my guess is that you will need at least a 60W solar panel, probably more. and you need a large battery if you want to run the Pi continuously. your tiny panels are 6V x 0.12A =0.72W, so you probably need at least 70 of those kind of panels.
oops, sorry I did not read mikerrs post with the link earlier but it is interesting to see that somebody actually is trying to power the Pi by solar panel. if I understand the text correctly, the 45W solar panel turned out not to be large enough so he doubled the panel size. and the batteries keep going bad probably from being low on charge most of the time.
