Indicative estimate only — not a quote. Based on EECA's ~$2,000/kW installed benchmark, a regional generation yield (PVGIS-based), grid power at about 33c/kWh and an export buyback of about 12c/kWh (as at June 2026). Your actual figures depend on your roof, shading, usage pattern, retailer rate and the system you choose. Always confirm with a qualified installer.
