Hello Erwin,
From which supplier did you buy? Are you happy and tested them?
Question to the experts of this forum:
I got some flexible panels from china, reviews are good, when I tested them I couldn't even get the Isc amperage.
My testing conditions were at noon on a full sun day, panel...
Thanks @Hedges for the long answer, appreciate.
I also was wondering how they can state 32 cells , and yeah the panel is same type as you posted in your second link. They are cut into halves.
I tested also shading, if I cover 1cell , 0 amperage.
If I put my hand above the panel, amps also...
thanks for the answers.
I have a flexible panel, brand new (at least supposed to be)
55W , dimensions 565 x 530 mm, 32 SunPower Cells.
I saw several youtube videos, one of them a guy (Julian Ilett) even in UK was getting 20w from his 20W panel . I live in northern italy would expect the sun...
Would cooler panels get you that much more power ? Like 20-30%? Looking at the IV curves, seems to me strange that a 700-800w/m2 IV curve would be higher as a 1000w/m2 one, because of cooler panels.
Plus I have tried my panels directly in the garden, directly pointing the sun, temperature...

So of course I put a load on the panel and was getting 2.5A where Isc = 3.17 A and Imp is slightly above 3A.
I would expect that under full sun, clear sky a min of 3A, is that correct? Even if the voltage is say 3Volts if I have a 1Ohm resistor.
in my test the voltage was around 14Volts with...
Hello Guys,
I got some flexible panels from china, reviews are good, when I tested them I couldn't even get the Isc amperage or Voc to the specs.
do you know a quick test to check if the panel is actually able to output the power according to the stated specifications?
I see many youtube...
