Path-Q Solar

What should a home buyer inspect before purchasing a house with solar panels?

Answer

Inspect the system's ownership and obligations, physical condition, roof interface, electrical work, performance history, warranties, permits, monitoring, and insurance implications. Treat the solar equipment and any battery or contract as part of the home's due diligence, not merely as an appliance.

Key points

  • Determine whether the system is owned, financed, leased, or governed by a service contract.
  • Check panels, mounting, wiring, inverter, battery, disconnects, and visible signs of water intrusion or damage.
  • Review permits, inspection records, warranties, maintenance history, and monitoring access.
  • Assess roof age and whether future roof work could require removal and reinstallation.

What it depends on

  • System ownership and contract terms
  • Equipment age, condition, and warranty coverage
  • Roof condition and electrical service
  • Local permit, inspection, insurance, and disclosure requirements

Risks and trade-offs

  • A low purchase price can conceal contract obligations or near-term replacement costs.
  • Poor installation or roof penetrations can create leak and safety risks.
  • Production estimates may not reflect actual output because of shading, equipment faults, or changing conditions.

Information you may need

  • Solar contracts, invoices, warranties, permits, and service records
  • Recent production and utility records
  • Roof inspection and electrical inspection
  • Insurance and lender requirements

Your next step

What to do next

Make the purchase contingent on review of the solar documents and obtain an independent roof and electrical inspection plus a performance review.
