Solar panel experts say President Trump's idea to cover his proposed U.S.-Mexico border wall in solar panels doesn't make much sense — practically or economically. While Trump has raised the possibility as an easy way to make it so the wall "creates energy and pays for itself," experts explained to BuzzFeed News that it's a whole lot more complicated than "just slapping a bunch of solar panels onto the wall."
For starters, Trump's proposed wall is massive. GTM Research's MJ Shiao explained that the sheer enormity of the project means the "harder and more expensive it is to make work." The wall would cross through "multiple states and jurisdictions," likely pitting it against an array of permit requirements, and it would also "likely need a lot of infrastructure, such as transmission lines, to connect the wall's solar power to market," BuzzFeed reported.
