Our place in the sun: Australia’s uptake of solar panels is already through the roof. How much higher could it get?

Key points

• Melbourne’s postcode 3029 has the highest number of rooftop solar installations in Australia, with over 28,000 systems installed since 2001. Australia leads the world in solar electricity generation per person, with about 36% of households having solar systems.
• The country is on track for a record year of solar installations in 2026, driven by government incentives, high electricity prices, and suitable housing designs.
• Rooftop solar now supplies nearly 14% of the country’s electricity, fundamentally changing the electricity system and reducing grid demand.
