Thinking about adding a solar battery to your home? Here’s what Blue Mountains homeowners need to know about current battery rebates, solar storage savings and how to prepare your home for battery installation.
If you’ve been considering adding a solar battery to your existing solar system, 2026 is a good time to review your options. With government battery support now available, many homeowners are looking at how battery storage can help reduce electricity bills, increase solar self-consumption and provide greater energy independence.
At Avery Solar & Electrical, we help homeowners across the Blue Mountains, Penrith, Nepean and Hawkesbury regions understand their solar and battery options. Whether you already have rooftop solar or are planning a new solar and battery installation, the right advice can make a big difference to your long-term savings.

What Is the Cheaper Home Batteries Program?
The Australian Government’s Cheaper Home Batteries Program provides an upfront discount on eligible small-scale battery systems connected to new or existing rooftop solar.
The program is designed to make battery storage more affordable for households, businesses and community organisations. Instead of homeowners applying directly for a separate rebate, the discount is usually applied through the accredited installer or battery retailer as an upfront reduction on the cost of the battery system.
For Blue Mountains homeowners, this means a solar battery may now be more accessible than it was in previous years, especially for homes that already have solar panels and use a lot of power in the evening.
Who Can Benefit from the Battery Discount?
The battery discount may be available for eligible residential and non-residential premises, including homes, businesses and community organisations. Eligible battery systems must meet program requirements, including battery capacity, product approval and installer accreditation.
In general, the program supports eligible small-scale batteries connected to solar PV systems. This can include batteries installed with a new solar system or batteries added to an existing solar panel system.
For the most accurate and current eligibility details, homeowners should check the official Australian Government guidance or speak with an accredited solar and battery installer before making a decision.
Why Solar Batteries Are Becoming More Popular
Solar panels generate most of their power during the day. A battery allows you to store unused solar energy and use it later, such as in the evening, overnight or during peak electricity periods.
This can be especially useful for households that:
- Use most of their electricity after sunset.
- Want to reduce reliance on the grid.
- Want to make better use of their solar power.
- Are concerned about rising electricity costs.
- Want backup power options during outages, where suitable.
- Are planning for future electric vehicle charging.
For many Blue Mountains homes, a battery can help improve the value of an existing solar system by increasing self-consumption. Instead of exporting excess solar power to the grid for a low feed-in tariff, homeowners can store more of their own energy for later use.
What Happened to the NSW Battery Rebate?
NSW previously offered a battery installation discount through state-based energy saving programs. However, this has changed since the introduction of the Australian Government’s Cheaper Home Batteries Program.
The NSW Government has advised that its battery installation discount has been suspended because the federal battery program provides a larger battery discount from 1 July 2025. This means homeowners should now look first at the Australian Government battery discount when considering a new solar battery installation.
However, NSW battery support has not disappeared completely. Eligible battery owners may still be able to access a NSW Government incentive by connecting their battery to a Virtual Power Plant.
What Is the NSW Virtual Power Plant Incentive?
A Virtual Power Plant, or VPP, allows eligible batteries to share stored energy with the grid when needed. In return, homeowners may receive an upfront incentive and may also receive ongoing payments depending on their VPP provider and agreement.
For some households, joining a VPP may help improve the financial return from a battery. However, every provider has different terms, conditions and payment structures, so it is important to compare offers carefully before signing up.
A VPP is not right for every homeowner. If you want more control over your stored energy or backup power settings, you should ask questions about how the battery will be managed before joining a program.
Can You Combine Federal and NSW Battery Support?
In many cases, homeowners can use the Australian Government battery discount for the battery installation and then explore the NSW VPP incentive if they choose to connect their eligible battery to a Virtual Power Plant.
The important point is that the old NSW battery installation discount and the Australian Government battery discount are not the same thing. Homeowners should avoid assuming that every rebate or incentive can be combined. Always check the current rules before committing to a quote.
Is a Solar Battery Worth It for Blue Mountains Homes?
A solar battery can be a smart upgrade, but it depends on your energy usage, electricity plan, solar system size and household routine.
A battery may be a good fit if your home:
- Already has solar panels and exports a lot of unused solar energy.
- Uses most of its power in the evening.
- Has high electricity bills despite having solar.
- Wants greater energy independence.
- Would benefit from backup power options.
- Is planning future upgrades such as EV charging or electric hot water.
For homes with low evening usage or limited solar export, a battery may not deliver the same return. That is why a proper assessment is important before choosing a battery size or brand.
Why Battery Size Matters
Bigger is not always better when it comes to solar batteries. The best battery size is usually the one that matches your solar generation, evening electricity use and future energy goals.
If a battery is too small, it may not store enough energy to support your household when you need it most. If it is too large, you may pay for storage capacity you do not regularly use.
Avery Solar & Electrical can review your electricity bills, solar system performance and household usage pattern to recommend a battery size that makes practical sense.

Adding a Battery to an Existing Solar System
If you already have solar panels, you may be able to add a battery to your existing system. The best approach depends on the type of inverter you have, the age of your solar system, available switchboard capacity and whether your system was designed with battery storage in mind.
Before adding a battery, it is worth checking:
- Your current solar system size.
- Your inverter type and compatibility.
- Your switchboard condition.
- Your average daily solar export.
- Your evening and overnight electricity usage.
- Whether backup circuits are required.
Some older systems may need upgrades before battery storage can be installed safely and effectively. Our team can assess your current setup and explain the best pathway.
Installing Solar and Battery Storage Together
If you are planning a new solar installation, it may be worth considering battery storage at the same time. Even if you do not install a battery immediately, a battery-ready solar design can make future upgrades easier.
For new systems, Avery Solar & Electrical can help design a solution that considers:
- Your current household energy usage.
- Future energy needs.
- Battery compatibility.
- EV charging plans.
- Backup power requirements.
- Roof space and solar panel layout.
This helps ensure your solar panel system is designed for long-term performance, not just today’s energy bill.
Why Local Installation Experience Matters
Blue Mountains homes can present different installation conditions from standard suburban properties. Roof pitch, shade, bushland settings, older switchboards and access requirements can all affect system design.
Working with a local solar and battery installer means your system can be designed around your property, not a generic package. Avery Solar & Electrical understands the local region and provides practical recommendations based on real site conditions.

How to Prepare for a Solar Battery Quote
Before requesting a battery quote, it helps to gather a few details. This allows your installer to recommend a system that suits your home and avoids unnecessary oversizing.
Useful information includes:
- A recent electricity bill.
- Details of your current solar system, if installed.
- Your inverter brand and model, if known.
- Typical daytime and evening energy usage.
- Whether you want backup power.
- Any future plans for EV charging or electric appliances.
With this information, Avery Solar & Electrical can provide clearer advice on battery size, expected benefits and installation requirements.
