How many watts of solar power do I Need?
To obtain amps, we divide power in watts by voltage in volts using the same formula. A 100 amp hour battery will take five hours to charge when charged at 12 volts and 20 amps. You'll need 240 watts of solar power if you multiply 20 amps by 12 volts, thus, we propose a 300-watt solar panel or three 100-watt solar panels.
