Chapter 10, Problem 28E
Interpretation Introduction

Interpretation:

The power produced by the given PV cells is to be determined.

Concept Introduction:

Power input on a PV cell is the total active area of the PV cell multiplied by the solar power.

The percent of the input power that is converted into the output power by a PV cell is called its efficiency.

Percent efficiency of a PVcell is 100 multiplied by the ratio of power out and power in.

The expression is as follows:

Percent efficiency=Power outPower in×100 …… (1)

In 2008 the approximate energy consumption for the entire population of earth for an entire year was 4.74x10^20 joules. The sun's energy striking the earth is orders of magnitude greater than this...taking the whole surface aea of the earth for an entire year, there is approximately 1.33x 10^16 joules/miles striking the earth's surface per year. if a solar panel was 100% efficient, approximately how big would the surface area (with units of a mile) of the solar panel have to be to meet the energy needs of the people living on earth?
3. Which of the following statements is an argument against using renewable energy? O They will run out O They produce pollution O You only need a small amount to produce a lot of energy O The technology needed is expensive
Consider a cloudless day in which the sun shines down across the united states. if 2659 KJ of energy reaches a square meter (m^2) of the united states in one hour, how much total solar energy reaches the entire united states per hour? the entire area of the united states is 9,158.960 km^2.
