Hi Nicole,
Because Saturn (and its moon Titan) is about 10 times farther from the Sun than Earth, it will get about 1/100 the amount of sunlight. But, at the surface of Titan the sky is really smoggy/hazy so that cuts the sunlight down even further. In the end the intensity of the sunlight on Titan's surfact is only about 1/1000 of that at Earth.
Best,
Christina
