Path-Q Solar

How can a buyer determine whether an existing solar system has been modified without approval?

Answer

Compare the installed system with permit, utility, design, and equipment records, and have a qualified professional inspect for changes that are not documented.

Key points

  • Compare panel, inverter, battery, racking, wiring, disconnect, and monitoring details with approved plans and original invoices.
  • Look for added or removed equipment, altered wiring, extra circuits, relocated components, and mismatched serial numbers.
  • Request final inspection, permission-to-operate, utility, monitoring, and maintenance records.

What it depends on

  • Available permit and utility records
  • The original system design and equipment list
  • The quality and scope of the inspection

Risks and trade-offs

  • Undocumented modifications may create safety, warranty, insurance, financing, or resale problems.
  • A visual inspection may not identify concealed wiring or software changes.
  • Correcting past work may require redesign, inspection, or replacement.

Information you may need

  • Approved plans and permit records
  • Utility interconnection and operating records
  • Original and current equipment lists
  • Independent inspection findings
