I have a quality GSL MPPT 12amp controller placed near the battery 100AH wet deep cycle Century via 4gauge 10 metre leads..
I used to have a 120Watt folding glass panel which on a good day would output up to 7 (say 100watts at 14volts) amps and more often 6 on an inline watt/amp meter to my house battery .
I then bought what was supposed to be a 160watt flexible panel as the folding panel weighed a lot and took up lots of space below the bed in my camper.
To my dismay when I expected about 8amps max (8x14=110) out of the new panel , the most I have seen is 6 amps and generally 5 through exactly the same wiring.
I expect about 20-30% loss on the stated specs but not 40-50%!
It is apparently quite common for the specs of panels to be vastly exaggerated on Ebay. I am trying to find out the experience of others who have bought a 200watt plus panel. 10amps output is not a lot on a 200watt panel !10x14=140watts but the negative
feedback on several sites suggests that even this may be optimistic.
Simple question who has bought a 200watt flexible panel and regularly sees over 10 amps from it? My impression is that few people have any idea what the output of their solar panel is but I thought I would ask . very few (none?) Australian reviews of different brands on Google.
