Yield, revenue, and ROI — from water and light.
A pure, unit-tested model. Choose a crop and method, then watch water and solar inputs move yield, revenue, and operating cost. Every coefficient is sourced; outputs are estimates with ranges.
Stacked systems can produce many times more per m² than open field — leafy greens commonly cited at up to ~10×, with controlled-environment facilities reporting on the order of ~11.7 kg/m²/yr. Extreme multiples are best-case, not typical.

Closed-loop hydroponic and vertical systems recirculate nutrient solution and can use up to ~90% less water than conventional soil farming (recirculation commonly ~90–95%). Vertical-grown leafy greens have been reported at roughly 20–30 L of water per kg.

Insolation is expressed as kWh/m²/day (for PV sizing) or DLI in mol/m²/day (for the plant light budget). Location data is used to offset supplemental lighting in glazed/outdoor systems and to size PV that reduces energy opex.
