You will find that most PuGs have little respect for how much mana you have. This is less true at 51+ but on lower levels your heals are nowhere near as good. Complete heal doesn't really kick in till at least mid 40's. You will be often struggling for every possible med tick to keep your group alive. This could get very stressful, as the fault is not really yours but you will be the one to blame.
Soloing on the other hand is far less stressful, you can also AFK a lot and do many other things. Group tactics are very easy to learn, just read this forum and apply what you learn in game. Things like macros, percentage healing regarding to your mana, etc. You can very easily learn all this low 50's in your typical KC/sol b/CoM group. In this sense grouping till at least 44 doesn't give you much practice. 51+ you will get new fast heal, more cool hp buffs, a rez and all things that make cleric shine. Till that you are just slightly better than druid or shammy.
Oh as folks here say don't forget to respec from Evocation to Alteration somewhere at 49-51. I forgot and was struggling with mana at first while my spec. Alteration slowly went up.
