We know almost NOTHING about exo solar planets, let alone what moons might orbit them. Furthermore the moons orbit isn't perfectly round and as a consequence the relative distance of the sun to the earth and the moon to the earth during each event is far from a constant. And it's nothing more than our approx. location relative to the sun.
And also you are wrong about eclipses in THIS solar system.

The gas giants — Jupiter, Saturn, Uranus and Neptune — can all have total solar eclipses, as they have large moons and the sun appears small to them, Cuk said. But because these planets are made of gas, it would be impossible to stand on them and see such solar eclipses, he said.
However, if you had a special spaceship that could hover near the swirling gas giants, you could very well glimpse a solar eclipse. Jupiter has up to 67 moons, including Ganymede, the largest moon in the solar system. Because Jupiter's moons orbit on the same plane as the sun, the planet can have solar eclipses, Cuk and Van Laerhoven said.
In fact, if you could land on one of Jupiter's moons, you could see its other moons eclipse the sun, the astronomers said.
But what about dwarf planets, such as Pluto? "Charon [Pluto's largest moon] is large enough and close enough to Pluto to produce total solar eclipses for Pluto," Van Laerhoven said. But because the same side of Pluto and Charon always face each other, "only one side of both Pluto and Charon will ever experience eclipses," Cuk wrote.
