At this point i think removing any heat from ground is a net win.
Solar is just transforming light into electricity, i don’t think it’s removing any heat from the system unfortunately, unlike radiative cooling paint.
Now that we should be painting any tropical building we can with.
I would expect large solar farms increase heat, as the panels are dark and absorb a lot of energy (by design). Normal groundcover is not so dark and reflects a higher percentage of sunlight.
Considering how little of the landmass needs to be covered, any effects are absolutely trivial compared to CO2 gains.
