Trackers run lower in structure weight per megawatt but add drives and controls. The number is only meaningful when the design wind speed and the structure configuration are stated alongside it.<\/div>\n<\/details>\n<details>\n<summary>Where does avoidable steel usually come from?<\/summary>\n<div class=\"acc-body\">Conservative load assumptions first, particularly where a wind speed or terrain category is applied more severely than the applicable code requires. Redundant bracing and over-specified connections second. Section selection against catalogue sizes rather than against the governing load case third. In combination these can account for a meaningful share of tonnage on a structure that has not been reviewed.<\/div>\n<\/details>\n<details>\n<summary>Can we reduce steel without increasing risk?<\/summary>\n<div class=\"acc-body\">Yes, if the reduction is verified across the whole system. The risk is that a saving in the structure becomes a cost in the foundation or a problem in service, which happens when the optimisation is performed on the members alone. The discipline is to confirm the governing load case, optimise the members against it, and then check that foundation demand, deflection and module compatibility remain satisfied.<\/div>\n<\/details>\n<details>\n<summary>Does a lighter structure always cost less?<\/summary>\n<div class=\"acc-body\">Not necessarily. Lighter members may require more of them, or more foundation capacity, or a slower installation. The relevant figure is project cost rather than structure weight, and a design that adds a little steel to reduce foundation demand or speed up installation can be cheaper overall. Steel consumption is a useful indicator, but it is not the objective.<\/div>\n<\/details>\n<details>\n<summary>How does wind zone affect tonnage?<\/summary>\n<div class=\"acc-body\">Directly and substantially, because the uplift and lateral loads that size the structure scale with the square of the wind speed. A structure designed for a high wind site carries more steel for the same span and module format than one designed for a low wind site, and the difference can be large. This is why tonnage benchmarks should always state the design wind speed they assume.<\/div>\n<\/details>\n<\/div>\n<\/section>\n<section class=\"el-sec\">\n<h2 class=\"el-h\">Gu\u00edas y
