Who Is Residential Solar Perth For?
Our residential service is for Perth homeowners who want a properly designed system rather than a standard package based only on panel count. We help with first-time installations, new homes, older system upgrades and properties preparing for batteries, backup power or EV charging.
Installing solar for the first time
Match solar production to your current Synergy usage, available roof space and the times your household normally consumes electricity.
Learn how solar works →Building a new Perth home
Coordinate solar design early so conduits, switchboard allowances, inverter locations and future battery infrastructure can be planned before construction finishes.
Explore new-build solar →Upgrading an existing system
Assess your existing panels, inverter, metering, electrical infrastructure and roof layout before adding capacity, replacing equipment or integrating a battery.
Review solar upgrade options →How We Design Residential Solar Perth Systems
Solar system size should not be selected from a price list alone. Australis Solar reviews the property, electrical infrastructure and household usage before recommending panel, inverter, battery or backup capacity.
Residential Solar Perth Options
We recommend equipment and system architecture after reviewing your usage and property. The right design may be solar-only, battery-ready or a complete solar, storage and backup system.
Custom rooftop solar systems
Panel layout and inverter capacity designed around usable roof area, shading, energy consumption and the amount of solar power your home can use directly.
Compare solar panel options →Store excess solar for later
Battery capacity matched to evening consumption, solar surplus, tariff strategy, backup duration and expected future loads rather than a generic package size.
Explore solar batteries →Support selected or whole-home loads
Backup design considers inverter output, battery state of charge, circuit priorities and the difference between energy capacity and available backup power.
View backup installations →Prepare your home for an EV
Coordinate solar generation, battery operation, switchboard capacity and charger selection so your home is ready for practical daytime or overnight charging.
Explore EV chargers →Our Residential Solar Perth Process
Australis Solar manages design, approvals, installation and handover through one local team. Site visits are arranged when required for accepted or technically complex projects.
Review your goals
We discuss your bill, household usage, budget, property, battery interest, backup priorities and future EV plans.
Model the property
We review roof imagery, orientation, shading, nearby structures, available panel space and likely system production.
Prepare your proposal
You receive recommended equipment, system sizing, estimated production and clearly explained options where appropriate.
Approve and install
Our team manages required applications, installation planning, electrical work, commissioning and system handover.
New and changed inverter systems generally require a Western Power embedded generation connection application. Eligibility for Synergy export credits depends on the customer, tariff and system configuration. Read the official Western Power connection guidance and Synergy DEBS information.

Residential Solar Perth FAQs
Practical answers about system sizing, batteries, roof design, approvals and residential installation.
What size solar system does a Perth home need?
The appropriate size depends on annual consumption, daytime usage, available roof area, shading, inverter limits and future loads. A household planning an EV, electric hot water or a battery may benefit from considering those loads during the original design rather than sizing only for current use.
How do you calculate the recommended system size?
Australis Solar reviews your Synergy bill, available interval data, roof layout, solar access, electrical supply and future energy goals. We then model likely solar production and compare it with how and when the home consumes electricity.
Can residential solar be installed now and a battery added later?
Often, yes. However, future battery compatibility depends on inverter selection, system architecture, switchboard capacity, battery location and current network requirements. Planning for storage during the initial design can reduce avoidable equipment changes later.
Will solar panels power my house during a blackout?
A standard grid-connected solar system normally shuts down during an outage for network safety. Blackout support requires compatible equipment and a properly designed backup arrangement. Available power and duration depend on inverter output, battery capacity, state of charge and the circuits connected to backup.
Does roof orientation matter for residential solar?
Yes, but north-facing panels are not the only useful option. East-facing panels may produce earlier in the day, while west-facing panels may better support afternoon consumption. The final layout should account for shading, roof space and when your household uses electricity.
Do I need Western Power and Synergy approval?
New or changed inverter systems generally require an embedded generation connection application. Synergy eligibility and export arrangements depend on your tariff, customer category and system configuration. Australis Solar manages applicable applications as part of an accepted installation.
Can you upgrade an older residential solar system?
Yes, subject to inspection and compatibility. We can assess the existing inverter, panels, mounting, cabling, metering, switchboard and roof space before recommending replacement, expansion or battery integration. Visit our solar upgrades page for more information.
Which areas does Australis Solar service?
Australis Solar installs and supports residential solar systems throughout the Perth metropolitan area. Project availability can depend on location, access, system complexity and the work required.
