Ultra-Low-Cost Solar Could Unlock 2,600TWh per Year to Power Australia’s Green Metals Export Potential, ACAP Says

Why It Matters

The analysis shows that affordable solar can simultaneously decarbonise Australia’s economy and create a multibillion‑dollar export industry, reshaping global supply chains for renewable‑energy commodities. It signals a shift from cost‑concern to scale‑opportunity for the country’s clean‑tech sector.

Key Takeaways

• Ultra‑low‑cost solar could enable 2,600 TWh export annually
• 30‑30‑30 target aims 30% efficiency, $0.20/W cost
• 2,000 GW PV capacity could power domestic decarbonisation
• Green aluminium, steel, ammonia may reach cost parity
• ARENA invests ~$66M in solar scale‑up challenges

Pulse Analysis

Australia’s solar advantage stems from its vast, high‑irradiance landmass, but turning that resource into economic value hinges on cost. The 30‑30‑30 vision—30% panel efficiency at $0.20 per watt—represents a dramatic drop from today’s $0.50‑$0.60 per watt levels. By compressing the levelised cost of electricity below AU$20/MWh (about $13/MWh), the country can supply cheap, dispatchable power that underpins both domestic decarbonisation and large‑scale export projects.

The ACAP study links this cheap electricity to a 2,600 TWh annual export potential, primarily through green metals such as aluminium, steel and ammonia. With power costs falling below current wholesale prices, production of these commodities can achieve cost parity with fossil‑fuel‑based methods, making Australian green products competitive in global markets. This could reshape supply chains for renewable‑energy infrastructure, as overseas developers seek low‑carbon inputs for wind turbines, solar farms and electro‑fuel plants.

Policy support is already materialising. ARENA has earmarked roughly $66 million USD for its Solar Scale‑Up Challenge, $40 million USD for ultra‑low‑cost solar R&D, and $65 million USD for SunMan’s 500 MW PV module hub, all aimed at driving down costs through innovation and scale. These investments, combined with the FIRM Energy model’s integrated approach, suggest a clear pathway for Australia to transition from a raw‑material exporter to a supplier of fully decarbonised industrial goods. The next hurdle will be translating modelling insights into commercial projects that can meet the projected 2,000 GW capacity.
