Solar Troll here. For comparison, I have two Renogy 100w "bendable" panels that weigh 4 lbs each and are the thickness of a tarp folded once. I have them on enough wire that I can make sure they are always in sunlight and pointed at the sun.
In those conditions, I am charging with 110 watt hours every hour the sun is above the trees, 10 hours per day last week in Oregon. If my math is correct that means I got 90 ah per day, give or take.
This is on a system that requires no drilling, no mounting, is completely portable (I've been using it with my tent), and has a TCO of $500. I believe if I used an (expensive) MPPT controller the harvest would be somewhat better.
HERE'S MY POINT: Aiming is everything in Solar. I wish somebody had told me that before I mounted 600+ watts of Kyocera boat anchors to my TT roof. Oops, I wasn't going to say "boat anchors".
