Path-Q Solar
What should a buyer inspect before purchasing a home with existing solar panels?
Answer
A buyer should verify the system's condition, ownership, performance history, warranties, permits, roof condition, and any continuing payment or service obligations before closing. The inspection should cover both the equipment and the documents that transfer with the home.
Key points
- Obtain the contract, invoices, warranties, monitoring records, maintenance history, and utility interconnection information.
- Determine whether the system is owned, financed, leased, or subject to a power-purchase agreement.
- Have a qualified inspector or solar professional assess visible equipment, wiring, mounting, inverter status, and roof interfaces.
- Compare recent production with the system's documented expectations while accounting for weather and shading.
- Confirm that permits, approvals, and transferable warranties are available.
What it depends on
- System ownership and contract structure
- Age, design, condition, and monitoring data
- Roof condition and local permitting or utility records
Risks and trade-offs
- A low purchase price may conceal loan, lease, repair, or roof-removal obligations.
- Production records may be incomplete or not directly comparable to estimates.
- A system may have limited warranty coverage if ownership or transfer requirements were not followed.
Information you may need
