FYSA, 130W is a bit "optimal" beyond most optimal calculations for solar panels. Normal yield is closer to 70W-95W on "ideal" conditions. I have never seen over 100W on these panels under full sunlight/no shade. Just temper your expectations for these - aka don't expect 100-130W. (Source: I have 16 of these flexible panels outside right now facing directly at the sky, unobstructed)

I have two of these taped to the roof of my travel trailer. Highest input I've gotten is 220W for both. Not too bad. I have several panels in several styles from different brands and they all are about max 85% of their rated capacity.

Eh I have some of these and on the first test I got over 110w each of them. Yes 130w is optimal but on par with other ratings. In the same light my 100w renogy flexibles got 80w.

I would agree that 100-110W would be ideal. I haven't really seen much more than 1.3k on my array (out of a theoretical max of 2080w) - whether it's configured as 16s1p or 8s2p. I could have some more losses happening at my MPPT inverter, I suppose. But even with the ~1300w "peak", that's a bit rare and still only around 80-85w from each panel, and in ideal conditions.

Just an FYI, these say 12V panels, which usually means 18V open circuit voltage. However, per the listing, these have an open circuit voltage of 24.5 and a max power voltage of 21.1. Not ideal for 12V systems unless you have an MPPT charge controller and not high enough for a 24V system unless you put multiple panels in series (I doubt anyone with a 24V system would only use 1 panel). With a 12V PWM charge controller, you'll only get ~75 watts max and you might exceed the Vmax of the charge controller.

2 of these in series would be pretty good for a portable power station that has a 50V or 7.5A input limit.

I purchased 4 of these last year...thinking about getting two more with hurricane season approaching.
