Good idea about cutting them, I did not think of that, however I have a dremmell or small hobby electric drill, and I have a thin disc to cut through plastic etc.
Do you think I could cut those thin cells in a straight line or wont work ?
How would you cut them ??

i have a solar panel from an old garden light that has 8 peaces in series that produces 4 volts to charge 2 1.2volt batterys in series so cutting them down works yes i guess it is knowing how much to cut them down
it looks like they kep the solder joint in the middle and cut from each side.
i think the hard part will be getting them the right size
the dremal should work well i guess if you mount the dremal at the side of a peace of would you can run the panals along like a bench saw works you can get stright cuts every time

i would start by cutting 1 cell into 3 leaveing the 2 tabbing area there fo joining the panels this should give you about 1.1 maybe 1.2 amp per panel with losses of the glass etc that should work out right
maybe a chaep table top tile saw
i just googles and found this hope it helps http://www.youtube.com/watch?v=wAscY5fFnNA

Hey, make it easier and just try taping over part of the cell using electrical tape.  This way is not permanent and can be readily adjusted again and again.

that a very good idea pirate i hadent thoght of that
i wish i was as lucky as you was with them nife batterys they would of been ideal
