If it helps with snow, white paint or light coloured concrete should work fine too. No?
As the planet warms, we’ll increasingly need to paint flat roofs white anyway.

Yeah, but the people I was taking to worked in grid scale rather than utility scale, so in fields rather than buildings. You’d want to avoid paving over the whole field for cost, but also avoiding huge runoff. They are often also renting the fields for 20 to 30 years rather than buying them outright, so paving over the whole thing wouldn’t be appreciated.
