# Solar Panel Amps Calculator

Use our solar panel amps calculator to calculate the solar panel amps or convert solar panel watts to amps.

### How To Use This Calculator?

1. Solar panel output: Enter the total capacity of your solar panel (Watts).
2. Vmp: Is the operating voltage of the solar panel which you can check at the back side of your solar panel.
3. Battery Volts: Enter the battery volts if you wanna know how many amps your battery bank is storing from the solar panels.

## Some Key Points Before You Leave

We usually measure or convert the watts into amps of solar panels to figure out how much current (amps) is being stored in the battery.

Or we measure the amperage of the solar panel output, to select the wire size from solar panels to the charge controller.

So if your goal is to figure out how many amps are being stored in the battery then enter the voltage of your battery (for example 12 for a 12v battery).

### 200-Watt Solar Panel How Many Amps?

• Solar panel size: 200 watt
• Vmp (operating volts): 22.6 volts

## How Do I Calculate Solar Panel Amps?

To calculate the amps from watts use this formula.

Amps = Watts ÷ volts

## Solar Panel Amps (12v, 24v, 48v)

### Summary

• 100-watt solar panel will store 8.3 amps in a 12v battery per hour.
• 300-watt solar panel will store 25 amps in a 12v battery per hour.
• 400-watt solar panel will store 33.3 amps in a 12v battery per hour.
• 500-watt solar panel will store 41.6 amps in a 12v battery per hour.
• 600-watt solar panel will store 50 amps in a 12v battery per hour.
