This question already has an answer here:

I just had a solar eclipse followed by a blood moon, but it’s been almost 46 nights since I beat the first mech boss, and the eclipse happened right after beating Plantera a second time.

Is there some kind of probability that defeating certain bosses triggers a solar eclipse?

Solar Eclipses have a 5% chance of occurring each day (starting after defeating one of the mechanical bosses), but they can also be forced by assembling a Solar Tablet.

Since you've beaten Plantera, you should have access to the Jungle Temple, which has both chests (which can hold a Tablet), and mobs farmable for Solar Tablet fragments (you'll need 8).
