There are lots of other sizes of solar cells besides 3 X 6 inches available. You could use larger or smaller cells for your panel. Just keep a few things in mind.
The cells I settled on are 3 X 6 inches in size and are rated at roughly 3 amps. I will wire 36 of them in series to get a little over 18 volts. The result should be a panel capable of delivering almost 60 Watts of power in bright sunlight.
Getting the wax off the cells is a real pain.I would recommend buying from someone who doesn't dip their cells in wax. The first step is a bath in hot water to melt the wax and separate the cells from each other. Don't let the water boil or the bubbles will jostle the cells against each other violently. Also, boiling water may be hot enough to loosen the electrical connections on the cells. I also recommend putting the brick of cells in the water cold, and then slowly heating it up to just below boiling temperature to avoid harsh thermal shocks to the cells. Plastic tongs and spatulas come in handy for teasing the cells apart once the wax melts. Try not to pull too hard on the metal tabs or they may rip off. I found that out the hard way while trying to separate the cells. Good thing I bought extras.
- Cells of the same type all produce the same voltage no matter what size they are. So the same number of cells is always needed.
- Larger cells produce more current (Amps) and smaller cells produce less current.
- The total power your panel can produce is determined by Amps X Volts.
