THE SHORT ANSWER
After detach-and-reset work, the monitoring map may no longer match the roof. Rebuild the device-to-position record before diagnosing individual panels.
Preserve both layouts
Save the pre-removal monitoring screenshot, removal inventory, roof plan and current digital layout. Do not drag panels into positions based only on visual symmetry; virtual devices need to match actual serials and field locations.
Audit component custody
Compare module, optimizer or microinverter identifiers recorded during removal with those reinstalled. Note replacements and missing labels. DOE maintenance guidance values complete equipment and corrective-work records. [1] The inventory should state uncertainty rather than silently filling gaps.
Verify roof positions safely
Use contractor photographs and qualified field documentation, not homeowner roof access. Confirm array planes, rows and orientation. If the physical design changed, check whether permit, engineering or utility records also need an update.
Separate mapping from faults
A device can produce while displayed in the wrong position; another can be correctly placed but offline. Resolve the map, communications and electrical condition as separate tasks. Do not order replacement hardware from a mislocated gray tile alone.
Close warranties and handoff
Save final serial map, service report and production baseline. If a component was damaged or replaced, retain the written warranty decision; federal guidance makes the specific warrantor and remedy important. [2] Give the homeowner owner-level access to the corrected layout.
