Re: best type of ballast material for solar PV array?If that is the final configuration, I don't like the way those blocks across the front are sitting. They aren't contributing anywhere near their full weight to ballasting the system; most of their weight is on the lower edge.
It looks like the ultimate position of the blocks will be resting entirely on the "shelf" built into the front edge of the structure. I think that they are just posing for their picture in this one. :-)SMA SB 3000, old BP panels. -
Re: best type of ballast material for solar PV array?
i would not just go with blocks as a slight shift could displace the blocks leaving it prone to go to oz. i am thinking of anchoring to large screws from the framework ends to the screw tops with something like metallic tow line. if not screws then metal poles driven into the ground much like tent stakes, but much stronger.
just thoughts. -

that's not the final position of blocks,
