North-south slopes are generally tolerated more generously than east-west ones, because the tracker rotates about a north-south axis and has more freedom in that direction. Manufacturers publish permissible limits, and those limits should be applied to the surveyed surface rather than to average site slope, because local variation is what actually determines feasibility.<\/div>\n<\/details>\n<details>\n<summary>What is backtracking and why does terrain change it?<\/summary>\n<div class=\"acc-body\">Backtracking is the deliberate rotation of rows away from the sun at low sun angles to prevent one row from shading the next. On flat ground the geometry is straightforward and the algorithm is standard. On sloping ground the effective row pitch varies along the slope, so the same rotation angle that prevents shading in one place allows it in another. Terrain-following backtracking accounts for that, which is why the algorithm matters differently on sloping sites.<\/div>\n<\/details>\n<details>\n<summary>When does terrain rule out tracking?<\/summary>\n<div class=\"acc-body\">When the cost of adapting the site, through foundations, earthworks and lost density, exceeds the value of the energy gain, or when the tracker mechanical limits cannot be met at any reasonable cost. The practical approach is to map the site into zones against the tracker permissible slope and row-straightness requirements, deploy trackers where those conditions are met, and consider fixed-tilt where they are not.<\/div>\n<\/details>\n<details>\n<summary>How accurate a survey is needed?<\/summary>\n<div class=\"acc-body\">Accurate enough to resolve the undulation that affects row alignment. A coarse site-wide surface will miss the local high points that determine the deepest foundation on each row and the low points that create grading problems. A topographic survey at a resolution appropriate to the row pitch is a modest cost against the foundation and earthworks quantities it governs.<\/div>\n<\/details>\n<details>\n<summary>Does terrain affect the yield model?<\/summary>\n<div class=\"acc-body\">Yes, in two ways. The terrain-adjusted layout has a different installable density, so the capacity per hectare changes. And the shading geometry on sloping ground differs from flat ground, so backtracking performance changes as well. A yield model built on a flat-plane layout overstates both capacity and production on a sloping site.<\/div>\n<\/details>\n<\/div>\n<\/section>\n<section class=\"el-sec\">\n<h2
