Solar in Elizabeth — What You Need to Know
Elizabeth was Australia's first planned satellite city, built by the South Australian Housing Trust from 1955 to house workers at the Elizabeth Elizabeth Motor Company (later Holden) plant. The closure of manufacturing has left a community characterised by high electricity usage (large 1950s–60s Housing Trust homes with minimal insulation), relatively low incomes, and consequently very high electricity bills. This combination creates paradoxically outstanding solar economics: with SA's highest grid electricity rates at 38c/kWh and bills averaging $3,200/year, even a modest 6.6kW system saves $2,100 annually — the best ROI in Adelaide. SA Housing Trust has been progressively retrofitting solar across its Elizabeth housing stock, and the state government's Solar for All initiative has prioritised the suburb for subsidised installations. The social norm effect is powerful here: Elizabeth streets with early solar adoption show 4x higher uptake on neighbouring properties within 12 months.
