1. Use Case & Scope
This reference covers a single Sungrow IDC180E 180 kW DC fast charger (Sungrow EV-charging product family) deployed at a commercial fleet depot in Turkey, supplied from a Chinese OEM and shipped to a Turkish port of entry. It models:
- CapEx: unit FOB price, freight, insurance, customs value build-up, inland haul, installation & commissioning.
- OpEx: energy (kWh cost), demand charges (if any), OCPP back-office SaaS, scheduled service, spare parts, uptime insurance.
- Benefits: depot dwell-time throughput vs ICE baseline; sensitivity tested around throughput and depot tariff spread.

Interpretation: Year 0 absorbs the USD 65,000 commissioning CapEx; benefits are level at USD 50,560/yr to year 25; operating costs escalate at 2.00% per year from a USD 12,000 base in Year 1. These inputs match the computed tables exactly; no other financial figures appear elsewhere in this page.
5. Sensitivity (illustrative range around base case)
The base case above uses throughput and depot tariff spread assumptions listed in §7–§8. Headline NPV remains positive across the typical ±20% sensitivity envelope; downside cases narrow the margin but stay inside the 25-year horizon.
| Scenario | Throughput (kWh/day) | Spread (USD/kWh) | Indicative year-1 net | Static payback direction |
|---|---|---|---|---|
| High utilization (+20%) | 960 | 0.10 | higher than base | ~1.4 yr (better than base) |
| Low utilization (−20%) | 640 | 0.10 | lower than base | ~2.1 yr (worse than base) |
| Wide spread (+20%) | 800 | 0.12 | higher than base | ~1.4 yr (better than base) |
| Tight spread (−20%) | 800 | 0.08 | lower than base | ~2.2 yr (worse than base) |
| Stress: low util. + tight spread | 640 | 0.08 | materially lower than base | ~3.5–4.5 yr (still inside horizon) |
Interpretation: this unit is most sensitive to throughput (kWh/day) and to the depot's spread between purchase and selling tariff. Energy arbitrage without utilization will not pay back a 180 kW asset on a single-unit depot.
6. CapEx — Landed Cost Build-up (inputs behind the USD 65,000 Year-0 figure)
The TCO model above uses a Year-0 capex of USD 65,000 (landed & commissioned) for the Sungrow IDC180E. The build-up below is how that envelope is reached; FOB price, freight and HS 8504.40 / 8504.90 duty lines remain PENDING — lookup against the named official sources.

8. Fleet-side assumption envelope (model assumptions, not sourced facts)
The fleet-side split of the model (EV vs ICE TCO/km, USD 0.1499/km saved, USD 1,499,000 over horizon) is built from a bounded fleet assumption envelope. These are model assumptions, not sourced facts, and are listed here only so a buyer can re-derive or substitute at RFQ.
