Wet-season cloud and intense UV/heat require temperature-aware design. Cyclone region mounting is not optional marketing fluff.

Excellent generation if the structure is engineered correctly. Cheap non-compliant mounting is the fastest way to waste Darwin’s sun advantage. Higher STC zones can improve the upfront discount versus southern capitals. NT battery scheme context may apply for storage. Indicative 6.6kW after STC often $5,000–$7,500 before cyclone-spec extras. A typical 6.6kW system in STC Zone 2 currently points to about $1,594 in STCs (spot $39.85 as of 2026-08-05). A 6.6kW array around Darwin can generate roughly 40.9 kWh/day (~14,936 kWh/year) at 6.2 peak sun hours before site losses. Bill savings still depend on your tariff and when you use power — get three written quotes before you decide.
Power and Water Corporation assesses capacity. Jacana Energy FiT context (often cited around 8.3c/kWh for eligible arrangements) still usually loses to self-consumption math. Your installer should name the DNSP (Power and Water Corporation) on the quote and explain export limits for your street. If they cannot, treat the proposal as incomplete.
Use these as planning ranges for Darwin at about 6.2 peak sun hours/day. Orientation, shade and inverter clipping will move real results.

CEC-accredited installation remains mandatory for STC eligibility.
Palmerston, northern suburbs and rural blocks differ in vegetation and exposure. Alice Springs is a different climate and logistics problem — treat it as its own market. MrSolar matches you with CEC-accredited installers who already work these areas — not a single national call centre reading a script.
Shortlist CEC-accredited designers/installers familiar with Power and Water Corporation. Every quote should show STC pass-through for Zone 2, export limits, CEC-listed products, and a ≥5-year workmanship warranty. Compare at least three proposals.
