I know guys who are manufacturing solar panels in Europe for export worldwide. If you need cheap ones I can ask them what price they can offer.
I bet since they are manufactured in Europe they are of really high quality. I have seen it take quite a lot of the older Solar panels bolted to a roof facing South, just to heat a swimming pool during the Winter time mid December until mid March in Southern Nevada just outside of Vegas an area known to have historically warmer Winters.
I wonder if a combination of say high end European Manufactured Solar Panels along with one of those Wind Turbines with the 3 ft Titanium Props mounted 30ft in the air on a well secured ground pole. The combination of the wind and solar power produced could be stored in golf cart Batteries that feed into Inverters to convert the energy that then feeds the Bitcoin ASIC Miners. Keep a clean running Natural Gas Generator hooked into the grid to serve as backup on Cloudy/Rainy/Zero Wind days.
Even if a situation were to be properly fine tuned to work, its my guess that equipment costs which could include construction of specialized fire proof sheds to house all the 12-24 Volt Golf Cart Batteries, Inverters, Proper Cabling, concrete pad poured for the Pole with the mounted Wind Turbine, Solar Panels, Wiring, a couple Antminers and an electrician to over see installation. My guess is you would obtain 50% ROI over 20 years. Granted I am just guessing here, I have no idea if any of this would work in the first place along with no reasonable formulas to come to any conclusion. One gentleman above said it more simply and accurate regarding the massive cost of storing the produced power.
If you are able to power an ASIC Bitcoin Miner like a new Antminer R4 through the use of any clean or renewable energy for a profit or not, please make sure to come back to this thread and keep us updated regarding your progress on such a cool project as this.
Good Luck!!!!
Best,
