| Metric | Value |
|---|---|
| 5kW — daily | 27.5 kWh/day |
| 5kW — annual | 10,038 kWh/year |
Using 5.5 peak sun hours as a planning figure for Brisbane, a 5kW array can produce about 27.5 kWh/day and ~10,038 kWh/year. North vs east-west layouts, shade and inverter clipping change real results — insist on a site assessment.
Federal STCs apply (Brisbane metro typically Zone 3). QLD Battery Booster ($3,000–$4,000 context for eligible homes) can matter if you add storage. Indicative 6.6kW after STC often $5,000–$7,800. For Zone 3, MrSolar’s master table (spot $39.85 as of 2026-08-05) points to about $1,076 in STCs for a comparable residential size class. Indicative installed pricing still varies widely with roof complexity.
Smaller Fortitude Valley homes with modest daytime loads, apartments with limited roof, or households building toward a later battery often start near 5kW.
Energex handles most SEQ connections (Ergon in regional QLD). SIES applications for ≤10kW residential are routine when documentation is clean; larger or export-hungry systems need earlier DNSP dialogue. Your installer should document the pathway for a 5kW system at Fortitude Valley.
Compare three CEC-accredited quotes. Require panel/inverter models, STC pass-through, export limits, and workmanship warranty. Usually a strong case if you consume daytime power. Prioritise CEC accreditation and Energex paperwork quality over the cheapest panel sticker price.
Confirm CEC accreditation, exact product models, STC/battery subsidy line items, DNSP/export assumptions, and workmanship warranty length in writing. Compare at least three like-for-like quotes via MrSolar.
