Path-Q Solar

What documents should a buyer request before purchasing a home with an existing solar system?

Answer

Request documents that establish who owns the system, what obligations transfer, how it has performed, what remains under warranty, and whether it was properly approved and interconnected. Do not assume that panels belong to the seller or transfer automatically with the property.

Key points

  • Ask for the purchase agreement, lease, loan, power-purchase agreement, or other financing and ownership records.
  • Request warranties for panels, inverters, mounting, workmanship, and any battery or monitoring equipment.
  • Obtain installation plans, permits, inspection or approval records, interconnection records, and system specifications.
  • Review production and maintenance records, monitoring access, repair history, and unresolved faults.
  • Confirm whether there are liens, transfer fees, consent requirements, insurance conditions, or service obligations.

What it depends on

  • Whether the system is owned, financed, leased, or covered by an energy-service agreement
  • The age, equipment type, and maintenance history of the system
  • Whether documents and warranties are transferable
  • The property contract and applicable local approval or utility requirements

Risks and trade-offs

  • Assuming ownership can leave the buyer responsible for payments or transfer conditions.
  • Missing permits or interconnection records can complicate insurance, resale, or service.
  • A warranty may exclude labor, roof work, removal, or transfer to a new owner.
  • Production records may not be comparable without accounting for weather, shading, outages, and system changes.

Information you may need

  • All contracts, account statements, payoff or transfer terms, and lien information
  • Equipment list, commissioning date, warranties, manuals, and monitoring credentials
  • Permits, inspection records, interconnection approval, and utility account details
  • Several years of production and electricity-use records, if available
  • Any repair, error, insurance, roof, or legal correspondence

Your next step

What to do next

Make the purchase contingent on document review and have the conveyancer, lender, or other appropriate adviser confirm that the solar obligations and approvals can transfer to you.
