Miners are the ones that introduce bitcoin into the circulation. When bitcoin was created, any miner that mine a block is rewarded with 50 BTC, but bitcoin halves every 210000 blocks, the reward reduced into halve. Presently the reward is 6.25 BTC which would reduces to 3.125 after block 840000 has been mined. Each halving takes approximately 4 years.
Solo mining means to setup mining equipments and mine bitcoin yourself, instead of joining a mining pool.
What miners do today is that they just join a mining pool instead because the more the hash rate generated from their mining machine, the more possibility that they will be the ones that would mine the next block. So miners join their miners together to mine and distribute their reward (the bitcoin mined) according to the hashrate the miners contribute.
In every block mined, some transactions are included into the block mined by miners, and the transaction fee of the transaction included by miners are taking as the second reward. Any transaction included into a block were unconfirmed transactions and confirmed after the transactions are included into the block mined by the miner and be confirmed in the process.

You may just prefer to even hold bitcoin instead of mining and joining a mining pool after you check what you will spend and the amount the miner would generate you after electricity bill and other expenses are calculated. But it depends on your country and area if having enough electric and if the electricity is cheaper.
