1.4 Solar Panels made of Vibranium, Stalinium, whatever, Lol. I remember them.
I remember when I first disvovered Solar Panels were not invencible in 1.5... I launched a shuttle whose ET was supposed to land on Solar Panels... And of course it exploded... So, I stood there looking at all those flames and said: "Solar Panles aren't invencible anymore??? COOOOOOOOLLL!!!"
