Because watts is equal to amps x volts, you can calculate amps by dividing watts by volts. If you have a 100W solar panel with a maximum power voltage of 18.6V, the solar panel''s max amps will be 100/18.6, which is 5.3 amps. In real life, however, the amps produced by the solar panel will be slightly lower.
