South Australian businesses pay some of the highest commercial electricity rates in the country, with bundled tariffs regularly exceeding 40c/kWh, confirmed by the Australian Energy Regulator's 2025-26 pricing determination . At those rates, a well-sized commercial solar system delivers payback periods of 3 to 4 years and ongoing savings for 25 years after that.
