ILLUSTRATIVE SCREENING

Test two 150 kW chargers against demand, capital cost and the separate import-rights question.

What this scenario establishes

An annual model is included in this frozen calculation. Its tax basis and assumptions must be reviewed before use.

Amounts are in EUR. Export capacity is not evidence of an import right. Other routes are alternatives, not additive revenue promises.

Illustrative inputs

Synthetic 4 MWp plant: 16,000 modules × 250 Wp.
4,400 MWh/year generation and 8 ha site area are illustrative inputs.
No grid import agreement, customer contract or surveyed layout is supplied.

Three next steps

Confirm fleet demand or a credible utilisation study.
Confirm import rights and connection works; an export agreement is not enough.
Obtain charger, civil works and electrical installation quotations.

Use this example to see the decision process. Your own result depends on your plant, assumptions and evidence; it is not a financing approval.

Explore this route in PV8

Charging layout

Place the hub, check access and account for displaced PV.

Energy supply

Compare PV, grid and storage contributions.

Financial assumptions

Change utilisation, customer prices and the complete cost stack.

Calculation basis and frozen source

Generated offline with PV8 engine code. No customer information or live provider response is included. Raw reference inputs retain their source currencies, such as USD mining assumptions; financial figures above use EUR. Rebuild recipe: scripts/build_public_sample_snapshots.py.
