At Pluto’s closest approach to the sun, it gets only 4% of 1% the sunlight that Earth does. That may provide enough light to see dimly by, but not enough to heat it at all.

If you go to NASA's Pluto Time website, you can find out what is the time at which the sunlight you receive equals the brightest sunlight Pluto gets.
