Are you assuming that you have a planet that is $d$ AU from a star with radius $r$, with a moon with distance $d_m$ away from the planet and radius $r_m$?

@fasterthanlight my initial answer would be yes but something may be going over my head.

looks good, *thanks!* It'll be hard to answer though, requires a model of the statistical distribution of moons about exoplanets. Different but related: [How to find Exomoons?](https://astronomy.stackexchange.com/q/11128/7982) and [What's still needed before we can observe orbits of exomoons thereby weighing exoplanets?](https://astronomy.stackexchange.com/q/39083/7982)

We don't know any exo- moons. Thus there is no data to check

I don't know. BUT... to get a solar eclipse a planet needs a moon with a size/orbital radius that will basically cover the star. Mercury and Venus don't have moons because they're too close to the sun, a moon couldn't exist in a stable orbit. So it can be figured which exoplanets CAN'T have a solar eclipse.
