[Superman] Yellow sunlight exposure and Kryptonians

Does the level of exposure to yellow sunlight impact a Kryptonian's abilities? Is Superman less powerful on Pluto than on Earth? How long does a Kryptonian need to be exposed to yellow sunlight to develop abilities? How long can they be away from it before losing their abilities?

Kryptonians are solar batteries. As long as they have a charge, their powers remain undiminished.

They can be drained over time by exerting themselves in deep space, but any Kryptonian that has spent more than a couple years exposed to the equivalent yellow sun radiation that the Earth gets isn't going to be any less powerful in deep space than they would be on Earth.

Kryptonians can "sun-dip," enter the outer layers of the sun, in order to gain a temporary boost in strength. For the post-Crisis/pre-Flashpoint Kal-El, fifteen minutes sundipping provided him with a 3x boost to his abilities.

The post-Flashpoint Superman has recently been drained. He discovered a new ability to discharge all of his stored solar energy at once, effectively nuking the location at the cost of all of his powers for about a day or so, then his powers start to come back.
