“large scale solar economics have already reached grid parity:”
Except at night.
Or in the low sun wintertime.
Or areas where it rains and/or is cloudy much of the time.
Or areas where it frequently hails large hailstones.
Or where the population is so built up, there’s no place to site giant solar farms.
Other than that, yeah, solar is great!
If we could only cover wind turbines with solar panels then we could kill two birds ... and a few desert tortoises ... with a single energy system!
You forgot one:
Except where large scale solar projects have already been built and are underperforming pie in the sky predictions of their output.
