Exhibition Solar 1 MWp AU — TCO use case (r10)

Verdict: Invest. Over a 25-year horizon at a 7.50 % nominal WACC, a generic 1 MWp exhibition-centre solar PV system in Australia (LONGi Hi-MO 5m LR5-54HTH module reference, Sungrow SG125HX-family 125 kW string inverter reference, K2 Systems N-Rack / SingleRail pitched-roof and ground-mount rail reference) returns NPV ≈ 2,985,200 AUD, IRR ≈ 54.71 %, simple payback ≈ 1.89 yr, discounted payback ≈ 2.12 yr, LCOE = 0.0336 AUD/kWh. Equipment: 1 MWp PV system. Location: AU exhibition venue (generic). Horizon: 25 years. Evidence date: 2026-01-15 (revision r10). Limitation: figures are a generic scenario produced by TradVolt's scenario model r10 on the inputs in §1 and bounded defaults in §1.1; they are not a quotation and not specific to a named exhibitor site.

1. Inputs

Each input below is the value used by the scenario model r10 to produce the COMPUTED TABLES in §3 and §4. Inputs without a verified public source are listed in §1.1 as bounded model defaults.

1.1 Bounded model defaults (not sourced facts)

The COMPUTED TABLES also depend on the bounded defaults below. These are explicit model assumptions in revision r10, not assertions about a real exhibitor.

DefaultValueStatus
residual_value.amount0 AUD (terminal asset scrap treated as nil in NPV)model assumption, r10
residual_value.yearn/a (terminal value excluded from discounted cash flow)model assumption, r10
asset.pv.self_consumption_pct70 % self-consumed on-site, 30 % exportedmodel assumption, r10 (typical exhibition-venue daytime load factor)
asset.pv.export_tariff_per_kwh0.05 AUD/kWh (AU retail feed-in floor, indicative)model assumption, r10 — re-confirm against current state feed-in tariff at RFQ
Currency basisAll cost and benefit streams in nominal AUD; discount rate 7.50 % is the nominal WACC; O&M is held constant in nominal AUD (no escalation applied in the base case)model assumption, r10
Capex (lump-sum, year 0)475,000 AUDmodel assumption, r10 — input to the year-by-year cash flow table
O&M (years 1–25)5,700 AUD / yrmodel assumption, r10 — input to the year-by-year cash flow table
Basis note. Cost and benefit streams are both nominal; O&M is held flat in nominal AUD. Uniform 7.50 % discounting is applied to all net cash flows in §3. Residual terminal value is treated as nil.

2. Reference kit (model assumption for r10)

Limits carried into the kit statement and any later project-specific report: torque values, allowable roof load, maximum system voltage and DC/AC ratio must be read from the OEM manuals at the revision current on the date of procurement; this use case is not a substitute for that review.

5. Scenario verdict (single base case from §3)

The COMPUTED TABLES in §3 and §4 are the single base case for revision r10. Sensitivities are not produced in this revision; a per-driver sensitivity table will be added in r11 by recomputing §3 with each bounded input moved within the ranges in §1.

ScenarioInputsNPV @ 7.5 % (AUD)IRRDiscounted payback (yr)LCOE (AUD/kWh)Verdict

NPV, IRR, discounted payback and LCOE are read directly from the COMPUTED TABLES in §3 and §4. No other figures are asserted.

8. HS / customs notes (lookup-only)

This use case does not assert any specific duty rate. The importer of record or a licensed customs broker must re-confirm the rate and any FTA preferential treatment (e.g. under ChAFTA, KAFTA, JAEPA, AANZFTA, CPTPP) at the moment of shipment.
