You could probably calculate how far out they are by using the curve of the moon visible in the picture
Would you need to know information about the lens of the camera? A wide angle lens would make the curve look bigger.
And would make any humans standing down there smaller.
In seriousness though, assuming the solar panels are straight lines the camera’s aspect ratio could be determined from that.
is that not public knowledge?
