What's the proper calculation for the question?

Question

The sun shines on a square meter at a certain location on the earth's surface. The average daily energy received from the sun at this location is 4.5 kilowatt-hours. What calculation would give the approximate energy per square foot?

Answer 1

First, multiply the rate of energy by 24 hours in a day to get how much energy the area gets in a day.

4.5 kW/hr*24 hrs=108 kW

Then convert 1 m^2 to ft^2.

1m^2*(1 ft^2/0.0929 m^2)=10.76 ft^2

Then divide total energy by square feet

108 kW/10.76 ft^2=10.03 kW/ft^2

Answer 2

1 m = 3.28084 ft

1 m² = 10.76391111 ft²

4.5 / 10.76391111 = 0.418063653 kwh / ft²
