The document discusses two ground mounting racking solutions from Chiko Solar for a 1.5MW PV project. Option 1 is the S-2V system, which uses hot-dip galvanized steel, has a 35 degree inclination, and is certified to AS/NZ 1170.2 standards. It can accommodate 60 and 72-cell portrait-oriented modules. Option 2 is the A-1V system, which uses aluminum, has a 35 degree inclination, and was designed for larger landscape arrays but is not suitable for a two-row portrait configuration due to its heavy-duty construction.
