Clear advice

Solar monitoring, warranties and aftercare

Handover should leave the owner able to see whether the system is working and who to contact when it is not. Product paperwork matters, but so do monitoring access, fault records and a practical route back to the installer.

Arrange a site assessment

Monitoring belongs with the property

The owner should control the monitoring account and receive the login details at handover. Normal production varies with season and weather, so the useful baseline is the design forecast and the system’s own history rather than a single good day.

Alerts need to reach someone who can act. That is particularly important for a holiday home where a communications failure, tripped circuit or battery warning may otherwise sit unnoticed.

A warranty is not the same as a repair plan

Panel, inverter and battery warranties cover different faults for different periods. The handover pack should identify model and serial numbers, commissioning records, electrical certificates and the route for making a claim.

Island support should be discussed before purchase. Access, replacement stock and travel to a remote property can affect how quickly a fault is inspected even when the manufacturer accepts the claim.

Questions owners ask

Before the survey.

Who should own the solar monitoring account?+

The property owner should have permanent access. An installer may also retain service access, but it should not replace the owner’s login.

What documents should I receive after installation?+

Keep the final design, equipment schedule, serial numbers, commissioning record, electrical certificates, registration evidence, warranties and monitoring details.

Do solar panels need regular servicing?+

They have few moving parts, but production data, electrical protection, mounting condition and visible damage should still be checked. Cleaning depends on dirt, access and manufacturer guidance.
