Will this solar system suffice?
I've got a Northstar Laredo SC hard side truck camper which I'd like to put solar panels on and was wondering if this system will suffice. Thanks for your input. 1. I currently have one 12v Int...

raztec,
Wire size will depend on length of run and amount of current running thru them, be it from panel to controller, or controller to bank. When running two 140w/12v panels in series, thru 50' (one way) of 6awg, to mppt cc, I see very minimal voltage loss... less than a third of one percent. In parallel/pwm, that would be 2-3x the loss, as amperage from array would be 2-3x that of series/mppt.
Thanks for this. A few more questions:
1. So should I install the two 150W panels in series or parallel?
2. For that kind of wattage wouldn't a PWM controller suffice? Or should I spend the extra and get an MPPT. The max wattage I'll ever be able to upgrade to probably 600W. But not sure with my usage and limited battery space I'll ever need that.
3. Considering a max of 10 feet to the panels, what gauge wire would I need from panels to controller and from controller to panels?
4. Is a battery monitor like the trimetric really necessary or can I simply use the morningstar controller which comes with some kind of monitor?
5. Do I have to drill holes in the roof, or can some industrial strength glue/sealant hold the panels in place?
