STCs apply. Be sceptical of southern yield screenshots pasted onto Far North quotes. A 6.6kW array around Cairns can generate roughly 36.3 kWh/day at ~5.5 peak sun hours before site losses. Bill savings still depend on tariff and daytime usage.
Ergon Energy manages connections for most Cairns jobs. Ask every installer to disclose export limits for your street before you pay a deposit.
