Abnormal temperatures and lack of humidity caused by the heat island effect of blacktop for miles and miles in every direction.

Adoption of greenspace and far more solar panels in Phoenix could significantly cut down on this phenomena.

Have you seen metro Phoenix from higher elevation? It's far more green than the surrounding desert already. Further, PV installations worsen the heat island effect and Phoenix is one of the leading cities in the US for installation numbers.

Shading the ground beneath the solar panels should have a localized cooling effect, since the panels don't have as much thermal mass.

The other comments pretty well address both of those points.

I'd be glad to see more information as regards the conditions which lead to that conclusion

Well, they do have lots of green grass yards needing tons of irrigation....

Completely agree, xeriscaping is far more beneficial. There are lots of natural desert grasses, lawn isn't one of them

What do solar panels have to do with it? What color are solar panels? Do they produce less heat island effect than "blacktop"?

They don’t reflect a lot of light which ordinarily means a material is absorbing all the energy and turning it to heat, but in the case of solar panels you’re turning maybe 20% of it into electricity instead

Solar panels have an albedo of ~0.3. Asphalt around ~0.05. That makes it 6x better in terms of heat reflected.

They can be used to power a fridge
