You need at least 220w worth of panel for every 1kwh you hope to collect per day.
The flexible 100 watt panels I have measure about 30x40 inches. Multiply that by at least 120 to get 5kw.
I would bet on a generator and fuel as opposed to solar panels and sun for this application.
You might just want to get a generator trailer.
All off grid solar people have a backup generator. Or at some point they kill their batteries and/or go without any power.
Cheap made in China department store panels use OCV times short circuit amps to figure their over rating.
Reputable manufacturers use working volts times working amps.
So they are not over rated nearly as badly.
