Irrigation and water resilience

PV8 demonstration solar plant, HR · 4 MWp · synthetic inputs

ILLUSTRATIVE SCREENING

Match an illustrative pumping requirement to solar production; water demand and abstraction rights remain separate questions.

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 crop or scheme demand and the required pumping head.
Verify abstraction rights and drought restrictions.
Review pump scheduling, water storage and delivery costs with the operator.

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

Water resilience

Keep theoretical service capacity separate from rights and actual demand.

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.
