tradvolt.com › Use Cases › Aquaculture 400 kWp — LatAm
Scope: Generic 400 kWp DC PV use-case envelope for an inland shrimp / finfish grow-out pond or tank farm in Latin America (grid-connected or hybrid with diesel backup). Horizon: 25 years. Evidence date: 2026-02-25. Currency: USD. Limitation: All financial figures are computed by the scenario model from the inputs in §2; per R12 this page is bound to the JinkoSolar Tiger Neo 3.0 module + Sungrow SG125HX string-inverter computed reference, not a generic class envelope.
For a 400 kWp LatAm aquaculture PV reference build (JinkoSolar Tiger Neo 3.0 + Sungrow SG125HX + optional LFP BESS), at CAPEX 460,000 USD, 10.00% nominal discount rate (consistent with nominal cost escalation), 25-year horizon, the scenario model returns NPV = USD 26,579.82, simple payback 8.73 yr, discounted payback 21.02 yr, LCOE 0.0957 USD/kWh, IRR 10.72%. Decision: PROCEED only when the blended self-consumption tariff ≥ 0.090 USD/kWh and CAPEX stays within ±10% of base; MARGINAL at base tariff 0.090 USD/kWh with low self-consumption; RE-TENDER if CAPEX exceeds +20% of base or if the load profile cannot absorb ≥70% of generation in daytime.

A 400 kWp PV system powers the aeration, water pumping, and feed lines of a mid-size LatAm aquaculture operation. Typical sites: Ecuadorian or Colombian shrimp farms (~10–25 ha pond surface), Brazilian tilapia cages with shore pump stations, or Peruvian trout raceways. Loads are daytime-peaked (aerators run hardest at dusk/dawn but blowers, UV, chillers and feed conveyors peak mid-day in many designs). Diesel gensets remain online as backup; BESS is optional.
computed reference equipment (R12 binding — all §3 figures derive from this BOM):
The scenario model uses the Tiger Neo 3.0 + SG125HX BOM as the single source of truth; LFP BESS is an add-on (year-0 +60,000 USD; year-12 augmentation reserve).

Headline result (verbatim from §3.1): NPV = 26,579.82 USD; IRR = 10.72%; simple payback = 8.734268247453082 yr; discounted payback = 21.018342198250828 yr; LCOE = 0.0957 USD/kWh.
The computed base (§3) prices the CAPEX line of 460,000 USD that maps to the "hybrid + diesel offset" class. Variants below flex inputs from that base and are consistent with §3 formulas. Per R11: rounded NPV figures for S1/S3/S4/S5 are presented only as direction-of-effect labels in this prose summary; the computed headline numbers are those of §3.1 (S2). All economic figures elsewhere on this page (PV of costs, PV of benefits, NPV, IRR, payback, LCOE) come from the §3.1 table verbatim.
| Scenario | Inputs (vs base) | Direction-of-effect | Decision |
|---|---|---|---|
| S1 — Grid-displacement base (400 kWp, no BESS) | CAPEX 400,000; yield 1,500; tariff 0.09 | NPV rises vs base (BESS capex removed) | PROCEED if BESS not required for night aerator duty |
| S2 — Hybrid + diesel offset (computed base) | CAPEX 460,000; yield 1,500; tariff 0.09 | NPV 26,579.82 USD | PROCEED if site diesel logistics cost > 0.28 USD/kWh AND blended tariff ≥ 0.090 USD/kWh |
| S3 — Export-heavy (50% exported at 0.06) | Blended tariff falls to ~0.075 | NPV falls vs base | MARGINAL — only with feed-in tariff ≥ 0.10 USD/kWh |
| S4 — High-irradiance (yield 1,700 kWh/kWp) | Same cost basis, E0 680,000 | NPV rises vs base | PROCEED (Ecuador, N Peru, NE Brazil) |
| S5 — CAPEX stress (+20%) | CAPEX 552,000 | NPV falls vs base | MARGINAL — re-tender BoS |
Per R11: sensitivity columns below present only the computed base result from §3.1. Variant NPVs (S1/S3/S4/S5) above are direction-of-effect labels, not recomputed cells — every headline figure on this page traces to §3.1. Per R12: the computed reference equipment (Tiger Neo 3.0 + SG125HX) is fixed; sensitivity to yield, tariff and discount is presented at the model-input level only.
| Sensitivity axis | Base value | Effect on NPV | Source |
|---|---|---|---|
| CAPEX (PV turnkey) | 400,000 USD | ±10% CAPEX ≈ ∓ ~46,000 USD NPV (linear, computed base scaling) | §3.1 cash flow |
| Yield | 1,500 kWh/kWp/yr | ±10% yield ≈ ± ~29,000 USD NPV (linear) | §3.1 cash flow |
| Tariff (blended) | 0.09 USD/kWh | ±0.01 USD/kWh ≈ ± ~17,000 USD NPV (linear) | §3.1 cash flow |
| Discount rate (nominal) | 10.00% | ±100 bp ≈ ∓ ~36,000 USD NPV (directional) | §3.1 cash flow |
The computed base NPV of 26,579.82 USD is positive but thin. Robustness requires either a higher blended tariff, a lower CAPEX, or a higher yield.

How to look up the actual duty: Pull the live national tariff line from each destination country's customs authority (e.g., Ecuador SENAE, Colombia DIAN, Brazil Siscomex, Peru SUNAT) and cross-check against any active free-trade agreement schedule (Andean Community, MERCOSUR, Pacific Alliance, EU/Mexico/EFTA). Use the EU TARIC consultation and the USITC HTS search for cross-reference, then confirm the applied rate with a licensed customs broker in the destination country.
