Renyqcitt 1000 Watt Flexible Solar Panels ETFE 2x500 Watt Solar Panels

Word of warning!!!!
Do not buy these solar panels. I couldn't figure out why my batteries weren't charging to 100% (abt. 29VDC), after "charging" all day. So something someone said on this page made me think. I went out and isolated my solar cells and tested them.

1. 2 Trina 250W tested great at around 300w while charging.
2. 2 Renogy 100W tested fantastic at 100w while charging.
3. The 2 500W tested bad at 0w, 45v

So I combine, 1 and 2 above above and i have 350w and in 2 hours my batteries are charged and i am getting around 100VDC+
Now back to load testing with a BIG ole smile.

Thanks for posting. I was just noticing these wild claims on Amazon, as I am about to power a small work/storage shed. Already have a huge system on one of my RV trailers. There are some on Amazon claiming to be Renogy panels, and claiming 400 and 600w PER panel, on that same 46 x 21 dimension! Wouldn't that be amazing! I use SunPower now, which are I believe the most efficient in the biz, and no way I could get close to that kind of production per sq ft... and out of FLEXIBLE?! I debated the $200 kit of 2 400w panels and charge controller just to screw around and see what they actually put out. Don't think I'll bother. Picked up a portable Renogy 200W setup to get me by until I piece together an affordable system for my needs. About to leave country again through for a hot minute, so not a huge priority atm. World may shit itself in the meantime anyway. Lol.
