Solar panels will drop in effectiveness as they get dusty and dirty. They need to be cleaned periodically.

  Of course, and the cleaning interval depends on conditions, sometimes years. Similarly, windows and buildings are also periodically cleaned. I'm not seeing a problem here that supports GP's implication that the new 98% reflective paint is somehow rendered useless vs existing extra-bright ~85% white paint, which already demonstrably works. It seems that the new paint would work better on any cleaning schedule, up to the point where the pollutants fully covered both surfaces. Am I missing something?
