Solar Panels Not Working in San Diego — What to Check First

Check these first (no tools needed)

• Look at your inverter — is it showing a green light?
• Red or flashing light = fault code, check the display
• Check your solar app/monitoring dashboard
• Look for any tripped breakers in your main panel
• Check if any tree growth is newly shading panels
• Power outage? Most inverters shut off automatically (safety)

Common issues and fixes

• Inverter fault/error: often clears with restart
• Grid outage: microinverters/hybrids auto-reconnect
• Dirty panels: cleaning can restore 5–25% output
• Single panel underperforming: likely a micro-inverter issue
• Monitoring offline: check Wi-Fi/router, not the panels

When to call a pro

• Inverter won't restart after 24 hours
• Multiple error codes / display is blank
• Physical damage visible on panels or wiring
• System is more than 5 years old with no maintenance
• Production is consistently 30%+ below estimate
