Chinese Solar Panel Test



Testing open voltage and short current on a Sopray SR-20 and SR-60 solar panels. Both panels use monocrystalline cells. Conditions were ideal and test was 20AUG11 @ 10:00. I heard alot of trash talking on forums about Chinese panels not making claimed power. As you can see the the 20W was slightly higher on short current and the 60W was alot higher than claimed. I don’t like buying Chinese crap but buying BP, Kyocera etc. is twice the money. Time will tell if they hold up structurally(I will be going over all seams with silicone).
