Path-Q Solar

What documents should I keep after a solar installation is finished?

Answer

Keep the signed contract, final design and equipment list, invoices and payment records, permits and inspection records, warranties, commissioning results, monitoring access, manuals, roof information, and maintenance or repair history. These records support operation, warranty claims, insurance, future roof work, and property transfer.

Key points

  • Record panel, inverter, battery, optimizer, and monitoring serial numbers.
  • Keep the final as-built layout, electrical diagrams, shutdown instructions, and contact details for responsible providers.
  • Save production estimates and commissioning data so later performance can be compared with the original design.
  • Store digital copies in a durable, accessible location and update the file after every service visit.

What it depends on

  • System equipment and configuration
  • Contract, warranty, financing, and ownership arrangements
  • Local permitting and inspection process
  • Insurance and future roof or property plans

Risks and trade-offs

  • Missing documents can delay troubleshooting, claims, roof work, or a property sale.
  • Monitoring credentials and system information should be stored securely.

Information you may need

  • Final system design and equipment serial numbers
  • Permit, inspection, and commissioning records
  • Warranty, contract, financing, and insurance documents
  • Shutdown, maintenance, and provider-contact instructions
