To me, solar panels are very simplified stuffs compared to say cars, machinery etc. At its core, solar panels are Billions-and-Billions of repetitive patterns of very few basic ingredients. So, whoever is good at scaling the manufacturing will win. Even if the scaled-out panel has efficiency few % lower than state of art.
