Array Size Solar Panels

Enter the total amps that your solar panels will produce all together.

Array size solar panels.

Then divide the kw output by your panel s efficiency to get the estimated number of solar panels you ll need for your system. Our test system will use 205 watt solar panels. Calculate the size of your solar system. Next we take the total anticipated energy production and divide that number by the panel size in watts.

The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet.
