Anyone have experience making their own solar panels?

[MetroMPG]

Scoping out eBay, I found a seller who deals in just the cells. IE he sells them in lots to make a full panel, and from what I can tell, it looks to be about 1/3 the cost of buying a completed panel at full retail (the cost around here, anyway, which is north of $8/watt for the panels I've looked at).

I understand soldering the tabs is the hard part. I do have soldering experience.

Just wondering if anyone has tried it? How'd it turn out? Pitfalls? Advice?
