For many Perth homes, yes, especially where evening electricity use is high or tariffs vary through the day. A battery lets you store daytime solar and use it at night instead of buying grid power. Whether it pays off depends on your usage, roof, and plan, which is why we assess your bills before recommending a package sized to your household rather than a one-size-fits-all system. Rebates can improve the numbers: eligible systems attract STCs on the solar panels, and battery installs may qualify under the federal Cheaper Home Batteries Program and the WA Residential Battery Scheme.
System size comes down to how much power you use, when you use it, and how much roof space you have. We review recent electricity bills and daily patterns to size the panel array and battery capacity together. The aim is a package that covers your realistic demand without paying for storage you won’t use, so both the panels and battery are scaled to your actual consumption. Common combinations in Perth pair a 6.6kW or 10kW solar system with a battery sized in kWh to your evening use.
Often yes, though it depends on your existing inverter. Some setups need a hybrid inverter or a separate battery inverter to work with storage. During assessment we check what you have and confirm whether your current system is compatible or what needs changing. If you’re planning from scratch, a combined package avoids these mismatches entirely by pairing everything from day one.
Most home installations are completed within a single day once approvals are in place. The panels, battery, and inverter are mounted and wired, then the system is tested and commissioned. Larger or more complex jobs can take longer. Before that, the design and grid connection approvals stage takes some time, so the whole process from first contact to switch-on usually spans a few weeks.
Only if your package includes a backup configuration. A standard grid-connected battery shuts down during an outage for safety unless it’s set up with backup circuits. We can wire selected essentials like lighting, the fridge, and internet to keep running on stored energy. Let us know this matters to you during the assessment so it’s built into the design from the start.
These systems need little day-to-day attention. Panels benefit from occasional cleaning to clear dust and bird droppings, and the monitoring app lets you spot any drop in output early. The battery and inverter are largely self-managing. If you notice usage or generation looking off, get in touch and we can review it. Simple aftercare keeps performance steady across Perth’s hot, dusty summers.
Cost depends on the size of the solar system in kW, the battery capacity in kWh, the type of inverter, and the condition of your roof and switchboard. Single-storey and double-storey homes differ in access and labour, and backup wiring adds work if you want it. We size the package to your usage first, then provide a written quote.
