What happened

In May 2023, a fire tore through the roof of the departure terminal at Rarotonga International Airport. Cook Islands News reported that reports had found electrical arcing from the solar panel connectors to be the cause. Repairs to the roof followed. Injuries, the exact date, and any effect on airport operations were not reported in the available text.

Contributing factors

Reports cited electrical arcing at the solar panel connectors. No further detail on how the connectors failed is available from the published text.

Lessons learned

Roof-mounted solar connectors should be inspected regularly for damage, looseness and overheating.
Thermal imaging or arc-fault detection should be considered where it can find connection faults early.
Arrays on occupied buildings should be arranged so a faulty circuit can be isolated and firefighters can reach the roof.

More lessons on maintenance, inspection and ageing assets, detection and monitoring, fire suppression and firefighting, from every incident on the register.
