What each round of Australia’s Solar Sunshot programme funds
ARENA allocated up to AUD 250 million to Solar Sunshot’s third round, after earlier rounds for manufacturing, feasibility work and deployment. Those round allocations sit alongside grants to specific projects such as Tindo’s production expansion.

The bars compare round allocations. Award amounts are shown separately in the table.
The first round split manufacturing and study work
ARENA gives AUD 500 million to Round 1A for manufacturing innovation covering modules, inputs and deployment systems. It allocates AUD 50 million to Round 1B for manufacturing studies, including feasibility and front-end engineering and design. The study funding can establish whether a proposal is ready for a larger investment. Source 1
Later rounds broadened the deployment scope
Round 2 allocated AUD 150 million to module inputs and deployment, including supporting equipment outside the modules themselves. ARENA gives up to AUD 250 million for Round 3, launched in October 2026, to support technologies for manufacturing and building large solar projects. Source 1 Source 3
Named awards show the difference in purpose
ARENA announced AUD 34.5 million for Tindo to scale solar PV production and AUD 11 million across feasibility work by Solquartz, Energus and Stellar. Its Round 2 launch also lists up to AUD 46 million for 5B’s manufacturing and deployment system. The grant amounts correspond to individual projects or a named group of studies. Source 2 Source 3
Budget availability does not count completed factories
A round allocation identifies funding available within programme rules. A grant announcement records support for a selected project. Production, domestic content and installed generating capacity need separate evidence from operating facilities or completed deployment. Source 1 Source 2 Source 3
