Since solar farms on average make the land they're on darker, therefore making them hotter, I've wondered if megascale PV installations would eventually include a few acres of PDRC panels (engineered materials that reflect visible light but radiate infrared light https://en.wikipedia.org/wiki/Passive_daytime_radiative_cooling https://en.wikipedia.org/wiki/Passive_daytime_radiative_cool... ) to balance out their albedo contribution on net.
They would look pretty funny from altitude. With alternating black solar panels and white radiator panels would they average out to gray? Tweak the pigment mix slightly so they end up a tan-ish resembling the dirt they cover?
