Solar Panel Efficiency Calculator

Formula

The formula to calculate the Solar Panel Efficiency (E) is:

\[ \text{E} = \frac{\text{Pout}}{\text{Pin}} \times 100 \]

Where:

\(\text{E}\) is the solar panel efficiency
\(\text{Pout}\) is the output power of the solar panel
\(\text{Pin}\) is the total power delivered by the sun to the area of the solar panel

What is Solar Panel Efficiency?

Solar panel efficiency is the percentage of the total power delivered by the sun to the area of a solar panel that it can then convert into electrical power. This efficiency indicates how well a solar panel can convert sunlight into usable electricity.

The average solar panel efficiency is between 12-16%.

Example Calculation

Let's assume the following values:

Output Power of the Solar Panel (Pout) = 300 watts
Total Power Delivered by the Sun (Pin) = 1500 watts

Using the formula:

\[ \text{E} = \frac{300}{1500} \times 100 = 20 \]

The Solar Panel Efficiency (E) is 20%.
