Solar system setup costs tens of thousands of dollars on a low scale...hundreds of thousands on a high scale. There is no way a newbie miner will ever want to get into the can of worms. As for recommendations on miners and mining in general, I say wait until the halving because there will be a lot of cheap gear people will be selling and also you can get a better calculation of ROI after the dust settles. This will give you a good amount of time to learn things about mining!

So many newbie miners lately. Do they even realize the upcoming diff jumps due to Bitmain S9 miners? Do they even realize the upcoming block reward halving in July? Do they even realize you need cooling? Do they even realize the btc price won't always go up? They see mining as printing money. If it was that easy, all miners will be rolling in dough. Many miners have lost money, many mining farms went belly-up or burnt down. People have lost their shirts. There's no such thing as free lunch. When will they ever learn?

This game of mining is very difficult.  The road to,riches is not that easy.
