Enter the total power generated and the total area into the calculator to determine the solar power.

Solar Power Density Formula

The following equation is used to calculate the Solar Power Density.

Pd = P / A

  • Where pd is the power density (W/m^2)
  • P is the total power generated by the area (watts)
  • A is the total area (m^2)

To calculate solar power density, divide the total power by the total area.

What is Solar Power Density?

Definition:

A solar power, also sometimes referred to as surface power density, is a measure the the total potential power output a given area can yield with the sunlight it receives.

On average, solar power has a surface density of 6.63 W/m^2.

How to Calculate Solar Power Density?

Example Problem:

The following example outlines the steps and information needed to calculate Solar Power Density.

First, determine the total power output. In this example, the solar system is able to generate 3000 watts.

Next, determine the total area covered by the system. In this case, the solar system covers an area of 10 square meters.

Finally, calculate the solar power density using the formula above:

Pd = P / A

Pd = 3000 / 10

Pd = 300 W/m^2
