Born in the town, the former Macclesfield Town defender and midfielder is Tim Flowers’ first summer signing.
He was a National League champion with the Silkmen a year ago - and he hoped more glory could be on its way.
Moors finished as runners up last season but were defeated by AFC Fylde in the play-offs.
Hancox signs a two year deal with his hometown team and after taking Macc up he sees no reason why Solihull can’t go the same way.
As soon as I heard of the interest, it was brilliant,” he told the club’s official website.
“I’m a local lad, from the area and when it came about, I was like ‘yeah this is perfect’. I couldn’t turn it down.
“The whole ambition of the club is really attractive and everything’s going in the right way. I’m just glad that I’m a part of that now.
“Being a local boy in Solihull, being born here I’d like to think that here in Solihull we can do things our own way and go one step further than last season.”
