The way to read these charts is to look at Column 6 "No of hours idling". This shows how many hours the vehicle needs to be idling for the scenario in each row. So in first example, in a 10 hour shift, the vehicle would need to be idling for 5.6 hours to return home at the end of 10 hour shift and have 20% battery capacity in reserve.

Adding solar to Van is very good for Summer Work

This is same example above but with added 2 x 400W Solar

14000kWh of Lithium (1200Ah at 12V)

The Best Setup is to have a secondary Alternator which is easy to do with Sprinter V6 Diesel

In this example for a 10 hour shift, the engine only has to idle for 1.9 hours and still there is 20% battery in reserve.
