The typical cost for a 6-6.6kW residential solar panel system in Perth ranges from $5,000 to $9,000. Most homeowners can expect to pay around $6,000 to $7,500, including installation and applicable federal rebates like Small-scale Technology Certificates (STCs). These figures reflect current market trends as of April 2025.

If adding battery storage, expect to pay $800–$1,500 per kWh installed. A standard 10kWh battery may cost $8,000–$15,000. A $5,000 battery rebate may apply for systems 10kWh or larger—though this is separate from solar panel pricing.

Perth enjoys high solar efficiency, averaging 5.34 hours of sunlight per square metre per day. This solar exposure reduces payback periods, often between 5–7 years. Combined with feed-in tariffs (typically 2–10c per kWh depending on the time), excess energy can be credited back to your bill, improving long-term savings.
