Karen, I'm running two panels on my 19' Escape and raised them up 3 inches to keep them from being shadowed by the Maxi-Fan or rear AC unit. On an overcast day I am charging very well. Although they are raised I think they blend with the trailer very well.
I also added 2 more batteries so I'm up to 4 total....and upgraded the on-board converter to fully charge the batteries when on shore power....and upgraded the solar controller to a MorningStar unit. I also installed a manual bypass switch to switch over to inverter power ( 2500watt inverter wired in). The whole system is also now temperature-compensating. Often I see 15 volts charge voltage by 9:00AM and I really run a lot of stuff of my inverter;
- 1800 watt coffee maker
- 1800 watt electric griddle
- Awning lights
- Chargers for computers, cell phones, etc,
- 2 slice toaster
- 700 watt microwave
- Portable spa (just wishful thinking!)
- Electric turkey fryer (more wishful thinking!...
Most people don't need or want all this stuff but I'm a purist...and an engineer...
