Plus Jupiter has a pretty intense magnetosphere that Titan transits. Jovian space has a lot of self generated radiation that makes it less than hospitable.
Jupiter is 5.2 times farther from the Sun than the Earth. Thanks to the inverse square law, it gets 3.7% of the sunlight that Earth does. You won't be growing any plants there, and solar electric is going to be terrible.
Saturn, which Titan orbits, is 9.6 times farther, and receives 1% of the sunlight that Earth receives.
Mars is much better at 1.5 times farther, and receiving 44% of the sunlight that Earth does.
Also, Titan averages -179C compared to Mars' range from -125C up to 20C.
