Why Many Aussie Homes Are Choosing Battery Storage
With rising electricity prices and increasingly unpredictable energy supply, many homeowners are looking for ways to gain energy independence, and battery storage is fast becoming a go-to solution. Installing a home battery system doesn’t just store excess solar power; it unlocks flexibility, cost savings, and resilience for your household.
1. Save More by Using Your Solar Power Not Exporting It
If you have or plan to install solar panels, chances are you’ll often generate more electricity during the day than you immediately need. Without a battery, this surplus energy is either exported to the grid, often at low feed-in tariffs, or wasted. A home battery lets you store that excess energy and use it later, when demand (and electricity prices) is higher in the evening, morning, or on cloudy days.
- Increase your self-consumption rate and reduce reliance on grid electricity.
- Turn your rooftop solar into 24-hour home power, not just daytime savings.
- Offset peak evening electricity prices by using your stored solar energy.
2. Gain Energy Independence & Stability
A battery provides you with a buffer, especially useful if electricity rates rise or the grid becomes unreliable. With battery storage, your home has access to backup energy during outages or peak demand times.
- Keep essential appliances running during blackouts (lights, refrigeration, communications).
- Avoid unpredictable price hikes from electricity providers.
- Enjoy greater control over when and how you consume power.
3. Future-Proof Your Home for EVs, Heat Pumps & More
As Aussie households increasingly adopt electric vehicles (EVs), heat-pump hot water, reverse-cycle air conditioning, and other electric appliances having a battery become more valuable. A home battery ensures your solar energy supports not just lighting or small appliances, but the full range of your future energy needs.
- Power EV charging overnight using stored solar electricity.
- Support high-demand appliances like heat-pump hot water or ducted air-conditioning.
- Scale energy use sustainably without disproportionately rising bills.
4. Maximise Rebates & Government Incentives
Many states, including Victoria, offer rebates, subsidies, or incentives for battery and solar installations. By pairing solar with storage, you often make yourself eligible for better rebates and enjoy stronger long-term returns.
Plus, a battery helps you make the most of solar incentives by increasing your overall savings and reducing payback time.
- Lower upfront cost through rebate discounts.
- Better return on investment when the package includes solar + battery + efficient home upgrades.
- Greater long-term financial benefits, including reduced energy bills and higher self-reliance.
5. Boost Your Home Value & Appeal
Homes equipped with solar + battery systems are increasingly sought after. They deliver ongoing cost savings, sustainability credentials, and energy reliability, all attractive to future buyers or renters.
- Add resale value by offering lower ongoing energy costs and energy independence.
- Appeal to eco-conscious buyers who prioritize sustainability and a lower carbon footprint.
- Make your property stand out as a modern, energy-efficient home.
Is a Battery System Right for You? Here Are Some Quick Checks
Before deciding, it’s smart to review these factors to make sure a battery will deliver for your household:
- Do you generate more solar electricity during the day than you use?
- Do you use a lot of power during evenings for heating, cooling, EV charging, and appliances?
- Do you want backup power during grid outages or blackouts?
- Are you planning to electrify more of your home, e.g., replace gas heating with electric heat pumps?
- Do you qualify for rebates or incentives in your region (e.g., through state/federal programs)?
If you answered “yes” to any of the above, a battery system could be a smart, cost-effective upgrade that pays off over time.

Frequently Asked Questions
No, you don’t need solar panels to install a home battery. Although a battery works best when paired with solar, it can be installed on its own. In that case, the battery will charge from the grid during low-tariff hours and discharge when electricity prices are higher. For maximum savings and energy independence, a solar + battery combination is ideal.
Most modern home batteries have a lifespan of around 10–15 years, depending on usage patterns and battery chemistry. Many retain about 80–90% of their original capacity even after the warranty period. Proper installation, correct system sizing and avoiding frequent deep discharges also help extend battery life.
The ideal battery size depends on several factors:
- Evening and overnight energy usage
- Size of your solar system
- Number of large appliances (HVAC, heat pump, EV charger, etc.)
- Whether you want full-home or partial backup
As a general guide, many homes use batteries in the 10–30 kWh range, while larger homes or those with EVs and higher loads may need 20–50 kWh.
A home battery can significantly reduce your electricity bill but may not eliminate it entirely unless both your solar and storage system are large enough to cover all your usage patterns year-round. Most homeowners typically see 40–80% reductions in their bills, depending on system size, tariff structure and lifestyle.
Yes, a home battery can power your home during a blackout, but only if it supports backup mode and is installed with the correct backup hardware (such as a backup gateway or essential load circuit). Some batteries offer whole-home backup, while others support only selected essential circuits. Your installer can configure the system based on your backup priorities.
Yes, many households in Victoria and across Australia may be eligible for rebates or incentives that reduce the upfront cost of a home battery. The exact rebates depend on your state, local programs and system type. As part of EcoGreen Homes’ free assessment, a rebate eligibility check is included to help you understand what support you can access.
Most home battery installations take around 3–6 hours, depending on the complexity of the site, backup configuration and any switchboard upgrades required. In many cases, same-day installation and commissioning are possible, so your system can be up and running quickly.
