How it works

Finite rectangular layout fit

Compare aligned and alternating half-row-offset grids within a rectangular site using explicit rotor diameter, center spacing and edge clearance. Rank only how many whole turbines fit these two fixed grid families.

Whole columns = floor((usable width−rotor diameter−row offset)/crosswind pitch)+1; whole rows use the downwind pitch. Alternating rows use a half-pitch offset.

Compare modeled layout proposals

Compare gross annual energy, separately stated wake and other losses, and area from actual layout-model outputs. Choose the ranking objective explicitly; no loss percentage or turbine rating is invented.

Net annual kWh = gross kWh × (1−wake loss) × (1−other loss); energy density = net kWh / area ha.
