Perth solar and battery guidance
Solar FAQ for Perth Homes and Businesses
This Solar FAQ answers common questions about solar panels, battery storage, blackout backup, EV charging, maintenance and system upgrades in Perth. Australis Solar is a Perth-based, WA-owned company operating since 2008. Our accredited in-house installers and licensed electricians design systems around your Synergy bill, roof, shading, energy use, backup needs and future battery or EV plans.
We review the property and your actual energy requirements before recommending a system. Savings, incentives, approvals and backup performance depend on the final design and eligibility.
Practical answers, not generic packages
Solar FAQ: what Australis Solar can help you plan
This page is for Perth homeowners, new-home builders, existing solar owners and businesses comparing new systems, storage, backup, charging or support. The correct solution depends on the property, existing equipment, usage pattern and the outcome you want to achieve.
New solar systems
Custom solar designed around your electricity use, roof area, shading, switchboard, tariff and likely daytime self-consumption.
Battery storage and backup
Storage options assessed around evening usage, existing solar production, available battery location and the circuits you want supported during an outage.
Explore solar batteriesEV charging preparation
Solar, battery and switchboard planning that accounts for charger power, charging times, supply phase and future vehicle requirements.
View EV charging optionsMaintenance and system support
Advice for monitoring issues, reduced production, inverter faults, cleaning, repairs, upgrades and ageing equipment.
Designed around the property
Solar FAQ assessment checklist
A useful recommendation needs more than a roof size and a preferred product. Australis Solar assesses how the property uses electricity, what equipment is already installed and how the system may need to change in the future.
This prevents a system being selected only because it fits a standard package size. It also helps identify switchboard, connection, backup and compatibility requirements before they become installation-day problems.
- Synergy bill and usage Daily consumption, seasonal changes, tariffs, imports and exports.
- Roof and shading Available area, orientation, pitch, obstructions and likely shade patterns.
- Existing solar equipment Panels, inverter, strings, monitoring, age, condition and compatibility.
- Switchboard and meter Supply phase, protection equipment, available space and upgrade requirements.
- Battery location Access, clearances, environmental exposure, protection and cable route.
- Backup requirements Essential circuits, larger household loads and realistic power limitations.
- EV charging goals Vehicle use, charger type, daytime charging and future electrical demand.
- WA compliance Network application, approved equipment, commissioning and connection settings.

Common Perth solar questions
Solar FAQ: clear answers before you request a design
These answers provide general guidance for Perth properties. Final system size, output, backup operation, approvals, incentives and expected savings depend on the property and approved design.
How do I choose the right solar system size for my Perth property?
The right size depends on your annual and seasonal electricity use, when you use power, usable roof area, shading, inverter limits and future battery or EV plans. Australis Solar reviews your Synergy bill and property before comparing practical system options. A larger system is not automatically the best value if the extra generation cannot be used, stored or exported under the approved connection settings.
Will my solar panels work during a blackout?
A standard grid-connected solar system normally shuts down when the grid fails, even when the sun is shining. Blackout power requires a compatible battery, inverter and backup arrangement designed to safely isolate from the grid. Depending on the system, backup may support selected circuits or more of the home, but available power is limited by the inverter, battery, gateway and circuit design.
Can I add a battery to my existing solar system?
A battery can often be added to an existing solar system, but compatibility must be checked first. Australis Solar assesses the existing inverter, solar strings, switchboard, meter, network approval, battery location and the level of backup required. The final solution may use an AC-coupled battery, a compatible hybrid system or an inverter upgrade.
How do solar rebates, battery incentives and export credits work?
Eligible solar and battery systems may receive financial support through Australian Government small-scale technology certificates, while WA schemes and Synergy export credits have separate eligibility rules. Product approval, installer accreditation, usable capacity, connection settings and application timing can affect eligibility. Incentive values and tariffs can change, so Australis Solar confirms the current assumptions in the proposal rather than guaranteeing a rebate or export return.
How long does the solar installation process take?
Timing depends on network approval, site complexity, equipment availability, meter or switchboard work and the installation schedule. A straightforward residential installation may require one or more days on site, while upgrades, batteries, backup systems and new builds can take longer. Australis Solar explains the expected sequence after reviewing the property and confirming the approved design.
Do solar panels have to face north in Perth?
No. North-facing panels can provide strong total annual production, but east- and west-facing arrays can better spread generation across the morning and afternoon. The best layout depends on roof space, shading, household usage, battery charging and any export constraints, so orientation should be modelled as part of the complete design.
Do solar panels need cleaning and maintenance?
Solar systems have no moving parts, but they still benefit from monitoring and periodic professional inspection. Cleaning is only useful when dirt, debris, bird activity or site conditions are affecting the array, and homeowners should not climb onto a roof or use high-pressure cleaning equipment. If production changes unexpectedly, arrange an assessment rather than assuming the panels simply need washing.
What should I do if my system is underperforming or showing a fault?
Start by recording the inverter or monitoring-app error message and checking whether the issue affects the whole property or only the solar system. Follow only the documented shutdown or restart procedure supplied with the system, and do not open electrical equipment. Australis Solar can review monitoring information, photos and fault details before recommending remote troubleshooting, inspection, repair or inverter replacement.
Current Western Australian context
Solar FAQ guidance on approvals, incentives and exports
WA connection rules, approved equipment lists, incentive values and electricity tariffs can change. The proposal should therefore use current information for the specific property rather than relying on an old rate or a general online estimate.
Network connection requirements
New and upgraded solar and battery systems in the South West Interconnected System must meet current Western Power and WA commissioning requirements. Existing systems may also require a new application when equipment or capacity changes.
Read the WA consumer guidanceSolar and battery incentives
Eligible systems may receive small-scale technology certificates. WA battery support has additional product, provider, capacity, application and program requirements. Eligibility should be confirmed before relying on an advertised discount.

Synergy export credits
DEBS is available to eligible customers and uses current scheme terms and buyback rates. Connection size, export settings, metering and system changes can affect eligibility, so export income should not be treated as guaranteed.

Advice for your actual property
Still have a solar or battery question?
Use the Solar FAQ as a starting point, then send Australis Solar your property address, Synergy bill and goals. We can assess the roof, usage, existing equipment, backup requirements and future EV plans before recommending suitable next steps.
Recommendations remain subject to property assessment, network approval, product compatibility and current incentive rules. Blackout backup capability varies between systems and must be included in the approved design.
