For a 300 kWp ground-mount PV system powering airport ground support equipment (GSE) chargers at a Middle East & Africa regional hub — equipped with Jinko Solar Tiger Neo N-type 580 W modules (datasheet PDF) and a Sungrow SG110CX string inverter (datasheet PDF) — the 25-year, 7.0 %-real TCO is 305,125.80 USD (PV of costs) on undiscounted lifetime costs of 371,481.81 USD, against a PV of benefits of 559,973.35 USD. NPV = 254,847.55 USD, IRR = 16.12 %, simple payback = 6.23 years, discounted payback = 8.37 years, and LCOE = 0.0552 USD/kWh. Evidence date: 2026-02-10. Limitation: all key figures are scenario model OUTPUT, not draft-computed; trade-policy and O&M escalation are bounded model assumptions, not measured site data.

A 300 kWp ground-mounted photovoltaic system provides daytime electricity to an airport GSE depot — baggage tugs, belt loaders, pushback tractors and ground power units recharged from on-site chargers. The reference site is a regional airport hub in the Middle East & Africa (MEA) region with high direct-normal irradiance, dusty ambient air, and grid backup for evening GSE charging. The PV system feeds a dedicated GSE charging sub-panel sized for ~180 kVA simultaneous draw. The reference BOM is real, marketed, currently-in-production hardware:

The year-13 cost spike of 33,424.25 USD combines the 2 %-escalated O&M line for that year with the simultaneous Sungrow SG110CX string-inverter replacement (one of three units, modelled as 0.10 USD/Wp × 300 kWp × 1,000 W/kW = 30,000 USD nominal), per IEC 61724 lifecycle guidance.
E₁ = 300 kWp × 1,650 kWh/kWp/yr = 495,000 kWh.
Capex = 300 kWp × 1,000 × 0.85 USD/Wp = 255,000 USD (year 0 cost).
Eₙ = 495,000 × (1 − 0.005)^(n−1). At year 25: 438,893.49 kWh.
O&Mₙ = 9 × 300 × (1 + 0.02)^(n−1). Year 1 = 2,700 USD; year 25 = 4,342.78 USD.
Inv₁₃ = 0.10 × 300 × 1,000 = 30,000 USD nominal, discounted to 12,449.32 USD at DF = 0.4150.
Benefitₙ = Eₙ × 0.085 USD/kWh × (1 + 0.015)^(n−1). Year 1 = 42,075.00 USD; year 25 = 60,004.27 USD. The 1.5 %/yr escalation is a bounded assumption (§2.1), not a published tariff series.
