I think you are confusing w and wh or kw and kWh in this case.
The former post stated 5000 units which I assume to be kWh.
the 5000 represents a 24 hr consumption so the average hourly load is about 200kwh which by itself seems high unless it was a say a 75 room hotel thus allowing 2kw input power per room (24 hrs a day)and say 50kw for the remainder of the premises.
2kw input per room is probably high considering at least a COP of 3 giving 6kw refrig output.
Effective solar output of say 6hrs with ongrid feedin unit credits (or onsite storage) equals about 800kw of panels. Or 1,600, 500w panels to cover 100% load.
