You'll have a tough time solar powering one of these micros. Solar cells come in 2 varieties basically. High current, low voltage (crystaline) and high voltage low current (amorphous). If you have a cell that generates 3 VDC or so, I'd bet it puts out very little current. Probably in the double digit miliamp range. If it puts out .5 VDC or so, it probably has current in the 3 digit miliamp range. Niether of which is enough to power an induction load like these power hungry micro motors. You need 1.5 volts at 1-200 mA to do the job. I have some special cells that are rated at .5 VDC and put out about 300 mA in full sun. Three of these in series would be ample to run a micro. The cells are roughly 1" by 3", so I could form them into a 3" square. Problem is they are very special cells scrapped from a NASA satellite program. I could never replace them. I've seen similar cells sold on the net for 20-30 dollars each. But, they aren't as good. Even with the lesser cells 60-90 dollars is a bit steep to solarize a 20 dollar micro. It can be done. But, it would be expensive.
