Converting a small fan to run on solar power is actually a fairly simple process. You simply change the source of the fan's power from a wall socket to a solar panel, and as long as your fan is in direct sunlight, it'll run without a problem! To make such a conversion, you'll need a few parts from a local hobby shop, or a specialty website.
Instructions
1. Calculate the voltage of solar board required by looking for your fan's voltage on the casing of the fan itself. There should be a manufacturer's sticker on the bottom that will provide this information, or in the case of battery-powered fans you could simply add up the voltage of the batteries used to power it.
2. Mount your solar board and supercapacitor to the circuit board by threading their metal leads through the holes in the board. Twist the leads of the solar panel and supercapacitor together, positive to positive and negative to negative.
3. Apply the tip of a hot soldering iron and the end of a solder stick to the twisted leads to cement them together. Solder the leads from the solar board directly to the leads of the supercapacitor.
4. Strip the ends of your fan's power wires until you have about a1/2-inch of exposed wire. Attach and solder the fan's power wires to the connections between the supercapacitor and the solar board, positive to positive and negative to negative.
5. Attach your finished solar circuit to the stem or base of the fan with a neat application of electrician's tape. Be sure not to cover up the solar board with any tape.
