Comment Wavelength matters too? (Score 1) 327
My first though without even reading the summary:
Of course pointing it to the South would "catch" more integrated spectrum, but not all of that can be converted to electricity efficiently (they are more efficient for longer wavelength), so it should not *hurt* much to till them westwards (or eastwards), where/when blue light ("useless for") is filtered by the atmosphere...
By the way, blue light is still absorbed/heats/damages the cells, but not gets converted to voltage. Or some such...
Aligning with peak demand might make more sense though.
