How to solder to solar panels.

Use Silver solder, don't get the surface too hot, for too long otherwise the conductive print on the cell will come off. And I think the tan layer it what's left when the conductive print comes off ;(

Conductive epoxy, with as long a wire overlap as possible.

Use a conductive pen.

I've never tried to solder to that?

Have used it to repair traces how ever.

Guess I'll give that a try next time, Thanks.

Thanks.

You are using flux and a large enough iron? Make sure you pre-tin all surfaces you want to mate as if you can't pre-tin them then they cannot be mated. If you can pretin them easily but they will not mate then it is most likely a heat issue. If you can't pre-tin a surface then it could be heat, flux, material, etc...

If you have lead-free solder then it has a higher melting temperature and is more difficult to use. It also does not flow as well at lower temperatures.

You see, the problem is that the material used on the back of the panel is made of something that resembles nickel.. Very hard and very shiny..

I think 950F should've been more than enough.. It didn't even touch it. It simply just puddled and rolled off.

I was able to find a spot near by where the original one was attached and its fine for now.

Suggestions were made to use conductive expoxy/conductive pen..

The pen I have and I performed an experiment.. It seems that I can solder to that just fine and it sticks to a piece of chrome I have here with the DCR better than expected.. I only needed a low temperature for that..

I'll be getting some conductive epoxy for future task..

Have a good day.

Solder to it?

fix/glue what you want to the board/panel and then complete the circuit with the pen - no solder.

or use one of those kits sold to repair rear window demister tracks / connections in cars.

simply just puddled

What the base material?

If the panel is acting as a massive thermal sink then you could be heating the solder to 950 while the panel's getting nowhere near that.

You could try pre-heating a corner with a blow torch (as long as this isn't going to destroy the panel).

Nial.

simply just puddled

When are the total retards and totally retarded suggestions in this group ever going to end!?

When you stop posting?

Youre IQ dropped 20 points the moment your sent that retarded post.

Wait! It was already that low!

The proper attachment media is electrically conductive epoxy (silver filled), just like in the IC chip bonding industry, you retarded twit.

Youre?

Think about that statement. You never were a math whiz.

No, he prefers to 'whiz' on electric fences.
