Portable Solar Panels
Looks like Solarblvd.com has a few of these ready to go with built in charger controllers. They have 100, 120, and 160W. 160W for $249

I have 2 panels in parallel, 1 90 watt, and 1 100 watt, and I have the same controller as the one above, the 15 amp model. I have seen 10.8 amps many times, and peek at 11 amps a couple times. This shown on a digital ammeter w/ 50 amp shunt, placed between the controller and the batteries.
When the controller led display goes into blinking mode, it is entering float mode, and 100% soc.
So, with your numbers, not knowing the spec of your panels for VSC and ISC Amps... 5.4 Amps is pretty good per 100 watts, and 5.5 Amps per 100 watts is outstanding.... 5.5 x 1.2 = 6.6 Amps. I can't complain then, at 6.32 Amps, with it being late October and the sun being kind of low on the sky with not a lot of ambient light from the sky also, with the sun somewhat low on the horizon. Guess I am right in the ballpark for what I should anticipate/expect, for amps, when it comes to PWM control chargers. Actually, for 120W, I think these 120 w portable suitcase panels from Solar Blvd are pretty damn efficient in this set up. 5 or 6 hours should be plenty of charging time, enough to go easy on the generator.. use it first thing in the morning, then crank it on again the last hour before bed time.
