I just sketched this for a fellow.... These are Aptos 550w panels, the Waaree 580w panels are almost exactly the same size.... 45" x 90" give or take. you use Ironridge xr100 rails and their brackets and clamps. Because this is so low to the ground, it doesn't need cross bracing. So it's just a grid of 2" galvaized square tubing. 88" centers one way and alternating 60" and 30" centers the other way. My calculation says he needs 3-1/2 60lbs bags of concrete per post.

This is a 18.6kw array. In south Florida this will make about 1200kwh a month in winter and 1600kwh a month in summer.
