The current (in amperes, A) produced by the solar panel can be determined using Ohm's law, where the current is the power divided by the voltage: Current (A) = Power (W)/ Voltage (V). The current (in amperes, A) produced by the solar panel can be determined using Ohm's law, where the current is the power divided by the voltage: Current (A) = Power (W)/ Voltage (V). 100-watt solar panel will store 8. 3 amps in a 12v battery per hour. 400-watt solar panel will store 33. 600-watt solar panel will. . 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. Multiply the voltage by the current (in amps) to achieve the wattage. In this case, the equation is as follows: 1. The is the voltage. . Solar Panel Calculator is an online tool used in electrical engineering to estimate the total power output, solar system output voltage and current when the number of solar panel units connected in series or parallel, panel efficiency, total area and total width.
