I think all those 4 in a cluster are part of the "Glenrowan solar farm".  The smaller one closer to the Glenrowan Terminal station with the 66kv line running between the two is the "Glenrowan West solar farm" (Way1302629086) .  I was working on those 3 sites and it caused a bit of confusion.    I will seek some clarification from the Glenrowan Solar farm and let you know.

Thank you
