To the OP it's not entirely about the gear. That varies depending on the dive and if you are going to solo dive you should be able to figure out roughly what you need (though questions can be asked for refinement, but just a general question strikes me as someone who doesn't have the experience to solo dive). I occassionally do solo dives under piers that are 5m deep. I don't use redundant air most of the time on dives like that. But when I am doing a 30m solo wreck dive, I will use twins.
Personally, I think that one is ready for solo diving when they have experienced a few major catastrophies underwater and they know how they will react when the s*** hits the fan. Most of the time (but not always) people with 25-49 dives have not experienced this. And they also in general do not avoid problems as much as those with more experience, which is another part of what makes one ready for solo diving.
My advice would be to get more experience, before solo diving. I am aware this advice does not go down well when I give it but solo diving is serious business, and not to be taken lightly.
