Hi Ryan,
I have actually built an A/C system and power-pack for a trucker. It
consisted of a highly efficient mini-split which draws under 400
watts. I installed a quality (Invertek) 1500 watt sine wave inverter
and 16 kWh AGM battery bank and made a low loss connection to the
alternator so it will ramp up the current.
When driving, the alternator charges the battery. When stopped, he has
up to 8 hours of very quiet cooling. Putting PV on the roof, as you
guessed, is useless unless you want to float the batteries when not in
use. You will never make enough power to run the AC. When you compare
this system to APU's, you save thousands.
A few drawbacks to consider:
1.) The added weight to the cab is about 900 lbs. I mounted the
battery bank and inverter under the bed.
2.) Loss of storage space.
3.) Main engine must run for 8 hours to fully charge the battery for
the next use.
Add a 50 amp charger and you can plug in to run A/C and keep the
battery topped off.
Good luck.
Kindest Regards,
Larry Crutcher

Wrenches i had an interesting request today. I have a nieghbor who
is an over the road truck driver and he wants air conditioning while
he sleeps. The specifics i won't bore you with. but he has seen a
"Molded panel" that fits on the roof that takes the place of the
airfoil on the cab.
Has any one seen anything like this? He really wants a pv panel on
the roof. He currently has a remote start generator onboard and we
will install a bank of deep cycle batteries and an inverter but i
question the Solar panel on the roof of the Tractor.
