Path-Q Solar

What should I do if one part of my solar array suddenly stops producing?

Answer

First check the monitoring system for a device alarm or communication outage and compare the affected section with the rest of the array. Do not open electrical equipment or climb onto the roof; document the time, alarms, weather, and production change, then contact the installer, equipment provider, or qualified electrician.

Key points

  • A fault may involve a panel, optimizer, microinverter, string inverter, wiring connection, breaker, shading event, or monitoring system.
  • Sudden loss of one section is more concerning than a gradual weather-related reduction.
  • Only qualified personnel should diagnose energized rooftop and electrical equipment.

What it depends on

  • System architecture
  • Monitoring detail and alarm codes
  • Weather, shading, and recent work
  • Warranty and service responsibility

Risks and trade-offs

  • Resetting equipment without understanding the fault can erase diagnostic information or create a hazard.
  • A hot, damaged, or burning component requires urgent professional attention and emergency response if there is fire risk.
  • Waiting can increase lost production or allow a wiring fault to worsen.

Information you may need

  • Affected array section and monitoring screenshots
  • Alarm codes and time the issue began
  • Recent weather, maintenance, or construction
  • System ownership, warranty, and service contact

Your next step

What to do next

Record the monitoring evidence and contact the responsible provider for a diagnostic visit; escalate immediately if there is smoke, burning odor, visible damage, or arcing.
