@silas any solar panel you can buy, in the past and now, is an inefficient piece of unrecyclable (realistically) junk,and its production generates so much CO2 that you'll be lucky to get to "net zaro" within it's service life. On top of that, from a migrating bird's perspective it's a body of water where you stop on the way, and since you don't find any water there, you're likely dropping dead before you get wherever you're planning to get to, because you're not an airliner with reserve of fuel.
