Solar panels in large fields, mostly the early ones sound like a 405 TV set with mains ripple on the line output stage.
They chop the DC to make a set of half sine waves and then switch them to make a set of three sine waves to apply to the 11/33KV three phase drop cable on the closest pole.
They do about 1/4MW per acre on a clear sunny day.
If the stock in the warehouse turns over a couple of times before the go ahead to erect the panels comes up the technology can sometimes improve so much that things can get a bit "toasty" if the drop cable is only rated at 100A.
It was toasted copper with melted vinyl over it at this location.
