Top 5 Positive Customer Reviews for panel solar
The product is much smaller than I’ve expected, very thin so be carful I have already broken one. Bad is that you get this dark color when you use solder flux. After i wiped it with Alkohol the color changed, too. Measurement looked good , i have tested one cell at 12am in the sun, and got about 768mA short-circuit and about 567mV open-circuit. It is good for projects with less space. At the moment i don’t know how to protect them from braking, maybe I will try to solder them carefully to my needs and secure them in epoxy. Don’t know if epoxy will influence the power output.
