TradVolt › Use Cases › Cargo-Port Solar 4 MWp (AU)
Audience: Port authority sustainability leads, EPC contractors, infrastructure funds.
Equipment: Jinko Solar Tiger Neo 580 W modules; Sungrow SG110CX string inverters; K2 Systems SingleRail / XPress mounting kit (manual rev. confirmed at RFQ).
Horizon: 20 years. Currency: AUD (A$). Region: AU coastal cargo terminals.
Evidence date: 2026-09-22. Limitation: Site-specific yields, port-DNSP connection fees, and AS/NZS 5033 certifier costs must be re-priced at RFQ.
Across the computed base case, the 4 MWp cargo-port solar system is strongly proceed: NPV = A$15,770,883, IRR = 26.83 %, simple payback ≈ 3.86 yrs, discounted payback ≈ 4.50 yrs, LCOE = A$0.1095/kWh, well below the 2026 AU commercial tariff benchmark. Figures below are the only computed numbers on this page and were produced by the scenario TCO model for the scenario described in §2.

Simple payback uses undiscounted cost and benefit; discounted payback uses the discounted net column above. CAPEX falls in Year 0; the Year-12 cost spike is the string-inverter replacement reserve.

Module DC nameplate is summed to 4,000 kWp; inverter AC nameplate is set inside the DC/AC ratio window recommended by Sungrow for the SG110CX (verify against OEM manual revision at RFQ). Torque values on clamps and rails are taken from the K2 Systems SingleRail installation instructions at RFQ; SOC, Voc and Isc limits for module string sizing follow the Jinko Tiger Neo datasheet at RFQ.
