Whose prayers??? Get off your @$$ and learn how to solder!! Oops, sorry man....
When I get around to my solar power projects I'll be buying some of this stuff. Like BG said, I wonder what the resistance of the connection would be? Carbon is a great conductor but it's all the other stuff (the glue) in the way that increases resistance. It's probably only low voltage AND low current capable, which is fine for solar panels.
