Mind boggling20MW = 20,000,000 watts = 40,000 solar panels at 500watts each.
The world's largest rooftop solar installation will cover an area of 100,000 square meters (1,076,391 square feet). That's bigger than 10 American football fields. It will be made up of around 40,000 solar panels, and it's expected to have a total output of around 22 megawatts (MW) when it comes online in January 2025.
