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.
