Solar Battery Perth: Home Battery Storage & Installation

A home battery gives you more control over the solar energy your property produces.

Instead of exporting all of your excess solar during the day, a battery can store part of that energy for use later, including in the evening when your panels are no longer generating.

For Perth households that already have solar, or are planning a new solar and battery system, storage can help increase solar self-consumption and reduce the amount of electricity purchased from the grid.

SolarAide provides solar battery installation across Perth from our Bayswater WA branch. We design battery systems around your existing solar setup, household electricity use, evening demand and future energy plans rather than simply recommending the largest battery available.

Why Are Perth Homeowners Adding Solar Batteries?

Solar panels do most of their generating during daylight hours. The problem is that household electricity demand does not always happen at the same time.

A Perth home may produce surplus solar in the middle of the day but use much more electricity later in the afternoon and evening.

A home battery helps bridge that gap.

With the right system, you can store some of the excess electricity generated by your solar panels and use it later instead of immediately sending it back to the grid.

For many households, a battery can help with:

• Increasing the amount of rooftop solar used at home
• Reducing evening grid electricity consumption
• Storing excess daytime solar generation
• Preparing for higher future electricity demand
• Supporting selected backup loads where the system is designed for it
• Participating in an eligible Virtual Power Plant
• Getting more value from an existing solar system

The right outcome depends on how much solar you generate and when your household actually uses electricity.

Solar Battery Incentives for Perth Homes

Battery incentives are another reason Perth homeowners are taking a fresh look at storage.

Eligible Synergy customers can currently receive up to $1,300 through the WA Residential Battery Scheme, calculated on usable battery capacity up to 10kWh. Eligible Horizon Power customers in other parts of WA may receive different support.

The WA scheme can also operate alongside support available through the Australian Government’s Cheaper Home Batteries Program.

Eligibility conditions apply, and incentive values can change over time.

For the full details, including eligibility, VPP requirements and current support, see our WA Battery Rebate guide.

Can I Add a Battery to My Existing Solar System?

In many cases, yes.

You do not necessarily need to replace your current solar panels just because you want to add battery storage.

The first step is checking how your existing system has been configured.

We look at factors such as:

• Your existing solar array
• Current inverter
• Inverter and battery compatibility
• Switchboard configuration
• Available installation space
• Solar exports
• Daytime and evening electricity use
• Desired battery capacity
• Backup requirements

Some existing solar systems can accommodate battery storage relatively easily.

Others may require an inverter change, additional equipment or a different battery configuration.

The WA Government also confirms that batteries can be installed with existing solar systems, although some properties may require additional technology or system reconfiguration.

That is why we assess the current setup before recommending equipment.

How Does a Solar Battery Work?

During the day, your solar panels generate electricity.

Your home uses that electricity first.

When the solar system produces more electricity than the property needs, that surplus can either be exported to the grid or used to charge your battery.

Later, when solar generation falls, the stored electricity can be discharged to help power the home.

A typical daily cycle may look something like this:

Morning: Solar generation begins increasing.

Middle of the day: Solar powers the home and excess generation charges the battery.

Afternoon and evening: Solar production falls while household electricity use often increases.

Evening: Stored battery energy can be used before drawing additional electricity from the grid.

The exact behaviour depends on the battery, inverter, electricity tariff, solar production and system settings.

What Size Solar Battery Does a Perth Home Need?

There is no single battery size that suits every household.

A 10kWh battery may suit one property and be completely wrong for the house next door.

We normally start by looking at:

Your evening electricity consumption

If most of your electricity is used after sunset, battery storage may have more opportunity to reduce grid imports.

Your excess solar generation

A battery needs something to charge it.

If your existing solar system exports significant electricity during the day, there may be useful surplus generation available for storage.

Your existing solar system size

A larger battery does not automatically deliver more value if the solar system cannot regularly charge it.

Future electricity use

Your electricity consumption could increase if you plan to add an electric vehicle, electric hot water, electric cooking or other large loads.

Backup requirements

A household that wants selected essential circuits available during an outage may require a different configuration from someone primarily focused on solar self-consumption.

The WA state rebate is calculated on usable battery capacity up to 10kWh, but this does not mean 10kWh is automatically the correct system size for every Perth home.

We size the battery around the property first and consider available incentives second.

Do Perth Battery Systems Need to Join a VPP?

If you want to receive support through the WA Residential Battery Scheme, Virtual Power Plant participation is part of the eligibility requirements.

A VPP links participating home batteries so that stored electricity can be coordinated to support the electricity network during certain periods.

Eligible Synergy customers must participate in a qualifying VPP arrangement, while Horizon Power customers have corresponding requirements.

Depending on the VPP product, households may also receive financial benefits when stored electricity is used to support the grid.

The conditions vary between VPP products, so it is worth understanding the agreement before choosing your battery solely around a rebate.

Can a Solar Battery Keep My Home Running During a Blackout?

Potentially, but a battery does not automatically mean the entire home will stay powered during an outage.

Backup capability depends on the:

• Battery
• Inverter
• Electrical configuration
• Backup hardware
• Circuits selected for backup
• Available battery charge

Some households choose to back up only essential loads, such as refrigeration, lighting, internet equipment and selected power outlets.

Other properties may require broader backup capability.

If blackout protection matters to you, mention it during the initial battery assessment so the system can be designed appropriately.

Solar Battery Installation for New Solar Systems

If you are installing solar and battery storage together, both systems can be designed as one energy solution from the beginning.

This allows us to consider:

• Solar panel capacity
• Battery capacity
• Hybrid inverter options
• Roof space
• Household consumption
• Daytime generation
• Evening demand
• Future electricity requirements
• Monitoring
• Backup requirements

Planning the system together can reduce the likelihood of choosing solar equipment today that makes adding battery storage unnecessarily complicated later.

For homeowners starting from scratch, see our solar panels Perth service.

Battery Storage for Existing Perth Solar Systems

Already generating solar?

A battery retrofit can allow you to store more of the electricity your panels are already producing.

We assess your existing system and determine whether the current inverter can work with the proposed battery or whether another configuration would make more sense.

The aim is not to replace equipment unnecessarily.

It is to build a battery system that works properly with what is already installed.

Our Solar Battery Installation Process

1. Home Energy Assessment

We review your electricity consumption, existing solar system, inverter, solar exports and what you want the battery to achieve.

2. Battery System Design

We recommend battery capacity and system architecture based on your actual electricity profile rather than choosing capacity solely because it qualifies for an incentive.

3. Compatibility and Eligibility Check

For existing solar systems, we check equipment compatibility.

Where applicable, current WA and federal battery incentive requirements are also reviewed before the installation proceeds.

4. Installation and Commissioning

The battery system is installed, configured and commissioned for your property.

Where supported by the selected system, monitoring is also configured so you can see how the battery charges and discharges.

5. System Handover

We explain the system operation, monitoring and relevant settings so you know what the battery is doing after installation day.

The goal is fairly simple: install the battery that suits the property rather than the battery that makes the biggest number on a quote.

Solar Battery Perth FAQs

How much is the WA battery rebate in Perth?

Eligible Synergy customers can currently receive up to $1,300 through the WA Residential Battery Scheme. The maximum state rebate is based on up to 10kWh of usable battery capacity. Eligibility conditions apply.

For detailed and regularly updated information, see our WA Battery Rebate guide.

Can I combine the WA battery rebate with the federal battery program?

The WA Government states that its Residential Battery Scheme complements the federal Cheaper Home Batteries Program, allowing eligible installations to benefit from both programs subject to their respective requirements.

Do I need solar panels to install a home battery?

A home battery can technically be configured in different ways, but batteries are commonly paired with rooftop solar so surplus daytime generation can be stored for later use.

If you do not currently have solar, SolarAide can assess a combined solar and battery system.

Can SolarAide add a battery to my existing solar system?

In many cases, yes.

We first check your existing panels, inverter and electrical configuration to determine the most suitable retrofit approach.

What size battery should I install?

The right size depends on your household electricity use, solar generation, evening demand and future requirements.

Battery size should not be selected solely according to the maximum rebate available.

Do I need to join a VPP?

VPP participation is required if you are claiming the WA Residential Battery Scheme rebate.

Can a battery power my home during a blackout?

Some systems can provide backup electricity, but the level of backup depends on the battery, inverter and electrical design.

If backup power is a priority, it should be included in the system design from the beginning.

How long does a battery installation take?

Installation time varies depending on the property, existing solar equipment, switchboard, battery location and system configuration.

SolarAide will confirm the expected installation requirements after assessing the property.
