Path-Q Solar

What should I do if one part of my solar array stops reporting data?

Answer

First determine whether only monitoring communication has failed or whether that section has stopped producing. Check the monitoring timestamp, inverter or optimizer status, related alerts, and recent power or internet interruptions; do not access the roof or electrical equipment unless qualified.

Key points

  • Compare the affected section with other sections under similar weather conditions.
  • Check whether the issue is limited to the monitoring platform, gateway, inverter, optimizer, or actual generation.
  • Document when the data stopped, the alerts shown, and any recent outages or work.
  • Use the installer, monitoring provider, or equipment warranty contact for diagnosis.

What it depends on

  • System architecture and monitoring granularity
  • Whether the missing section has a separate inverter, optimizer, or gateway
  • Recent internet, grid, weather, or maintenance events
  • Warranty and service arrangements

Risks and trade-offs

  • A communication fault can hide a production fault.
  • A localized electrical fault may present a safety risk even if the rest of the array operates.
  • Repeated resets can make diagnosis harder or affect warranty support.

Information you may need

  • Affected section and equipment identifier
  • Last successful report and current alert messages
  • Production comparison with other sections
  • Recent power, internet, weather, or construction events

Your next step

What to do next

Capture screenshots and timestamps, perform only documented owner-level checks, and open a service request with the installer or monitoring provider.
