Myth that solar energy uses too much space l.jpg

Myth that Solar Energy Uses too Much Space

Lake Mead formed by Hoover Dam has an area of 640 km2. The dam has a capacity of 2,080 MW. If the same area was covered with 15% efficient solar modules, the peak solar output at noon could be at least 60,000 MW!

This includes a large margin for DC-AC inverter loss and the spacing between PV array rows
