1.3/7=0.1857142 Gigawatts per solar plant.

0.1857142 X 21=3.9 Gigawatts of energy that 21 solar plants would generate.

That power is enough to power 2,700,000 homes.

Well, its THREE times the number of panels, so they will generate 3 TIMES the number of GW

3 x 1.3 = 3.9 GW     It will be THREE times the number of homes too.......right?
