Most Stirling homes shortlist 5kW, 6.6kW or 10kW depending on roof area, phase supply and daytime load. Upsizing only helps if you can use or store the extra generation — unlimited export assumptions are a red flag.
Shortlist CEC-accredited designers/installers who already work Stirling and nearby suburbs. Every quote should show STC Zone 3 maths, product models on the CEC lists, export limits, and a ≥5-year workmanship warranty. Compare three written proposals via MrSolar.
