A solar power plant is to be built with an average power output capacity of 2450

Question

A solar power plant is to be built with an average power output capacity of 2450 MW in a location where the average power from the sun's radiation is 200W/m^2 at the earth's surface. (Please explain all steps)

Part A.) What land area (in Km^2) must the solar collectors occupy if they are photocells with 43.0%?

Part B.) What land area (in mi^2) must the solar collectors occupy if they are photocells with 43.0%

Part C.) What land area (in Km^2) must the solar collectors occupy if they are mirrors that generate steam for a turbinegenerator unit with an overall efficiency of 20.0%?

Part D.) What land area (in mi^2) must the solar collectors occupy if they are mirrors that generate steam for a turbinegenerator until with an overall efficiency of 20.0%?

Explanation / Answer

a) total land area required in Km2 = 2450*106/(.43*200*106) Km2 = 28.49 Km2

b) total land are required in m2 = 28.49 * 106 m2

c) total land area required in Km2 = 2450*106/(.2*200*106) Km2 = 61.25 Km2

d) total land area required in m2 = 61.25 *106 m2
