A couple of questions spring to mind here.
First of all, was the concrete pad installed to give a working platform for those that may work on the Panel?.
Just because it's roughly the same size as the Compressor cylinder, shouldn't mean it was put there for the purpose.
Secondly, would the rising heat from the compressor copromise the protection in the panel?.
Also, there doesn't appear to be any supports on that orange conduit coming in from the left.
