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

Replace dated hardware and network assumptions with current evidence.
Check noise, cooling, site access and operating restrictions.
Compare mining with the opportunity cost of selling electricity.

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

Hardware choice

Compare efficiency, condition and acquisition costs.

Energy allocation

Keep PV consumption and export opportunity cost visible.

Operating risk

Test market assumptions instead of treating a point estimate as a promise.

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.
