Chapter 10, Problem 37E
Interpretation Introduction

Interpretation:

The surface area of the solar cell required to light a bulb is to be calculated.

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)

Power input=Surface area × Average solar power

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.
Much of the U.S. electricity is generated in thermal generating stations that burn fossil fuels such as coal and natural gas. The use of solar-powered generating stations is expected to increase over the next decade and replace older fossil-fuel generating stations. What impact might this change have on greenhouse gas emissions?
The total power used by humans worldwide is approximately 15 TW (terawatts). Sunlight striking Earth provides 1.336 kW per square meter (assuming no clouds). The surface area of Earth is approximately 197,000,000 square miles. How much of Earth's surface would we need to cover with solar energy collectors to power the planet for use by all humans? Assume that the solar energy collectors can only convert 10 % of the available sunlight into useful power.
