ILLUSTRATIVE SCREENING

Size a screening electrolyser against a modelled solar profile; production does not establish an off-take market.

What this scenario establishes

This example does not establish a complete annual investment model. Required inputs remain visible in your workspace.

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 a buyer, product specification and delivery terms.
Obtain a dated electrolyser package quotation and utility requirements.
Verify water rights, permitting and applicable renewable-hydrogen rules.

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

Energy conversion

Review production, operating hours and minimum load.

Site interfaces

Screen water, cooling, power and space needs.

Cost and off-take

Test assumptions before committing to a vendor or buyer.

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.
