Compare like with like.

Compare user-supplied fixed-tilt and single-axis tracker inputs on an equal-capacity or equal-land basis, with transparent low, base and high tracker cases.

Method and assumptions

For each architecture, year-one net energy is entered capacity × entered specific yield × entered availability. Energy then declines by the entered degradation rate. CAPEX and annual O&M are discounted with the shared analysis horizon and discount rate.

The selected basis is checked: capacity for equal-capacity, usable land for equal-land.
Tracker low case pairs low yield with high CAPEX; base uses the base inputs; high case pairs high yield with low CAPEX.
Low/base/high are user-defined sensitivities, not probabilities or forecasts.
