Considering cost of mining equipments and the bulk calculation of electricity cost required to run them, there is a high chance it would eventually turn out unprofitable for you especially as a solo miner. The hash rate an average solo miner generates is barely enough to pick up and confirm transactions fast enough, plus getting the block reward as a solo miner is a very thin chance of luck. Joining a pool isn't much different since you percentage reward still depends on how much hashrate you contribute to the pool.
