If you’ve already got solar panels or you’re thinking about going solar, adding a solar battery could be the next step to slashing your power bills and taking more control over your energy use. But how much can you actually save with a solar battery—and is it worth it?
Here’s a breakdown of what savings look like, how the numbers stack up in 2025, and why more Mackay households are adding batteries to their solar systems.
What Do Solar Batteries Actually Save You?
A solar battery stores the excess energy your solar panels produce, instead of sending it back to the grid for a low feed-in tariff. That stored energy can then be used when the sun’s not shining—like at night, during peak times, or in a blackout.
Here’s how it adds up:
- Avoid peak energy rates – Use stored solar power when electricity prices are highest
- Lower your power bill – Reduce how much energy you buy from the grid
- More self-consumption – Use more of your own power instead of exporting it for cents
- Back-up power during outages – Save the cost and stress of food spoilage, lost work, or downtime
With a well-sized solar battery system, some homeowners are saving $800–$2,000+ per year on electricity.
How Much Could You Save in Mackay?
Savings will depend on your energy usage, solar system size, and battery capacity. But here’s a rough example based on average households in Mackay:
| Scenario | Without Battery | With Solar Battery |
|---|---|---|
| Annual electricity bill | $2,400–$3,200 | $600–$1,400 |
| Average annual savings | – | $1,200–$1,800+ |
| Payback period (with finance) | – | 6–9 years |

What Makes a Solar Battery Worth It?
A solar battery adds value in more ways than just the dollar figure. In Mackay’s humid climate and with storm-related blackouts not uncommon, a battery gives you both savings and reliability.
- Use your solar energy at night
- Avoid rising electricity prices
- Keep your home powered during outages
- Reduce your reliance on energy retailers
- Increase the return on your solar system
And with new federal battery rebates launching soon, upfront costs could drop significantly—making solar storage even more cost-effective.
