Solar Panel Watts = Volts x Amps

When determining the overall wattage of a solar panel we use this simple equation:

Watts = Volts x Amps.

When building a solar panel or looking for a solar panel, you should always know the final wattage, volts, and amps that you want the solar panel to produce. Your solar panel should always use the same size and same type of solar cells as well to keep the power consistant. Larger cells produce more current, or AMPS, and smaller cells produce less current. Larger cells will produce more power, but will make your solar panel heavier, and smaller cells will keep your solar panel lighter, but it will not produce as much power as larger cells. You also do not want to mix different sized cells together because the current or AMPS of your solar panel will be limited by the smallest cell in the group - wasting the power of the larger cells. SO ONLY USE SOLAR CELLS OF THE SAME SIZE AND SIMILAR AMPS.
