Perth solar panel design and installation
Solar Panels Perth
Australis Solar supplies and installs solar panels for Perth homes and businesses. Since 2008, our WA-owned team has designed systems around each property’s Synergy bill, roof space, shading, energy use, switchboard and future battery or EV plans. Accredited in-house installers and licensed electricians complete the work.
Send a recent Synergy bill and your property address for a roof-specific recommendation. Final products and system capacity are confirmed after assessment.
Designed for the property
How we design solar panels for Perth properties
The right system is not determined by panel wattage alone. Australis Solar reviews the property, electricity usage and electrical infrastructure before recommending the array layout, inverter capacity and future battery pathway.
Synergy bill
Annual consumption, tariff information, seasonal changes and available import or export data.
Usage profile
Daytime, evening and overnight loads, including air conditioning, electric hot water and pool equipment.
Roof layout
Available area, orientation, pitch, roof material, storeys, obstructions and safe installation access.
Shading
Chimneys, trees, neighbouring buildings and roof features that may affect panel placement or string design.
Inverter design
Inverter capacity, panel strings, monitoring requirements and compatibility with the intended array.
Switchboard and supply
Single-phase or three-phase supply, protection, available space, cabling routes and possible upgrade work.
Battery pathway
Future storage capacity, inverter architecture, battery location, solar surplus and possible backup requirements.
Future electrical loads
EV charging, additional air conditioning, electric hot water, induction cooking or broader home electrification.

Compare solar panel options
Australis Solar commonly designs systems with AIKO and Trina Solar panels. The preferred option depends on roof space, required system capacity, appearance, inverter compatibility, budget and the complete system design.
AIKO solar panels
A high-efficiency panel pathway suited to projects where available roof area, output density and a clean all-black appearance are important considerations.
- Useful where roof space is constrained
- All-black residential appearance options
- Considered alongside shading and roof geometry
- Current models may include 500W options where suitable
Trina Solar panels
A practical residential and commercial option offering strong system-design flexibility, established manufacturer support and dual-glass module pathways.
- Suitable for many Perth roof layouts
- Residential dual-glass options
- Good balance of output, size and value
- Current ranges may include 475W options where suitable
Confirm the complete system
A panel should not be selected independently of the inverter, roof layout, mounting design, electrical supply, monitoring and future energy plans.
- Exact module model and wattage
- Product and performance warranty terms
- Approved-product status at time of design
- Compatibility with the proposed inverter
- Modelled array layout and system output
Beyond the panel datasheet
What makes a good solar panel design in Perth?
High-quality solar panels still require a suitable layout, compatible inverter and careful installation. The complete design determines how effectively the system can offset household or business electricity use.
Match production to usage
North-facing panels are not the only useful option. East and west orientations can help spread solar production across the morning and afternoon.
Model obstructions properly
Chimneys, trees and neighbouring structures can affect individual panels, strings and the most suitable inverter architecture.
Compare temperature behaviour
Panel output changes as cell temperature increases. Temperature performance should be considered alongside wattage and efficiency.
Use the available roof carefully
Module dimensions, setbacks, roof hips, vents, valleys and access requirements can be as important as the nominal panel rating.
Coordinate panels and inverter
String voltage, inverter inputs, capacity, phases and future battery compatibility must be resolved as part of one design.
Protect long-term reliability
Panel handling, mounting, cable management, roof penetrations, isolators, electrical protection and commissioning all affect the final installation.
The highest-wattage solar panels are not automatically the best choice
A slightly different panel may allow a better string design, cleaner roof layout, stronger inverter compatibility or more useful production across the day.
A clear installation pathway
From your Synergy bill to installed solar panels
Australis Solar brings the energy assessment, equipment selection, network application, installation and handover together through one local team.
Share your information
Provide your property address, recent Synergy bill, existing solar details and any battery, backup or EV charging plans.
Roof and usage modelling
We assess available roof area, orientation, shading, likely production, consumption and electrical infrastructure.
Tailored proposal
Your proposal identifies the recommended panel and inverter combination, system size, modelled output, assumptions and known installation work.
Approval and installation
Applicable applications are managed before accredited installers and licensed electricians complete, test, commission and hand over the system.
Western Australian connection and export requirements
New or changed inverter systems generally require an embedded-generation connection application. Export arrangements and buyback eligibility depend on the customer, tariff, inverter capacity, system configuration and current Western Power and Synergy requirements.
Local design and accountability

Solar panels FAQs
Practical answers about panel selection, system sizing, roof design, batteries, blackouts and WA approvals.
What are the best solar panels for a Perth home?
There is no single panel that is best for every Perth home. The appropriate choice depends on available roof area, shading, orientation, panel dimensions, system capacity, appearance, inverter compatibility, manufacturer support and budget. Australis Solar compares these factors before recommending a model.
How many solar panels do I need?
The number depends on the required system capacity and the wattage of the selected module. It must also fit within usable roof space and suit your electricity consumption, inverter design, shading and future battery or EV requirements. Panel count should therefore follow the system design rather than be selected first.
Does solar panel orientation matter in Perth?
Yes. Orientation affects when the system produces electricity. North-facing panels can provide strong overall production, while east-facing panels produce earlier and west-facing panels can better support afternoon usage. The most suitable layout depends on shading, roof space and when the property uses energy.
Will solar panels power my home during a blackout?
A standard grid-connected solar system normally shuts down during a network outage for safety. Blackout operation requires compatible inverter, battery, gateway or transfer equipment and a system specifically designed for backup. Not every battery provides whole-home backup.
Can I install solar now and add a battery later?
Often, yes. However, future battery compatibility depends on the inverter, electrical architecture, switchboard, available installation location, network requirements and the type of backup required. Planning for storage during the initial solar design can reduce avoidable changes later.
Do I need Western Power and Synergy approval?
New or changed inverter systems generally require an embedded-generation connection application. Export and buyback eligibility depend on the customer, tariff, inverter capacity and final configuration. Australis Solar manages applicable applications for accepted installation projects.
How long do solar panels last?
Modern solar panels are designed to operate for decades, but output gradually declines and product and performance warranty terms differ between models. Long-term results also depend on product quality, installation, environmental exposure, system operation and support availability.
Will solar panels eliminate my Synergy bill?
Solar can reduce grid imports, but no responsible installer can guarantee that every electricity bill will disappear. Results depend on system size, weather, shading, household usage, electricity tariffs, fixed charges, exports and whether battery storage is included.
