Keep Your Solar System Performing at Its Best with Excel Power
A well-maintained solar system helps reduce your electricity bills and keeps your home or business running efficiently. But when things go wrong—whether it’s a faulty inverter, underperforming solar panels, or a battery not holding charge—acting fast can make all the difference.
At Excel Power, we offer professional solar repair and maintenance services across Toowoomba and the Darling Downs, helping you get the most out of your solar setup year after year.
General Solar System Maintenance
Regular servicing keeps your solar system working safely, efficiently, and for the long haul. Our tailored solar maintenance plans include:
- Inspection of electrical components for wear, corrosion, or loose connections
- Cleaning and alignment of solar panels to maximise sunlight capture
- Battery and inverter performance testing
- System monitoring checks to ensure accurate data tracking
With local knowledge of Toowoomba’s climate—from dry summers to heavy storms—our team provides maintenance services built for Queensland conditions.
A dirty or neglected system can lose up to 20% efficiency—our maintenance services help you avoid that.
Inverter Repairs & Replacement
Your solar inverter is the heart of your system. If it’s showing error codes, not producing power, or physically damaged, your entire solar setup could be underperforming.
At Excel Power, we service all types of inverters:
- String inverters
- Hybrid inverters
- Off-grid and battery-compatible inverters
Common issues we fix:
- Error messages or no output
- Inverter not communicating with monitoring apps
- Overheating or unexpected shutdowns
Our team uses quality replacement parts and fast diagnostics to get your system back online—fast.
Damaged or Degrading Solar Panels
From cracked panels to dirty glass, even small issues can reduce your system’s efficiency. Dust, bird droppings, or shading problems can reduce performance by up to 20%.
At Excel Power, we offer:
- Safe, professional solar panel cleaning
- Replacement of damaged or cracked panels
- Visual and technical inspections to identify efficiency losses and shading problems
Tip: Toowoomba’s mix of dry conditions and storm debris means solar panel cleaning should be part of your regular maintenance routine.
Solar Battery Repairs & Upgrades
Your solar battery is essential for storing energy and providing power at night or during outages. If it’s not charging properly or failing to deliver stored power, we’ll help you restore or upgrade it.
Our services include:
- Diagnosis and repair of battery performance issues
- Upgrades to modern, high-efficiency battery storage systems
- Integration with hybrid or off-grid setups
Common battery issues we fix:
- Reduced capacity or fast discharge
- Faulty communication with inverters
- No backup during blackouts
We work with leading battery brands like Enphase, PowerPlus and Tesla to deliver reliable storage for your home or business.
Upgrading Outdated Solar Systems
If your solar system is more than 8–10 years old, you may not be getting the performance or savings you should. Technology has improved—and Excel Power can help you make the switch.
Reasons to upgrade your solar system:
- Replace ageing inverters with high-efficiency, hybrid-ready models
- Add or expand battery storage for more energy control
- Upgrade to smart monitoring systems to track usage in real time
- Ensure compatibility with EV chargers, energy management, or off-grid setups
Our team will assess your existing system and recommend upgrade options that maximise your return and fit your goals.
