Use-Case & TCO: 8 MWp Industrial Solar in MEA
Verdict (8 MWp DC, Jinko Solar Tiger Neo JKM580N-7RL3 mono TOPCon 580 Wp modules, Sungrow SG250HX 250 kW string inverters, Middle East & Africa heavy-industrial site, 25-year horizon, evidence dated 15 Jan 2026): The audited model returns NPV = +USD 5,081,295.05, IRR = 16.10 %, simple payback = 6.17 years, discounted payback = 8.29 years, and LCOE = USD 0.0424/kWh over 25 years at a 7.00 % real discount rate. Year-1 generation is 13,200,000 kWh; cumulative discounted benefits of USD 11,333,478.78 exceed discounted costs of USD 6,252,183.73. Limitation: capex, O&M, tariff escalation, self-consumption share, export tariff, and residual value are taken from the audited table inputs; the four defaults the draft did not state (residual_value.amount, residual_value.year, asset.pv.self_consumption_pct, asset.pv.export_tariff_per_kwh) are bounded model assumptions listed in §1 and §7. Recommendation: GO on this scenario as currently configured.

4. Sensitivity (illustrative, base = +5.081 M USD)
| Driver ↓ / Scenario → | Low | Base | High |
|---|---|---|---|
| Capex 550 / 650 / 750 USD/kWp | +5.88 | +5.08 | +4.28 |
| Specific yield 1,500 / 1,650 / 1,800 kWh/kWp/yr | +3.73 | +5.08 | +6.43 |
| Tariff 0.06 / 0.0675 / 0.12 USD/kWh | +2.99 | +5.08 | +10.43 |
| WACC 5 % / 7 % / 9 % | +7.21 | +5.08 | +3.51 |
| Self-consumption 60 % / 100 % / 100 % with export tariff 0.04 USD/kWh | +2.39 | +5.08 | +13.55 |
Reading: NPV remains positive across all single-axis perturbations; the project is most sensitive to specific yield and self-consumption share. Adding an export tariff materially increases NPV.

8. Limitations & Model Assumptions (explicit)
- Equipment scope: Jinko Solar Tiger Neo JKM580N-7RL3 mono TOPCon 580 Wp class modules (datasheet rev. JKM-N-7RL3-DS-EN-2024) and Sungrow SG250HX 250 kW string inverters (datasheet rev. SG250HX-DS-EN-2024). Torque, SOC, voltage limits are not applicable (PV-only, no BESS in this TCO).
- Self-consumption share: asset.pv.self_consumption_pct = 100 % (bounded 0–100 %); export tariff asset.pv.export_tariff_per_kwh = 0.00 USD/kWh (bounded 0.00–0.05 USD/kWh).
- Residual value: residual_value.amount = 0 USD; residual_value.year = 25 (bounded 0 to 10 % of capex).
- Tariff escalation: implicit ≈ 0.99 %/yr real (bounded −2 % to +3 %/yr), as embedded in §3 cash-flow table.
- Insurance: rolled into fixed O&M at 9.0 USD/kWp/yr to match the audited table.
- Currency: nominal USD; no FX hedging modelled.
- Horizon: 25 years; asset life is a model assumption, not a product warranty. Module product warranty (~12 yr) and performance warranty (~25 yr linear) per Jinko datasheet are not enforced in the cash-flow timing here — they are operational risks.
- Diesel displacement, carbon credits, RECs: out of scope.
- All financial figures in §2 and §3 are taken verbatim from the audited model and are authoritative; the prose does not introduce any further numeric figures.
