Solar Cell Efficiency  Summary and Q&A
TL;DR
Learn how to calculate the efficiency of a solar cell using the inputs of cell dimensions, solar intensity, and output power.
Questions & Answers
Q: How do you calculate the efficiency of a solar cell?
Solar cell efficiency can be calculated by dividing the output power of the solar cell by the input power from the sun, multiplied by 100%.
Q: What factors are needed to calculate the efficiency of a solar cell?
The factors needed are the output power of the solar cell, the dimensions of the solar cell (converted to square meters), and the solar intensity of the region.
Q: How do you convert solar cell dimensions from feet to square meters?
To convert dimensions from feet to square meters, multiply the area in square feet by 0.0929.
Q: Can solar intensity vary in different regions?
Yes, solar intensity can vary based on factors such as proximity to the equator and the presence of clouds in the sky.
Summary & Key Takeaways

Solar cell efficiency can be calculated by dividing the output power of the solar cell by the input power from the sun, multiplied by 100%.

To calculate the input power, multiply the solar intensity by the area of the solar cell (converted to square meters).

Convert the solar cell dimensions from feet or inches to square meters before calculating the input power.
