As Australians look for ways to cut their energy bills and reduce their environmental footprint, solar batteries have become a hot topic. But the question on everyone’s mind is: how much does a solar battery cost, and is it really worth it?
In this article, we’ll break down the true cost of solar battery storage, how the Cheaper Home Battery Rebate affects pricing, and whether solar batteries are a smart investment for Sydney homes and businesses.
💰 How Much Does a Solar Battery Cost in Australia?
The cost of a solar battery system depends on several factors, including brand, capacity, installation, and whether it’s part of a solar panel + battery combo.
Here’s a general price breakdown in Australia (before rebates):
| Battery Capacity | Estimated Cost (Installed) |
|---|---|
| 5 kWh | $5,000 – $7,000 |
| 10 kWh | $8,000 – $12,000 |
| 13.5 kWh (e.g., Tesla Powerwall) | $13,000 – $16,000 |
| 20+ kWh Commercial-Grade | $18,000+ |
✅ Note: Larger batteries cost more but may offer better long-term savings, especially for high-consumption households or businesses.

🧠 Are Solar Batteries Worth It?
If your home or business:
- Uses most of its power in the evening
- Experiences frequent blackouts
