Keep a single handover pack
Match serial numbers and installed models with the final quotation and invoices. Retain layout drawings, test reports, commissioning evidence and application references. Obtain monitoring access controlled by you, and understand what the display measures before treating a missing reading as equipment failure.
Agree a safe maintenance plan
Ask the installer for cleaning and inspection guidance suited to the roof, equipment and access. Do not climb an unsafe roof or open live electrical equipment. Escalate damaged cables, loose fittings or unusual smells to a qualified service provider. Keep a record of faults, actions and receipts.
Know the warranty route
A performance warranty is not a promise of a fixed monthly electricity bill. Product and workmanship claims may have different contacts, exclusions and costs. Get the process in writing, using the warranty questions as a start, including whether labour, transport and reinstallation are covered, and who handles disputes if the original salesperson leaves.

Can I clean panels whenever I want?
Follow the installer/manufacturer's safe procedure and access guidance. Roof height and electrical risks may require a trained service provider.
