Path-Q Solar

What credentials should a home buyer check before hiring an independent provider to review monitoring data and assess an inherited solar system's performance?

Answer

Check that the provider has relevant solar design, electrical, diagnostic, and safety competence, carries appropriate insurance, and is authorized to perform the proposed work. Verify credentials with the applicable licensing authority and ask for references involving inherited or unfamiliar systems.

Key points

  • Confirm the business identity, applicable electrical or solar licenses, and any required contractor registration.
  • Ask about experience with the system's inverter, monitoring platform, battery, and mounting type.
  • Require evidence of general liability and workers' compensation coverage where applicable.
  • Obtain a written scope distinguishing data review, physical inspection, testing, repair recommendations, and any work requiring permits.

What it depends on

  • The system's equipment and location
  • The scope of review requested
  • Applicable licensing, safety, and permit requirements
  • Whether the provider will access energized equipment or the roof

Risks and trade-offs

  • A data analyst may not be qualified to perform electrical or roof inspections.
  • A provider who also sells replacement equipment may have a conflict when recommending upgrades.
  • Credentials alone do not establish competence with obsolete or unusual equipment.

Information you may need

  • Equipment inventory and monitoring access
  • Provider license and registration details
  • Insurance certificates and relevant references
  • Written inspection methodology and deliverables
