yEs, I have cheap electricity and also I don't understand how to use this what to mine site?
What wallet you are talking about?
The wallet is only you to store your coins but if you are talking about solo mining I think you can mine solo except for new coins with low difficulty.
You just need the wallet where you can receive your reward and you can mine coins directly from many pools with your GPU miner.
You can use this tool to find pools to coins you want to mine
