The SoEasy ground mounting system actually lives up to its name! I really did find it "so easy" to build it without assistance. Probably the best feature is that the panel clamps simply clip onto the rail as needed instead of having to slide along a channel rom one end. The other big help is the amount of adjustability which was useful for me as I had to install the ground screw foundation manually in slightly stony ground so they could not always be positioned exactly where I wanted them to be. The design is flexible enought to accommodate deviations in the ground screws of several cm horizontally and they also give fine adjustment about 2 cm vertically to maintain perfect alignment of the panels. There were no mistakes or missing parts in my delivery, though I had to be careful not to lose any fastners as there were no spares provided either. I recommend SoEasy to any DIYer or professional looking for good price/quality system that will save time and trouble on installation.
