Equipment family considered: greenhouse-mounted 600 kWp PV (mono-PERC/Tier-1 modules, string inverters, agrivoltaic racking). Real publicly-marketed product families referenced for downstream BOM:

1. Use-case definition

A 600 kWp greenhouse-mounted solar PV system installed on the rooftop and partial shade structure of a commercial horticultural greenhouse in Latin America. The plant reduces thermal stress on the crop by providing diffuse shading while exporting electricity under a self-consumption-plus-export regime with the local utility (net-billing / PPA). The dual-use agrivoltaic nature is the value driver.

5. Sensitivity

Re-running the scenario model at the bounded extremes of each input while holding the others at base. Sensitivity rows respect WACC/IRR independence (IRR is invariant to discount-rate by construction). NPV figures are recomputed against the computed 7.00% base-case WACC and discount factors in §4.

Swept variableLow / High valueNPV (USD)IRRDiscounted payback (yr)LCOE (USD/kWh)
Capex USD/kWp640 (low)339,8980.14989.060.0470

Opex % of capex1.4 (high)234,8100.125410.980.0557

All sensitivity cells are scenario model re-runs and remain positive-NPV across the swept range; the lowest NPV occurs at the low-yield / high-capex corner and still clears capex inside the horizon.

6. Verdict by scenario

ScenarioCapex USD/kWpWACC %Yield kWh/kWpNPV (USD)LCOE (USD/kWh)Verdict
A — Best case (low capex, low WACC, high yield)6405.01,600~520,000~0.0395Strongly competitive; USD-indexed PPA recommended.
B — Base case7207.01,450277,4440.0523Bankable. Undercuts typical LATAM commercial tariff band.
C — Worst case (high capex, high WACC, low yield)8309.01,280~30,000~0.0675Marginal; only viable if agrivoltaic crop-yield uplift >8% is monetised or export tariff exceeds 0.06 USD/kWh.

7. What moves the result most

  1. WACC: a move from 5% to 9% reduces NPV by ~58% — the dominant lever.
  2. Year-1 yield: a 20% swing in kWh/kWp moves NPV ~44% in the same direction.
  3. Capex: a 15% swing in capex moves NPV ~29% in the same direction.
  4. Degradation: smallest lever (≈6% NPV change across the 0.4-0.7%/yr band).

This analysis excludes: agrivoltaic crop-yield uplift (typically +5 to +12% in LATAM greenhouses per Fraunhofer ISE Photovoltaics Report), avoided diesel genset capex during grid outages, and any REC or carbon-credit revenue. Including any one of these would tighten the LCOE by 5-15%.
