hi
yes & no the cells are under glass sealed in eva but the tabs coming out if the panels carrode very fast gone in a month, i would seal them up with rtv silicone.
I also would hine them uot of the plastic frame they are to big, asy to do they are screwed together.
open circiut is 24.8 vdc
short circiut is .210 ma
power 18.8 vdc
amps .170ma
cells # 42 per panel
6 panels in parallel will give you 1.02 amps for 19.2 watts
hope this helps
lou
