Household solar uptake in Australia is the highest in the world, but excess energy is sold back cheaply. A peer-to-peer platform letting neighbours share battery storage credits could improve grid resilience and household returns.

Australia has the highest per-capita rooftop solar installation rate in the world, yet most households export excess generation to the grid at feed-in tariffs as low as 2-5 cents per kWh — far below retail rates. Virtual power plants and neighbourhood battery sharing schemes allow households to trade stored energy credits within a local network, keeping value in the community and reducing grid load during peak periods. The regulatory environment in most states now permits this model.
