How big of an area does a 400 MW solar farm need to operate?

    That depends on the efficiency of the solar cells.  To give you a gauge, I’m using the one time largest solar farm in Spain which had a peak capacity of 20MW and covered an area of 247 acres. Therefore, 20 times that capacity with the same conversion efficiency would require 4,940 acres (or about 7.7 square miles) to generate 400MW.
