Land usage of photovoltaic (PV) farms. Mathematical models and calculation examples1 Scope This document is aimed at building mathematical models for calculation of the distance between arrays, to farthest avoid shading and reasonably reduce the land usage of PV farms. In general, there will be longest south north shading on the day of the winter solstice. The boundary condition to calculate the south north (S N) distance between PV arrays used in this document is based on winter solstice. The longest east west (E W) shading is on
