For a toy:
Look on E-Bay if you are wanting individual solar cells, or a small 12V panel.
A typical silicone cell should put about 1/2 volt per cell. Solder several in series to increase the voltage.
Another thing you might look at are solar lights at your favorite department store or home improvement store. Their cells should be wired to put out around 2 or 4 volts (1 or 2 batteries in series).
For a large boat:
Also consider E-Bay. You can get larger panels as you may require. Flat single cell silicone will put out the highest power. Flexible panels will conform to contours better, but be less durable and put out less power. A charge controller and MPPT may be hepful.
