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.
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/m 2. P (W) = solar power in Watts, W.
