The important thing is what the parties attack roll bonuses are. Solos generally have a slightly higher defense for it's level. Add in a few more levels and hitting the monster will be very difficult.
I just sent my group of 5's (6 of them) through an encounter with a 4th lvl solo (xp budget 2150 - just above 8th lvl for them) And they barely noticed there was a fight. Depends on what sort of encounter you have.
