When you solo mine there is no definite reward, at least for a while. Solo Mining differs from Pool Mining in that you are trying to generate a block on your own, so instead of being paid for each share you generate (As in Pool Mining - Generally the reward of a block is split up between many miners based on the amount of shares they have submitted), you are only paid when you generate a valid block, and the difficulty has risen a lot since yesterday on the bytecoin network, so this would be quite a feat without a lot of hashing power (e.g. a few GH/s).

TL;DR You would probably be better off pool mining (If you don't have vast amounts of hashing power)
