - No effectiveness figures appear and the check is described as a post-repair step, but the passages do not themselves state that no figures exist; this is an absence claim. -->
