Installation Process
1. Consultation & Site Assessment
We start with a detailed consultation to understand your energy goals. Our experts will then conduct a thorough on-site audit at your property to assess your roof, check your existing electrical setup, and complete a full safety and compliance review.
2. System Design & Quote
Based on the assessment, we design a custom solar system perfectly sized for your needs. You’ll receive a transparent, itemized quote that breaks down the system capacity (kW), battery storage (kWh), recommended brands, and a clear project timeline.
3. Approvals & Scheduling
We handle all the paperwork for you. Our team manages the grid connection applications and any necessary permits. Once everything is approved, we’ll contact you to confirm your installation booking.
4. Installation & Integration
Our certified technicians will carry out the complete installation. This includes professionally mounting the panels, wiring the system, and integrating the solar inverter, protection devices, and any batteries (like the Tesla Powerwall shown).
5. Testing & Commissioning
This is the exciting part. We thoroughly test the entire system to ensure it’s running at peak performance. We’ll commission the hardware, activate any backup circuits you’ve selected, and set up the monitoring app on your phone so you can track your energy production.
Best Battery Storage In Australia
CEC-Approved Batteries & Government Rebates
When it comes to battery storage, quality and compliance should always be the first priorities. In Australia, CEC (Clean Energy Council) approval is the gold standard, ensuring your battery is safe, reliable, and built for long-term performance. Choosing a CEC-approved battery means it’s been tested against strict industry standards, giving you peace of mind that your system is both efficient and dependable.
The added bonus is that CEC-approved products make you eligible for government rebates and incentives, which can significantly reduce the upfront cost of installation. While states like South Australia and Victoria have well-known rebate programs, households in NSW can also access incentives that make the switch to solar batteries more affordable.
Working with accredited installers is just as important. Not only does it guarantee the system is installed correctly, but it also protects your investment with proper warranties. Going for cheaper, non-approved options might seem tempting at first, but it often means missing out on rebates and putting performance—or even safety—at risk.
At Austar Solar, we make the whole process easy for you. From supplying and installing CEC-approved batteries designed for Australian conditions to taking care of all the rebate paperwork in NSW, we handle everything—so you can enjoy reliable, clean energy without the hassle.

The process typically includes:
- Site inspection and energy assessment

A qualified installer ensures compliance with NSW regulations and safety standards.
