Solosis doesn't have a set Hidden Power type for its entire species, which means your Solosis's Hidden Power will definitely differ from a wild Solosis's. Its Hidden Power type is determined by its IVs. However, you can go to the Hidden Power checker to find out your Solosis's Hidden Power type is easily. I don't know what game you're in, so here's where all the Hidden Power checkers are for each game.
Hope I was able to help!
