Solar Panel Conversion Efficiency Calculator

Formula

The formula to calculate the conversion efficiency of a solar panel is:

\[ \eta = \frac{P_m}{A \times P_{in}} \]

where:

\(\eta\) is the conversion efficiency
\(P_m\) is the peak power in Watts
\(A\) is the area in cm² (calculated as length × width)
\(P_{in}\) is the incident light power per unit area (100 mW/cm²)

Definition

The conversion efficiency of a solar panel is the ratio of the electrical output of the solar cell to the incident energy in the form of sunlight. It is a measure of how effectively the solar panel converts sunlight into electricity.

Example Calculation

Let's assume the following values:

Peak Power (Pm) = 2000 W
Length = 150 cm
Width = 100 cm

Using the formula:

\[ \eta = \frac{2000}{150 \times 100 \times 100} \times 100 \approx 13.3\% \]

The Conversion Efficiency is approximately 13.3%.
