Calculation method
Calculation method
Horizontal module projection (m)
Rows perpendicular to sun azimuth on level ground: pitch=Lcos(tilt)+Lsin(tilt)/tan(altitude)+allowance.
Down-sun shadow gap (m)
Rows perpendicular to sun azimuth on level ground: pitch=Lcos(tilt)+Lsin(tilt)/tan(altitude)+allowance.
Row pitch including allowance (m)
Rows perpendicular to sun azimuth on level ground: pitch=Lcos(tilt)+Lsin(tilt)/tan(altitude)+allowance.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Rows perpendicular to sun azimuth on level ground: pitch=Lcos(tilt)+Lsin(tilt)/tan(altitude)+allowance. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
