Can't tell from their website but I really hope they're not using per-panel "solar inverters" at all. The whole ground-touching array should be DC with no electronics whatsoever (except maybe for diodes, and with no significant shadows they might not even need those).

Any inverters present should be large, few, and in their own weatherproof housings above the ground.

I think per-panel inverters are a stupid idea, especially for large utility-scale installations. Sorry if I misinterpreted your comment and you meant something else.
