Do you want my advice regarding what type of vehicle to get?

Get a box truck/moving truck, with an access door from the box that goes into the cab of the truck, for easy access

Lay your solar panels flat on the roof.. forget about tilting them towards the sun.. just leave them laying flat. Also, in most cases you don't really need a "charge controller"... Just wire the panels directly to your battery or batteries, connect a digital volt meter... It's totally cool if your panels produce a voltage of up near fifteen volts.. and even instead of a cutoff switch just use alligator clips and disconnect at your leisure..

Remember, the charge controller does use electricity... So eliminate that bottleneck.

I once left two solar panels connected to a single car battery for two months.. the voltage was at 12.9 volts.. and it was a very strong charge.

Anyways, the box van looks industrial and more secure against break INS..

I wonder if the prison will allow me to have some solar panels in my prison cell. I could pump the juice back into the grid and I could parlay that money into my new heroin and cocaine and extortion business.

I am gonna be rich and I might buy a Tesla while I am incarcerated.

I am so entrepreneury.
