Path-Q Solar

How can I document solar underproduction before making a warranty claim?

Answer

Build a dated record linking the system's expected performance to measured production, availability, weather, and any faults. Preserve original monitoring exports, utility data, invoices, service records, photos, and communications, and follow the warranty's required notice and testing procedure.

Key points

  • Record daily or monthly production from the monitoring system and compare it with the contract or warranty measurement basis.
  • Save inverter status, alerts, downtime, maintenance, and reset history rather than relying only on screenshots.
  • Use utility-meter data where relevant, but distinguish solar production from on-site consumption and exported energy.
  • Note unusual shading, snow, soiling, construction, outages, and weather conditions.

What it depends on

  • The warranty's definition of output and measurement period
  • Availability and accuracy of monitoring data
  • Contract production assumptions and exclusions
  • Utility-meter records and system commissioning date
  • Required claim notice and inspection procedure

Risks and trade-offs

  • Monitoring estimates may not be sufficient if the warranty requires tested or meter-based evidence.
  • Incomplete records can delay a claim or make responsibility difficult to establish.
  • Resetting equipment or cleaning panels without recording the condition can remove useful evidence.

Information you may need

  • Warranty and contract claim instructions
  • Monitoring exports and inverter logs
  • Utility bills or interval data
  • Weather, outage, maintenance, and site-change records

Your next step

What to do next

Create a chronological evidence file and ask the installer or manufacturer what measurement method and inspection records it requires before opening the claim.
