Solar Panel Glass

how to attach wires to glass Solar Panel?
K I’m a newbie, but I bought four of the panels on this page. http://www.goldmine-elec-products.com/prodinfo.asp?number=G16390
So far i’ve soldered tabs to two panels. My problem now is: I can’t get the 18 gauge wires to stay on the very small tabs. Help!! I’ve tried soldering the wire to the tabs- no luck. Now i’ve tried to crimp connectors to the wire. (they seem good, but how should I attach the connectors to the tabs?) I’m disabled, but I have a clip on a steel holder to hold the solder in place while I solder. I’m even thinking aligator clips might work, but I’d love your input before I shell out even more$$
God Bless You (note i’m just making a small charger)
go to radio shack they have all the right connectors for you . i guess youre connecting 2 different size wires together. without me seeing exactly the wires its hard to tell. youll get what you need to do the job the right way
