One thing, you will not be able to run an a/c with enough BTU's to cool your van on batteries, even with solar. You are going to need a generator, and at least a 9,000 BTU a/c and then your only looking at 10 to 15 degrees cooling below outside temps. As for sizing a generator, double the BTU's of the a/c to get the gen-set size. So in this case you would need a 2,000 watt generator to start, and run the a/c.
Vans, do to all the glass, metal body, air holes, are the hardest type of RV to cool.
Check out the much larger Sprinter based E-Trek at roadtrek.com under models.
They are using an all electric configuration including heat, water heating, cooking, and air conditioning all running on batteries and solar.
