Here's a chart showing it only takes a few milliamps to go from one hand
to the other to have really bad things happen.
Your skin is a pretty good insulator. The problem is your blood is a pretty
good conductor. Your skin can be breached as low as 30V; less if it's humid
or you're wet. A string of panels in the U.S. can be up to 600V, and even in
twilight or moonlight can have hundreds of volts. You don't get "power"
from the panels in those conditions as the low amps aren't enough to
power the inverter. But as you can see from the table, it doesn't take
much current traveling hand to hand to kill you.
Amps can kill you, voltage can kill you.
Be Smart, be Safe! Please be careful around any sort of wiring and use the appropriate safety gear!
