Solar cell damage question

We brought a new solar array down with us, and somehow along the way it got a ding knocked in it. This happened while it was still in the cardboard and foam shipping packaging. The damage is about 3cm long and looks like the kind of thing a fork lift or claw hammer would do.

Three of the little silver wires or conductors are severed. Any idea how this would affect the overall array? this is a 120 watt array.

Re: Solar cell damage question

Totally depends on where in the wiring pattern the cuts are. Could knock out a couple of amps or could kill the whole panel.

Can you do a temporary hookup to see what output you get? That would be my solution. Anything else I think would be a WAG.

Don't ask if you can't handle it

based on my experience with bird poop on my panel, your 120W panel is now 60W

Re: Solar cell damage question

I'm wondering what would happen if I tried to do some micro soldering surgery there and connected those three lands back together.

At this point you probably have nothing to lose so give it a go. But just in case, test the panels first just to see what you've got.
