System Maintenance

Solar PV systems are like any electrical equipment that need to be regularly maintained for safe and efficient use. Regular maintenance should be carried out in accordance with the maintenance schedule and manufacturer’s instructions. 

​

Never attempt electrical repairs yourself

Maintenance must be conducted by a qualified person who is aware of the electrical risks with solar panels. Contact Coastwide Solar or your electrician for full maintenance, or to repair any damage to the solar panels such as loose fittings or exposed cables.

Cleaning solar panels

In many instances solar panels are self-cleaning from the occassional rain shower. Quite simply if the panels look clean then then they do not require cleaning. If the panels are visably dirty or there is a build up of debris which require removal then only a suitable qualified person should perform the work:

• use water, not cleaning products

• do not use scourers or other abrasive cleaners

• avoid using high pressure water cleaners

• not rest buckets or lean on the panels.

Things to check

• Check all panels for, discolouration or other obvious defects.

• Ensure the panels and supporting frames are firmly secured and free from debris.

• Make sure that the fittings and cables at the panels and the inverter remain securely attached.

• Review the inverter display panel for any recorded faults (refer to the manufacturer’s instructions for advice).

• Check that emergency procedures for shut down and isolation are clearly displayed.

• Make sure that the cooling vents of the inverter are clear of debris.

• Ensure access to the isolator switches is not impeded.

Additional tips

• Look out for overhead powerlines near the solar installation.

• Take care when working on ladders or at heights.

• Cut back trees and remove structures that cause shading of the panels (shading can reduce the efficiency and safety of the panels).
