GCR, land and cable calculator

Fixed-tilt rows, two-high 425 W portrait tables. Energy comes from our pvlib sweep for two sites. The cost inputs are placeholders, not market prices: replace them with your own quotes.

Method: value per MWdc-year = energy x price - land acres x land cost - annualised cable and station cost. Land is array footprint only (module area / GCR). Cable is a square block with a central station, Manhattan routing, two conductors per string. Cooling, mismatch, ohmic cable loss, roads, MV cable and terrain are not modelled. Not a bankable yield: use a full simulation tool for design.
