1. Why should I install solar panels for my home in Victoria?
Solar panels help reduce your electricity bills, protect you from rising energy prices, and lower your carbon footprint. With Victorian rebates and incentives, installation becomes even more affordable.
2. Does Greentastic install both solar panels and solar battery systems?

3. What rebates are available for solar panels and batteries in Victoria?
Victorian homeowners may be eligible for:
- Solar Victoria Solar Panel Rebate
- Solar Battery Rebate
- Small-scale Technology Certificates (STCs)
These rebates can significantly reduce the upfront installation cost.
4. How do I know if I am eligible for solar rebates?
Eligibility depends on factors such as:
- You own the property (owner-occupied or rental)
- Your household income falls within the required threshold
- Your home does not have an existing solar system (for panel rebate)
Greentastic helps customers check eligibility and guides them through the full application process.
5. How much does a solar panel system cost in Melbourne?
The cost depends on system size, brand, roof type, and whether you add a battery. After rebates, most homeowners find the installation far more affordable. Greentastic provides accurate, customised quotes based on your home’s needs.
6. What size solar system do I need?
We recommend a system after assessing your:
- Daily electricity usage
- Roof space
- Budget
- Long-term energy goals
Most Melbourne homes benefit from a 6.6kW–10kW solar system.
7. Do solar batteries really help reduce electricity bills?
Yes. A battery stores excess solar energy for use at night or during peak times. This reduces grid dependency and further lowers your bills. Batteries also provide backup power during outages.

We offer a range of trusted, high-performance brands including:
- Alpha ESS
- GoodWe
- Growatt
- Neovolt
