Australia Backs Global Push to Double Rooftop Solar to 300 Million Homes by 2030

· Energy · Australia · Fiji

Australia has endorsed a global plan to double the number of homes with rooftop solar worldwide, from 150 million to 300 million by 2030, through the Global Rooftop Solar Declaration announced at the 2026 Pacific Pre-COP meeting in Fiji. The declaration sets a collective target rather than a binding national commitment, framing rooftop solar as a central tool for expanding clean generation at the household level. The goal implies a doubling of installed residential capacity and a correspondingly larger market for panels, inverters and installation labor over the rest of the decade. Australia, among the world's most penetrated residential solar markets, is backing the initiative as governments prepare for the next round of climate negotiations.

Why it matters：A coordinated global rooftop target signals sustained demand for distributed solar hardware and installation services, and shifts attention toward grid integration and financing in markets that are still far from saturation.

Key points

  • The target would raise the number of homes with rooftop solar from 150 million to 300 million by 2030.
  • The declaration was announced at the 2026 Pacific Pre-COP meeting in Fiji.
  • It is a collective goal rather than a binding national commitment.
