Enter the values of solar power, P_(W) and area, A_(m2) to determine the value of Solar power density, P_d(W/m2).

Solar Power Density Formula:

Solar power density (Pd) is a measure of the amount of solar power (energy per unit time) received per unit area, typically expressed in watts per square metre.

It represents how much solar energy hits a given surface area and is crucial for evaluating the efficiency and potential output of solar panels and other solar energy systems.

Higher solar power density indicates more solar energy available for conversion to electricity or heat.

Solar power density – the amount of electrical power generated per unit area of the panel.

Total power output – the total electrical power generated by the solar panel under specific conditions (usually measured under standard test conditions). A solar panel with a higher power output (P) will generally have a higher power density (Pd) as long as its area (A) remains the same.

Panel area – the physical surface area of the solar panel. If two panels have the same power output (P), the one with a smaller area (A) will have a higher power density (Pd). This is because the power is concentrated in a smaller space.

Solar power density, P_d(W/m2) in Watts per square metre is calculated by dividing the solar power, P_(W) in Watts by the area, A_(m2) in square metres over which the power is distributed.

Solar power density, P_d(W/m2)  =  P_(W) / A_(m2)

P_d(W/m2)  = solar power density in Watts per square metre, W/m².

P_(W) = solar power in Watts, W.

A_(m2) = area in square metres, m².

Solar Power Density Calculation:

1. A solar panel receives 500 watts of solar power over an area of 2 square meters. Calculate the solar power density.

Given: P_(W) = 500W, A_(m2) = 2m².

Solar power density, P_d(W/m2)  =  P_(W) / A_(m2)

P_d(W/m2)  = 500 / 2

P_d(W/m2)  = 250W/m².

2. A solar array receives 3000 watts of solar power and has a solar power density of 600 W/m². Calculate the area of the solar array.

Given: P_(W) = 3000W, P_d(W/m2)  = 600W/m².

Solar power density, P_d(W/m2)  =  P_(W) / A_(m2)

A_(m2) = P_(W) / P_d(W/m2)  

A_(m2) = 3000 / 600

A_(m2) = 5m².
