Where do you buy solar panels?

Answer 1

You can order a solar panel system and have it installed on your roof, just as you can order solar hot water, or a rainwater tank. Some countries have government funds to assist householders to buy environmental products like these because the more people have them the lighter the load on energy supplies round the world.

Answer 2

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.
