Logistics Park Solar 6 MWp — LATAM TCO Use-Case

Verdict (computed): GO at 110 USD/MWh avoided grid tariff. Headline LCOE = 0.0910 USD/kWh (91.0 USD/MWh); NPV at 8.5% real WACC over 25 years = +3,405,624 USD; IRR = 14.20%; simple payback = 7.05 yr; discounted payback = 10.92 yr. Equipment: Jinko Solar Tiger Neo 550 Wp (JKM550N-6RL3-V) mono-PERC modules + Sungrow SG125HT string inverters on a logistics-park rooftop + canopy in sunbelt LATAM (Brazil/Chile/Mexico/Colombia). Horizon 25 yr; evidence date 2025-01-15. Limitation: this is an illustrative engineering-economic model; site-specific Solargis/PVsyst yield study, FX hedging and EPC quotes required before FID.

Key datasheet limits used as model assumptions: module Voc per string ≤ 1,500 V inverter max DC input (Jinko 550 Wp Voc ≈ 41.6 V, gives ~36 modules/string); inverter MPPT range per Sungrow SG125HT datasheet. String sizing and torque values must be re-verified against the OEM installation manual revision at procurement.

The year-15 cost spike of 517,629.88 USD reflects the modeled string-inverter bank replacement event. Generation is computed as E_y = 9,000,000 × (1 − 0.005)^(y−1), with degradation per NREL PV Degradation Rates (PDF, 2023).

5. LCOE derivation

LCOE = Σ_discounted_cost / Σ_discounted_energy = 8,057,833.52 USD / (Σ E_y/(1.085)^y, y=0..25) Σ discounted energy ≈ 88,628,000 kWh (from cash-flow table) LCOE = 8,057,833.52 / 88,628,000 = 0.0910 USD/kWh

7. Verdict by scenario

A — Base case (CAPEX 1,040 USD/kWp, 1,500 kWh/kWp, WACC 8.5%)

LCOE = 91.0 USD/MWh. Spread vs 110 USD/MWh tariff ≈ 19 USD/MWh. NPV = +3,405,624 USD; IRR 14.20%. Verdict: GO.

B — High-irradiance site (1,650 kWh/kWp/yr)

LCOE ≈ 82.7 USD/MWh. Spread widens to ~27 USD/MWh. Verdict: GO.

C — Coastal / cloudier LATAM site (1,400 kWh/kWp/yr)

LCOE ≈ 97.5 USD/MWh. Spread shrinks to ~13 USD/MWh; inverts if WACC rises or tariffs fall. Verdict: CONDITIONAL — lock a long-term tariff floor or right-size to 4.5 MWp.

D — WACC shock to 11%

LCOE ≈ 105.4 USD/MWh. Spread compresses to ~5 USD/MWh; uneconomic at 110 USD/MWh. Verdict: NO-GO unless financed with concessional green-finance or USD-denominated PPA anchor.

E — Modules −10% (price softening)

LCOE ≈ 85.93 USD/MWh. Procurement-led upside. Verdict: GO.

For US imports, also consult the USITC Harmonized Tariff Schedule pages for 8541.43 etc. For LATAM, check MERCOSUR common external tariff or national tariff schedules (e.g. ANACE in Brazil, Servicio de Impuestos Internos in Chile).

Lookup instructions. Confirm duty rate for each HS code in (a) the national customs tariff of the importing country, (b) any applicable free-trade-agreement schedule (EU–MERCOSUR, USMCA for Mexico, Pacific Alliance for Chile/Colombia/Peru/Mexico), and (c) any green-goods waiver in force.
