Frequently Asked Questions
How do I choose the right solar system size for my home?
The ideal system size depends on your daily energy consumption, roof orientation, and available space. Most Perth homes benefit from a 6.6kW to 10kW system. Our builder analyses your usage patterns and recommends the optimal size to maximise your savings and minimise payback time.
How much does a custom solar system cost in Perth?
As a rough guide, most Perth homes pay around $5,000–$7,500 for a 6.6 kW system or $8,000–$11,000 for a 10 kW system after the STC discount in 2026. Your price depends on system size, your roof and the components you choose. The builder provides transparent pricing upfront so you know exactly what to expect, with no pressure or obligation.
What happens after I build my system online?
Once you’ve designed your system, a Talk Energy solar consultant will review your configuration, conduct a site assessment, and provide a detailed quote. From there, installation is typically completed within two to four weeks by our SAA-accredited electricians.
Do I need a battery with my solar system?
Batteries are optional but increasingly popular in Perth. They allow you to store excess solar energy for use in the evening, reducing grid dependence. Our builder shows you the costs and benefits of adding battery storage so you can make an informed decision.
