More precisely, the efficiency of the converter is calculated by dividing the output power (Pout) by its input power (Pin). The Greek symbol Eta “η” is usually used to represent “Efficiency.” Here is the formula for determining a power converter’s Efficiency (η).

Power - Conversion. Power: In physics, power is the rate at which energy is used, transferred, or transformed. The SI unit of power is the watt (symbol W, in honor of James Watt who is the eighteenth-century developer of the steam engine).

The conversion efficiency is the ratio input power to output power. The formula is: Conversion efficiency = (output power ÷ input power) x 100%. The higher the conversion efficiency is, the more energy will be saved and devices can be fully charged faster than a common one if in the same time.

When applied to solar energy conversion systems, efficiency of solar energy conversion (η) is defined as the ratio of the useful output power (delivered by the conversion device) to the incident power (of the solar radiation): What can we learn from efficiency analysis?
