Keep the sunshine you have banked

A solar and battery system is a long-term asset. Aura Illumination provides expert maintenance services that protect your investment, preserve generation performance and ensure your system remains safe and compliant for years to come.

Solar panels and battery storage systems are built to last, but they are not maintenance-free. Like any electrical infrastructure exposed to the elements and operating continuously, they degrade, develop faults and accumulate issues that reduce performance over time. Dust, soiling, micro-cracks in cells, degraded DC isolators, loose DC string connections and ageing inverter components all quietly chip away at your system output. At Aura Illumination, our solar maintenance service restores what time and weather take away.

Comprehensive solar system inspections

Our solar inspections go well beyond a visual walk-around. We carry calibrated DC clamp meters, insulation resistance testers, IV curve tracers and thermal imaging cameras. A full inspection includes string-by-string current and voltage testing to identify underperforming strings, DC insulation resistance testing to detect degraded wiring before it becomes a fire risk, visual inspection of panel condition and mounting systems, and a complete review of inverter data logs against modelled generation expectations.

The inspection report we produce is actionable. Every finding is documented with photographic evidence, its likely cause, its impact on generation and a prioritised recommendation. You leave with a clear picture of your system health, not a vague summary.

Battery storage maintenance and safety testing

Battery storage systems introduce additional complexity. Cell balancing, battery management system firmware, thermal management and DC protection all require periodic attention. We service battery installations from all major commercial platforms, checking BMS data logs for cell voltage imbalance, capacity fade trends and fault histories that may not be visible from the monitoring dashboard. DC isolators and overcurrent protection within battery circuits are also inspected and tested.

What our solar and battery maintenance covers

  • IV curve tracing and string-by-string performance testing
  • Thermal imaging of panels, junction boxes and inverter components
  • DC insulation resistance testing and earth fault detection
  • Inverter servicing, firmware updates and data log analysis
  • Battery BMS review, capacity testing and protection device inspection

Thermal imaging is one of the highest-value tools in solar maintenance. Hot spots caused by cell defects, bypass diode failures or soiling are invisible to the eye but stand out clearly in an infrared image. We carry out thermal scans during peak generation periods to capture panels under real operating conditions, producing images that your panel manufacturer can act on if warranty claims are warranted.

Compliance, AS/NZS 5033 and safety

Solar photovoltaic systems in Australia are governed by AS/NZS 5033 and, for grid-connected systems, the requirements of AS/NZS 4777. Systems that have degraded DC isolators, compromised insulation or unapproved modifications may no longer meet these standards and can represent both safety risks and insurance liabilities. Our maintenance inspections are carried out against these standards, and we issue a compliance report for every system we service.

Ongoing monitoring and scheduled maintenance plans

The most cost-effective approach to solar and battery maintenance is a scheduled programme rather than reactive call-outs after a fault is noticed on the monitoring portal. We offer annual and biannual maintenance plans that give commercial and industrial operators predictable costs, priority scheduling and a documented maintenance history that adds value when refinancing or selling the property.

Good to know

How often should a commercial solar system be inspected? +

For most commercial systems, we recommend a full electrical inspection and performance test every twelve months. Systems in dusty environments, coastal locations or those with a history of inverter alarms may benefit from more frequent visits. An annual inspection is also good practice for maintaining insurance coverage and manufacturer warranties.

Our monitoring shows generation has dropped — can you diagnose why? +

Yes. A drop in generation output is usually caused by panel soiling, string faults, inverter issues or shading changes. We carry out a systematic diagnostic including IV curve tracing and thermal imaging to pinpoint the cause and provide a remediation plan. In many cases, the cause is straightforward and quickly resolved.

Can you service solar systems installed by other contractors? +

Absolutely. We service solar and battery installations regardless of who installed them. We ask for any available system documentation before the first visit so we can review the original design, but if documentation is unavailable, our inspection process captures what we need from the installed system.
