QR Codes at Solar Farms: Panel Identification, Inverter Logs, and O&M Workflows

1. Panel and String Identification

Each panel or string combiner carries a QR linking to its exact location on the farm map, model and serial, current string ID, and performance data from the monitoring system.

2. Fault Logging

O&M technicians scan the panel or inverter QR to open a fault log form pre-filled with the asset ID. They describe the fault, upload a photo, and submit. The CMMS creates a work order automatically.

3. Inverter Logs

A QR on each inverter cabinet links to the inverter's historical performance log, current status, and alarm history. No need to log in to a central system when standing in the field.

4. Drone Inspection Reports

After a thermal drone survey, the inspection report links each identified hotspot to the panel's QR record. Technicians scan on-site to confirm the correct panel and log the corrective action.
