Discussion on the East-West Spacing of Photovoltaic Arrays in Mountainous Areas

The spacing between PV arrays in the E-W Direction, as the name suggests, is as shown in the figure below. It seems that there is no room for discussion, so it is often skipped. However, the actual layout process of a project in Complex terrain is not as straightforward as it seems. This is mainly due to the following two reasons: 1)The arrays are arranged according to the terrain, and as the length and width of the array's projection change, the shape of the Parallelogram also changes; 2)Traditional drawing still treats arrays as unchanging rectangles for layout. For the above item 1), to control the actual East-west spacing to a set value (such as 0.5 meters), it can be achieved through a step-by-step method. This is actually not difficult. Regarding the aforementioned point 2), it is actually the reason that complicates the issue. From a two-dimensional projection, the actual arrays…
