Looks like a Microwave Directional Flat Panel Antennas for point-to-point comms, 2.4 GHz and 5 GHz.
Looks like the solar array took a direct hit from a huge hailstone or somebody maliciously hitting it with a rock.
Why the white top 1/3 of the pole? Why the excess mast height?
Pole is embedded in concrete. Must have taken several 40 or 50 pound bags of concrete plus a lot of water to mix the concrete. Not an easy task. The soil is probably very thin there and you hit bedrock quickly. Not easy to embed a steel pole in bedrock.
Guy wires are attached to bolts embedded in rock. That required drilling holes and epoxying bolts in.
Odd there are no markings or instructions on the box.
It looks to be bolted to a granite boulder.🤔
