Re: "clean" solar energy is genuine greenwash.
Easy to find some number for that: 46 vs 164g/kWh
Total life cycle GHG emissions from solar PV systems are similar to other renewables and nuclear energy, and much lower than coal.

It is true to point out however than renewables are front loaded: most of the emissions happen today, not over the lifetime.
It is reasonable to expect solar to improve by a factor of 2 over time, while coal won't.
(My mate just added new panels and they are ~30% lighter/W than those installed 6 years ago)
