Solar Upgrade Perth: Panels, Batteries, Inverters & Backup
Australis Solar provides solar upgrade services for Perth homes and businesses with older, undersized or changing energy systems. We assess your Synergy bill, roof, existing panels and inverter, switchboard, backup needs and future battery or EV goals before recommending whether to expand, replace or reconfigure your system.

Is a Solar Upgrade Right for Your Property?
A solar upgrade can suit homeowners and businesses whose electricity use, technology or future plans have moved beyond the system originally installed.
Your system is older or undersized
Smaller systems may no longer produce enough energy for current household loads, air conditioning or increased daytime use.
Your electricity use has increased
Working from home, a growing family, pool equipment or replacing gas appliances can materially change your energy profile.
You want to add battery storage
Your existing inverter, switchboard, meter and available battery location must be checked before a suitable retrofit is selected.
You need blackout protection
Backup requires compatible equipment, appropriate battery capacity and a clear decision about which circuits need support.
You are preparing for an EV
Additional solar, energy monitoring, battery storage and controlled EV charging can be planned together rather than added separately.
Your inverter is failing or unsupported
An inverter replacement can also be an opportunity to improve monitoring, battery compatibility and available solar capacity.
What We Assess Before Recommending a Solar Upgrade
Adding more panels is not automatically the best answer. Australis Solar checks the existing system, property limitations and future energy requirements before designing an upgrade pathway.
- Synergy bill and usage Annual consumption, seasonal changes, tariffs, exports and when electricity is used.
- Existing solar equipment Panel quantity, capacity, condition, inverter model, warranty, monitoring and previous faults.
- Roof and shading Available roof space, orientation, pitch, access, obstructions and nearby shading.
- Inverter compatibility Input limits, available trackers, string design, oversizing, communication and battery compatibility.
- Switchboard and supply Available space, protection devices, metering, earthing and whether the property has single-phase or three-phase supply.
- Network requirements Existing connection approval, proposed inverter capacity, export limits and any Western Power application requirements.
- Battery and backup needs Suitable battery position, usable capacity, inverter output, essential circuits and expected outage loads.
- Future energy goals EV charging, electric hot water, induction cooking, additional air conditioning and planned property changes.
How Our Solar Upgrade Process Works
We gather the right information first, compare practical options and coordinate the electrical and network requirements before installation.
-
1
Send your system details
Provide a recent Synergy bill, property address and photos of your inverter, switchboard, meter and existing panels where available.
-
2
Desktop assessment
We review your usage, roof layout, current equipment, supply, proposed loads and likely compatibility.
-
3
Compare upgrade options
Suitable options are modelled with clear equipment, production, battery, backup and pricing assumptions.
-
4
Approvals and planning
Australis Solar coordinates the required Western Power, Synergy, metering and installation planning steps.
-
5
Install and commission
Our in-house team completes the electrical work, testing, commissioning, monitoring setup and customer handover.
WA Approvals, Export Limits and Solar Upgrade Incentives
A compliant upgrade must account for the electricity network, current product requirements, accreditation rules and the eligibility conditions applying to any available incentives.
Western Power connection approval
An Embedded Generation Connection application is generally required when installing a new inverter, changing or relocating an existing inverter, or adding another generation source such as a battery.
Review Western Power guidanceInverter and export limits
The approved inverter capacity and permitted export level can affect system design. Solar production first supplies loads at the property, with eligible excess energy exported subject to the approved limit.
Learn how export limits workSolar PV STC eligibility
Eligible new panel capacity may qualify for Small-scale Technology Certificates when the upgraded system, equipment, installation and total capacity meet current requirements. Existing capacity that has already received STCs cannot be claimed again.
Check Clean Energy Regulator guidanceAccredited design and installation
Eligibility for the Small-scale Renewable Energy Scheme requires appropriately accredited designers and installers, together with approved products and compliant electrical work.

Solar Upgrade FAQs
Answers depend on the existing equipment and property, but these are the main considerations for Perth customers.
Can I add more panels to my existing solar system?
Sometimes. The existing inverter must have suitable input capacity, available trackers and a compliant string arrangement. Australis Solar also checks roof space, panel compatibility and Western Power approval before recommending additional panels.
Do I need a new inverter for a solar upgrade?
Not always. A suitable existing inverter may support additional panels. A replacement may be recommended where the inverter is undersized, ageing, unsupported, incompatible with a battery or unable to meet the proposed design requirements.
Is it better to expand or replace an older solar system?
This depends on the condition, age, remaining warranty and compatibility of the existing equipment. A full replacement can be more practical when the old system restricts roof space, monitoring, battery integration or the size of the proposed upgrade.
Can a battery be added to existing solar?
Many systems can be retrofitted with battery storage using a compatible hybrid or AC-coupled solution. The assessment must also consider the switchboard, meter, battery position, network approval, usable capacity and whether blackout backup is required.
Will a solar upgrade affect my feed-in arrangement?
It may. Changes to the inverter, generation capacity, meter or connection approval can affect the applicable export and buyback arrangements. Australis Solar reviews the proposed configuration, but customers should also confirm current account arrangements with Synergy.
Will upgraded solar work during a blackout?
A standard grid-connected solar system normally shuts down during a grid outage. Backup operation requires compatible equipment and a design that accounts for battery capacity, inverter output and the circuits or loads that need continued power.
Are STCs available for a solar upgrade?
Eligible new solar capacity may qualify when the equipment and complete installation meet current requirements. Existing panels or capacity that have already received STCs cannot be claimed again. Battery incentives have separate eligibility rules.
How long does a solar upgrade take?
Timing depends on design complexity, equipment availability, access, switchboard work and the required network or metering approvals. Installation duration is confirmed once the final scope has been assessed.
