Why

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

A DC nameplate uplift does not establish structural fit, AC capacity or permission to change the supported plant.

Report copy is presented in the selected language where available; some technical labels remain in English. Figures use the CZ edition’s CZK convention.

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 as-built dimensions, mounting compatibility and structural loading.
  • Replace screening costs with module, inverter and installation quotations.
  • Review tariff, grid and lender conditions before changing the plant.
CONCEPT PACKAGE · ENGINEER VERIFICATION REQUIRED

Engineering handoff package

The sample package contains a functional concept SLD built from explicit synthetic assumptions. It is editable and traceable, but it is not for construction and does not invent protection, cable, earthing or utility approvals.

  • Concept single-line diagram · PDF, SVG and editable DXF
  • Equipment, feeder, evidence and information-required schedules · XLSX and CSV
  • Design basis, saved decision brief and exact result snapshot · PDF and JSON
  • Checksummed manifest and package lineage · JSON

Built for review and continuation in the customer’s engineering workflow.

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

Replacement layout

Compare replacement modules with the existing arrangement.

Lost and added generation

Include downtime and the existing production baseline.

End-of-life economics

Connect removed equipment and recycling assumptions to the investment case.

Calculation basis

Generated offline with PV8 engine code. No customer information or live provider response is included. Financial figures use CZK. Rebuild recipe: scripts/build_public_sample_snapshots.py.
