Using 5.5 peak sun hours as a planning figure for Adelaide, a 10kW array can produce about 55.0 kWh/day and ~20,075 kWh/year. North vs east-west layouts, shade and inverter clipping change real results — insist on a site assessment.
STCs apply. SA’s Home Battery Scheme (loan-style support context) can influence battery timing. Indicative 6.6kW after STC often $4,800–$7,000 in competitive quotes. For Zone 3, MrSolar’s master table (spot $39.85 as of 2026-08-05) points to about $2,192 in STCs for a comparable residential size class. Indicative installed pricing still varies widely with roof complexity.
Tea Tree Gully homes with pools, ducted AC, EVs or high WFH loads more often land at 10kW+. Confirm SA Power Networks export and phase limits early.
SA Power Networks requires pre-approval before install on most residential jobs. Single-phase export is commonly discussed around a 10kW export ceiling historically — confirm the current rule for your NMI/street. Your installer should document the pathway for a 10kW system at Tea Tree Gully.
