I have solar panels that I planned on using for power, I have an empty and unused clothing closet with 3 shelves in it, off in a corner of my house, I have no past mining experience, if there is somewhere easier to start I will gladly try that if this is too hard for me. I live in the US and i am not sure where this item would ship from, and is a PSU a power supply? And if that is what it is can I purchase that? If it is something else please let me know.
If an S9 is a better deal than I might go with that, I just saw the S7 on an article and it said that it was decent.
What other methods are there that I can try to use
I am here to learn whatever I can, if there is an article or two that you think I should read just send a link or name it and I'll look it up and read it so that I can have some knowledge about this.
Be carefull there... It looks like you have half a plan, don't do this without having a full plan and after examining everything that could potentially go wrong.
I've never understood people that are really into solar mining. I have solar panels at home to, but after a deduct the initial price, and the extra taxation my governement issues on solar panel owners, the power is cheaper, but certainly not free... Maybe that differs from country to country, but you will have to agree solar panels are rather expensive, and you'll need to use power from the grid to mine at night, or you'll need to invest in battries.
You can use
http://www.coinwarz.com/calculators/bitcoin-mining-calculator to calculate if you can make a profit with your power and any ASIC you buy, but keep in mind it calculates the current profit. When prices drop, diff increases or blocks halve, your profit goes down.
To answer the rest of your questions:
- a PSU is a power supply, plenty of topics on this forum that discuss this
- shipping costs and import duty depends on where you live and where the sender lives. bitmain is chinese, both transport and import will be expensive. But maybe you can buy one second hand, or from a local reseller?
- an S9 has a much better power/hash ratio (it can deliver far more hashes per Kwu), but it's harder to get them second hand
- shelves in a closed clauset might not be an ideal place to store S7/S9's... What about the heat, what about the noise, how will you get power there?
