Does an average ear have enough surface area to meet its power needs with solar power? Assume the car needs an average power of 100 kW, that average solar power is 1.0 × 10 3  W/m 2 , that the car’s surface area is 4.0 m 2 , and that solar cells are 15% efficient.

Interpretation Introduction

Interpretation:

Whether an average car has enough surface area to meet its power needs with solar power or not is to be determined.

Concept Introduction:

Power input on the solar cells is the total active area of the solar cells multiplied by solar power. The percent of the input power that is converted to output power by a solar cell is called its efficiency. Percent efficiency of a solar cell is 100 multiplied by the ratio of the power out and the power in.

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

Average solar power=Power inputSurface area

Explanation of Solution

Given information:

A car needs an average power of 100 kW.

The average solar power is 1.0×103W/m2.

The surface area of the car is 4.0 m2.

Efficiency of the solar cells is 15 %.

Power input on the solar cell is calculated as:

Powerinput=(4.0 m2×1000 Wm2)
