A 32-watt solar panel draws approximately 2. 67 amps, depending on the voltage of the system. This calculation is based on the formula for electrical power: Power (watts) = Voltage (volts) x Current (amps). For instance, if the panel is connected to a 12-volt battery system, the current can be. . Use our solar panel amps calculator to calculate the solar panel amps or convert solar panel watts to amps. Vmp: Is the operating voltage of the solar panel which you can check at the back side of. . The Current at Maximum Power (Imp) refers to the amount of current a solar panel produces when it's operating at its maximum power output. (example, 2AC amps =20DC amp) Add 10% (22 amps) DC amps x 12v = DC watts. (22 x12 =264 watts) 264 would be entered in field # 3 Fields #6 and #12 are for how many hours you expect your equipment to run in a 24 hour period, and your. .
