With electricity prices continuing to rise and feed-in tariffs dropping, more Australians are asking: “Is solar battery storage still worth the investment in 2025?”
The short answer? Yes—but only if you do it right.
In this article, we’ll break it down in simple terms—how solar battery storage works, what it costs, how much you can save, and why it’s more valuable than ever with smart systems like Redx AI leading the way.
What Is Solar Battery Storage and How Does It Work?
During the day, solar panels typically produce more electricity than your house requires. That excess energy is sent to the grid for a tiny credit (called a feed-in tariff) in the absence of a battery. A solar battery stores that excess energy so you can use it later—especially at night when electricity rates are higher. This helps you:
- Use more of your own solar power
- Reduce how much you buy from the grid
- Protect yourself from blackouts
- Save money on electricity bills
Is It Worth It? What to Consider in 2025
1. Rising Electricity Prices
In 2025, grid electricity is more expensive than ever—especially during peak hours. A solar battery helps you avoid those expensive rates by using your own stored power when prices surge.
2. Lower Feed-in Tariffs
The amount you get for selling power back to the grid has dropped a lot. It now makes more sense to store your energy and use it later than to export it.
3. More Government Incentives
Some states are still offering battery rebates or VPP programs, making it more affordable to invest in storage than just a few years ago.
4. Backup Power for Peace of Mind
Extreme weather and grid failures are becoming more common. With battery storage, your lights stay on when others go out.
How Much Does a Solar Battery Save You?
The savings depend on:
✅ Your daily electricity usage
✅ Your solar panel size
✅ Battery size
✅ Whether you have smart automation (more on that soon)
For many households, a battery can cut electricity bills by 40–60%. But if you add energy trading capabilities, you can do even better.
Example – Standard vs Smart Battery System
Let’s say two families have the same solar + battery setup:
| Feature | Family A (Basic Battery) | Family B (Battery + Redx AI) |
|---|---|---|
| Stores solar power | ✅ Yes | ✅ Yes |
| Avoids peak prices | ✅ Yes | ✅ Yes |
| Smart energy trading | ❌ No | ✅ Yes |
| Access to wholesale market | ❌ No | ✅ Yes |
| Earns bill credit | ❌ Rarely | ✅ Often |
| Total 5-month result | $415 bill | $954 credit |
