System health

Find out why your solar is underperforming

A change in output does not always mean the panels have failed. Seasonal sunlight, new shading, inverter errors and monitoring interruptions can all change what you see.

Share your system details, electricity bills, monitoring records and any error messages. We use those alongside a site inspection to investigate the likely cause and explain what work, if any, is appropriate.

Do not access rooftop panels or open electrical equipment yourself. If there is visible damage or a safety concern, keep clear and contact a licensed electrician.

Equipment

Inverter assessment and replacement

An older or faulty inverter may need attention, but replacement should follow an assessment. We consider the fault, panel configuration, electrical condition and manufacturer warranty information before recommending a compatible option.

If you are also considering a battery, we discuss that at the same time so an inverter decision takes your future plans into account. Compatibility must still be checked for the specific equipment.

Changing needs

Assess whether an expansion makes sense

New appliances, electric hot water or different household routines can change your electricity demand. More panels may help, but existing inverter capacity, roof space, shading and network limits all matter.

We assess an expansion against alternatives such as an inverter upgrade or a replacement system. Your written quote explains the proposed work and the equipment that will be retained or replaced.

Adding storage

Older systems inspected for battery compatibility

Our accredited experts inspect older solar systems to confirm battery compatibility, rather than assume every existing system is ready for storage.

  • Inverter: model, condition and compatible battery arrangements.
  • Existing solar: panel configuration and equipment condition.
  • Switchboard: space, protection and any electrical upgrades required.
  • Battery location: suitable space, access and required clearances.

Every battery installation we complete includes full-home blackout protection. We explain the proposed backup configuration and the battery's operating limits before installation.

Ongoing care

Clear findings and practical next steps

After assessing your system, we explain the findings and any recommended work. Maintenance needs vary with the equipment, age and site conditions; we do not assume every system needs the same service.

Keep the original installation paperwork and manufacturer warranty documents where possible. They help identify the equipment and assess the available options. Any warranty eligibility depends on the manufacturer's terms and the circumstances of the fault.

FAQs

Common questions

Why is my solar system producing less power?

Weather, seasonal sunlight, shading, soiling, equipment faults and monitoring issues can all affect reported output. We compare the symptoms with the system's age, equipment and available data before recommending work.

Can you check whether my older solar system supports a battery?

Yes. Our accredited experts inspect older systems to confirm battery compatibility. We assess the inverter, panels, switchboard and proposed battery arrangement, then explain any additional equipment or upgrades needed.

Can I add more panels to my existing system?

Possibly. Roof space, inverter capacity, panel compatibility, electrical condition and network approval all need checking. Adding panels is not automatically the best option; we compare an expansion with other appropriate upgrades.

Does a faulty inverter always need replacing?

No. An error may relate to the supply, communication or another part of the system. We investigate first. If replacement is appropriate, we explain compatible options and any manufacturer warranty considerations.

How often should my solar system be inspected?

Follow the manufacturer's maintenance guidance and arrange an assessment if performance changes, an error appears or equipment is damaged. The appropriate inspection schedule depends on the equipment, age and site conditions.

What should I do if the equipment looks damaged or unsafe?

Keep clear of damaged equipment and wiring. Do not climb onto the roof or attempt electrical repairs. Contact a licensed electrician for advice, and call emergency services if there is immediate danger.
