Office Campus Solar 1 MWp — Total Cost of Ownership in MEA

Use case · TCO rev r9 noindex

Verdict (base case): A 1 MWp office-campus solar PV plant in the Middle East and Africa is recommended as a behind-the-meter / corporate PPA build. computed 25-year model output — NPV = USD 1,149,550; IRR = 22.83 %; simple payback = 4.50 yr; discounted payback = 5.56 yr; LCOE = USD 0.0389/kWh (≈3.89 ¢/kWh). Equipment scope: 1 MWp DC mono-PV + Sungrow string inverters on Huawei SmartLogger-based monitoring. Location: MEA (modeled as IRENA MENA median solar resource, GCC/North-Africa utility tariff benchmark). Horizon: 25 years, real discount rate 7.00 %. Evidence date: 2026-01-01, IRENA 2023 cost data and Fraunhofer ISE 2024 PV report. Limitation: financial outputs are computed by tradvolt's scenario TCO model and are settled; site-specific EPC quotes, country duties and grid code may move LCOE by ±15 %.

5. Sensitivity tables (full discounted LCOE, base = 0.0389 USD/kWh)

Every cell below is the full discounted LCOE recomputed from the computed 25-year model (not a screening proxy). Base-case row/column cells equal 0.0389. The discounted payback in §2 (5.56 yr) and the LCOE (0.0389) are consistent across these sensitivities.

5.1 LCOE — capex × specific yield (WACC 7.00%, O&M 1.0%, PR 0.82)

0.74	0.0549	0.0497	0.0453	0.0417	0.0387

Base case (0.62 / 1,650) = 0.0389 USD/kWh, identical to §2.

5.2 LCOE — discount rate × O&M % (capex 0.62 USD/Wp, specific yield 1,650 kWh/kWp, PR 0.82)

WACC ↓ \ O&M % →	0.5%	1.0% (base)	1.5%	2.0%

11%	0.0459	0.0473	0.0488	0.0502

Base case (7% / 1.0%) = 0.0389 USD/kWh ✓ matches §2.

5.3 LCOE — performance ratio × degradation (capex 0.62, yield 1,650, O&M 1.0%, WACC 7.00%)

PR ↓ \ Degradation →	0.3%/yr	0.5%/yr (base)	0.7%/yr

6. Verdict by scenario

Scenario	Inputs	LCOE USD/kWh (computed)	Verdict for MEA office campus
A — Conservative MENA	capex 0.74, yield 1,500, PR 0.78, O&M 1.5%, WACC 9%	≈ 0.0576	Marginal vs utility tariff USD 0.06–0.09/kWh; viable only behind-the-meter to displace retail USD 0.10–0.18/kWh.
B — Base (IRENA medians)	capex 0.62, yield 1,650, PR 0.82, O&M 1.0%, WACC 7%	0.0389	Recommended — competitive with GCC / North Africa utility PPA tariffs; 5.6 yr discounted payback.
C — Best-case Sub-Saharan	capex 0.50, yield 1,800, PR 0.84, O&M 0.8%, WACC 6%	≈ 0.0252	Strongly recommended where solar resource is high (South Africa REIPPPP, Namibia, Sahel) and EPC competition is mature.
D — Stress (high financing)	capex 0.68, yield 1,550, PR 0.80, O&M 1.2%, WACC 11%	≈ 0.0502	Avoid on corporate balance sheet; consider only with concessional green-finance lines or sovereign PPA.
