I've been a long time reader, but not poster. For the last two years I've been working on a 2000 watt to 4000 watt solar system for my Model Y -- Today I can charge anywhere in the world!

I've also decided to put all the 3D printed parts required to build this online at dartsolar.com -- if you want me to build you one, or if you want to get the free 3D parts...
