Frequently Asked Questions

How much can I save with solar panels in Australia?

The average Australian household with a 6.6kW system saves between $1,500–$2,500 per year on electricity bills, depending on their state, usage patterns, and feed-in tariff rate. Systems typically pay for themselves in 4–7 years.

What is a solar feed-in tariff?

A feed-in tariff (FiT) is the rate your energy retailer pays you for excess solar electricity you export to the grid. Rates vary by state: QLD offers the highest (around 6.5c/kWh) while WA's Synergy offers around 2.25c/kWh.

How long does it take for solar panels to pay for themselves?

In Australia, a typical 6.6kW solar system costs $7,000–$10,000 installed and pays for itself in 4–7 years, depending on your state, electricity usage, and how much solar you self-consume vs export.

What size solar system do I need?

A typical Australian household uses 15–25 kWh per day. A 6.6kW system (the most popular size) generates around 26–30 kWh/day in most states, covering most household consumption. Larger households or those with EVs or pools should consider 10kW+.

Does location affect solar output?

Yes significantly. Queensland and Western Australia receive the most solar radiation (5.0–5.5 peak sun hours/day), while Tasmania and Victoria receive less (3.5–4.5 hours). This calculator uses 4.5 hours/day as the Australian average.
