The surprising inference from me, as an energy layman, is that solar output coincides with periods of peak demand. Obviously this is seasonally adjusted, but in an era when the Saudis have solar contracts being supplied for $10USD/MWh [0], the potential profits for a solar provider at periods of peak demand seem more than sufficient to encourage investment, especially with interest rates still at a historic low for big capital projects.
So, what gives? Where's the solar?
