How to calculate the amperage of photovoltaic panels
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).
Calculate the current in amps by dividing power in watts by the voltage in volts.
Calculate the amperage: Amperage represents the current flowing through the cable, which can be calculated by dividing the solar panel’s wattage by the voltage to obtain the amps.
To calculate amps or to calculate amps from watts and voltage we use the formula from ohms law given below. Amps = Watts / Voltage.
How to use this calculator?Solar panel output: Enter the total capacity of your solar panel (Watts).Vmp: Is the operating voltage of the solar panel which you can check at the back side of your solar panel.Battery Volts: Enter the battery volts if you wanna know how many amps your battery bank is storing from the solar panels.Click the "CALCULATE" box for the result.
