Solar in Darwin

Darwin has the highest peak sun hours of any Australian capital at 5.8 hours per day, making it exceptional for solar generation. STC Zone 1 provides maximum federal rebates, and the NT offers its own Home and Business Battery Scheme with grants up to $5,000. The wet season reduces output from November–March, but annual totals are still among Australia's best.

💡 Local Tip

Darwin's cyclone season means all installations need cyclone-rated mounting. The NT government's battery scheme stacks with federal STCs, making battery storage particularly affordable here.
