A solar farm mounting system should be checked before the order is placed, not after the parts reach the site. The first points are panel size, installation angle, row distance, land slope, and the fixing method. If these points are unclear, even a small size mistake may slow down the whole installation team. The packing method also matters.
Long rails, posts, clamps, bolts, and connection plates should be counted and marked in a simple way. Workers on a large site do not want to open mixed bundles and search for small fittings one by one. It is also useful to confirm whether the project needs hot-dip galvanized parts, pre-galvanized parts, or another surface finish. These checks are basic, but they save time during unloading, sorting, and first-row assembly. The product should be discussed with the real working condition, not only with a catalogue name.
