How many solar panels would it take to power the US Elon? “If you wanted to power the entire U.S. with solar panels, it would take a fairly small corner of Nevada or Texas or Utah; you only need about 100 miles by 100 miles of solar panels to power the entire United States,” Musk said.
How big of a solar farm is needed to power the US? According to a report from the National Renewable Energy Laboratory, roughly 22,000 square miles of solar panel-filled land (about the size of Lake Michigan) would be required to power the entire country, including all 141 million households and businesses, based on 13-14% efficiency for solar modules.
How many square miles of solar would it take to power the world? Dividing the global yearly demand by 400 kW•h per square meter (198,721,800,000,000 / 400) and we arrive at 496,804,500,000 square meters or 496,805 square kilometers (191,817 square miles) as the area required to power the world with solar panels.
