Question

A solar power plant is to be built with an average power output capacity of 2250{ m MW} in a location where the average power from the sun's radiation is 210{ m{ { m W}/{ m m}}}^{ m{2}} at the earth's surface. Part A What land area (in { m{{ m km}}}^{ m{2}} ) must the solar collectors occupy if they are photocells with 40.5% ? A = { m km^2} SubmitMy AnswersGive Up Try Again; 5 attempts remaining Part B What land area (in { m{{ m mi}}}^{ m{2}} ) must the solar collectors occupy if they are photocells with 40.5% ? A = { m mi^2} SubmitMy AnswersGive Up Part C What land area (in { m{{ m km}}}^{ m{2}} ) must the solar collectors occupy if they are mirrors that generate steam for a turbinegenerator unit with an overall efficiency of 20.5% ?

A = { m mi^2}

Explanation / Answer

A) Area = 2250*10^6/(210*0.405) = 26.455 x 10^6 m^2 = 26.4655 km^2 B) 10.2143326 mi^2 C) 56.2648 km^2 D) 21.7239607 mi^2
