Tracker projects sit within that range depending on GCR and terrain. Any figure outside it is possible, but it should be justified by the layout rather than assumed.<\/div>\n<\/details>\n<details>\n<summary>What affects capacity density most?<\/summary>\n<div class=\"acc-body\">Ground coverage ratio and module efficiency, in that order, with GCR usually the larger effect. Setbacks and access provision are third, and terrain exclusion fourth. Tilt and tracker configuration matter because they change row pitch. Together these can move land requirement per megawatt by more than 30 percent between two otherwise similar projects.<\/div>\n<\/details>\n<details>\n<summary>Should we calculate land before or after the layout?<\/summary>\n<div class=\"acc-body\">After, or at least iteratively with it. Acres per megawatt is an output of the layout, so estimating it first produces a number that the design then has to fit into, usually at a cost. The practical sequence is to establish the land constraint, design the layout against it, and then derive the density that the layout actually achieves.<\/div>\n<\/details>\n<details>\n<summary>Does a tracker use more land than fixed-tilt?<\/summary>\n<div class=\"acc-body\">It can, because trackers need straighter rows and often more spacing, and their backtracking behaviour means the row pitch is set by the rotation geometry rather than by a fixed tilt. But the effect is configuration-dependent. Where backtracking allows a tighter GCR than a fixed-tilt structure would tolerate, a tracker can match or improve on fixed-tilt density. It should be modelled, not assumed.<\/div>\n<\/details>\n<details>\n<summary>How does terrain change the land requirement?<\/summary>\n<div class=\"acc-body\">By reducing the usable area. Slopes beyond the structure tolerance, watercourses, drainage lines, protected habitats and unsuitable ground are all excluded from the developable area, and in hilly terrain those exclusions can be substantial. The consequence is that gross land area is not the number to negotiate over; the developable area after exclusions is.<\/div>\n<\/details>\n<\/div>\n<\/section>\n<section class=\"el-sec\">\n<h2
