It wins wherever the tariff does not pay a premium for the hours tracking produces most, or where land cost makes the wider row spacing of tracking uneconomic.<\/div>\n<\/details>\n<details>\n<summary>What tilt angle should we use?<\/summary>\n<div class=\"acc-body\">It depends on latitude, row spacing, land cost and the tariff, and it should be optimised rather than defaulted. Higher tilt increases energy at high latitude but requires wider row spacing to avoid shading, so the land cost per megawatt rises. On cheap land at moderate latitude, a steeper tilt often wins; on expensive land, lower tilt and tighter rows frequently produce a better project.<\/div>\n<\/details>\n<details>\n<summary>How do you handle variable soil across a large site?<\/summary>\n<div class=\"acc-body\">By mapping rather than averaging. Borehole results are drawn onto the layout as soil zones, and each zone receives its own foundation type and pile length schedule. Where a zone boundary is uncertain, we design a pile that spans both cases with a stated adjustment range, and we price the pre-drilling option separately so the decision stays visible.<\/div>\n<\/details>\n<details>\n<summary>Can the structure be upgraded to tracking later?<\/summary>\n<div class=\"acc-body\">Not practically. Tracking requires a different foundation layout, a torque tube, bearings and drive mountings, so the conversion cost approaches a rebuild. If tracking is a realistic future option, the time to evaluate it is before the foundation design is frozen, not after.<\/div>\n<\/details>\n<details>\n<summary>Does fixed-tilt work with bifacial modules?<\/summary>\n<div class=\"acc-body\">Yes, provided the structure keeps the module rear face clear and the rail geometry does not shade the rear surface. Bifacial gain also depends on ground albedo and mounting height, so the design should account for the specific site rather than assuming a generic uplift in yield.<\/div>\n<\/details>\n<\/div>\n<\/section>\n<section class=\"el-sec\">\n<h2 class=\"el-h\">Guides et pages d&#039;application associ\u00e9s<\/h2>\n<div class=\"el-text\">\n<p>Poursuivez avec les
