Path-Q Solar

What should I ask about a solar system's maintenance history before buying the home?

Answer

Ask for records showing what was inspected, repaired, replaced, or monitored; whether faults or safety issues remain; and whether warranties and service rights transfer. Compare the records with current system performance and have the system professionally inspected if documentation is incomplete.

Key points

  • Request invoices, service reports, monitoring history, fault logs, inspection reports, and permit records.
  • Ask about inverter, optimizer, battery, roof, wiring, racking, animal, storm, and water-intrusion repairs.
  • Confirm whether panels, inverters, batteries, workmanship, and roof penetrations remain under warranty.
  • Check for unresolved alerts, inactive monitoring, damaged modules, corrosion, shading changes, or inaccessible equipment.
  • Obtain a written estimate for deferred maintenance and likely near-term replacements.

What it depends on

  • System age, design, and equipment types
  • Completeness and reliability of seller and installer records
  • Current production compared with a reasonable weather-adjusted baseline
  • Roof condition and access to equipment

Risks and trade-offs

  • A system can appear operational while having degraded output or latent roof and wiring problems.
  • An inspection may identify costs that affect the offer but cannot guarantee future performance.
  • Missing records can complicate warranty claims, monitoring access, and future resale.
  • Repairs may require coordinating solar work with roof or electrical work.

Information you may need

  • The equipment list and commissioning date
  • Maintenance, repair, warranty, permit, and inspection records
  • Recent monitoring and utility-production data
  • Any financing, lease, service, or transferable warranty documents

What to do next

Make access to records and a solar inspection a documented due-diligence condition, then obtain repair estimates for identified issues.
