Yes.

The side effects of solar panels is indeed a cooler ground underneath. Plants have difficulty growing in the shade.

Panels have a darker shade than most ground they are covering, so they might actually absorb more heat than the typical ground they are covering. They are distorting the local albedo.

I think for geocooling by solar panels shade, the effect is completely local and only surface deep. After all stone/ground is an insulator, and geothermal energy is considered renewable.

If anything on average solar panels will warm the earth, because they are on average darker than whatever they're covering. (this effect is much less than due to CO2)
