The only way a solar plant could be useful for us is if the albedo of the panels are so small so it compensates for the power drain it is designed to do.

Solar panels are a deep black and do a superb job of absorbing the radiation from
the sun. The ones on my house and my motorhome feel significantly hotter than the
roof area without a solar panel on it.

What might keep them from getting hotter than the ground near a solar farm is the
wind cools BOTH sides of the panel - air circulation across the bottom of the
panel is an important design consideration, as a cooler panel is more efficient.
