The reason they are tilted is to maximize irradiance hitting the panel. At a 0 degree angle (flat on the ground) you get a a lot around noon and then very little.
This approach surely reduces land usage but what is the output per acre?
I’d be really surprised if it’s higher than with tilted modules.
The gov optimization function is to maximize production not employment. This is an ongoing fallacy in the political narrative but the unseen consequences of making up jobs is overall lower purchasing power.
