I've lowered my operating cost from 24 cents home mining down to 8 cents mining at colo now where most of my rigs are at.
I also self installed 20 solar panels on my home to power my house and 1 gpu rig thats in my office with a ceiling exhaust vent fan. So i did make some investments to lower my operating cost. I did borrow from my 401k so I'm practically hedging the stock market and not selling cryptos at the lows to fund my solar.
So that's how I planned for summer 2019.
Looking back I would have made more if I just bought btc at 3300 but my wife was pissed about the markets in December/Jan and threaten to divorce me if i bought more crypto during that time. So we decided on solar to hedge out our long term strategy that works for both of us.
Mining the Sun power is a lot of fun lately.
I did actually laugh when reading up about that divorce thing and for sure you wife now do regret on stopping you that time if she do currently see
on whats the price of bitcoin as of this moment but well in regards on the solar panel thing.This might be a good option but havent you consider
on reaching up your ROI?
Since I did a self installation and got my solar panels from wholesalesolar.com. I will actually less than a 4 year ROI. Thats actually faster ROI than a gpu rig build if your electricity is a little bit on the high side. And the biggest benefit is after the equipment is paid off the solar system will keep giving me savings for 26 years+ whereas a gpu rig after 4 years roi of mining the cards will be garbage.
Here's a breakdown of their cost.
https://www.wholesalesolar.com/shop/grid-tie-packagessolar system with shipping $8500 for 891 kwatts a month. This is the average house hold use or close to an S9 running all the time.
Solar Design $275
City Permit approval $286
Junction box and conduit pipes and extra wires $300
Total cost before rebate $ 9361
Solar Rebate from State of 30 percent. = - $2808
Final cost after rebate $ 6553 (I'm sure some of you 1080 ti folks spent close to this on your single gpu rig build out with 6-8 gpus)
ROI time = Your monthly home energy cost without solar. Say for example around $150. Your roi is now $6553 divide it by $150 which equals 43.68 months or 3.64 years.
Since these figures are very close to what a gpu rig takes to ROI and also the gpu system cost is also close in price of a solar system. One should really consider going solar especially if your electric is above 15 cents.
Do take into account for my specific situation I live in california and electric rate is 22 cents for tier 1 electric use. My roi time is actually much faster due to high price. 891 kwatt generation multiply 0.22 cents = $196 month of electric use per month without solar. $6553 divide by $196 = 2.78 years ROI. But i'll round up since I probably need to pay minumum pge electric delievery charge. 3 years ROI is not bad and I'll enjoy 27 years + of free energy
