Due to an oversized solar array, I have about 10 kW of unused energy per hour during daylight hours. How much can you make per kWh in Bitcoin assuming your electrical cost is zero?
If part of that answer is "it depends on your mining hardware" then could someone supply a table showing the current market cost for each kind of miner and the expected power draw in kW of each model? Which mining hardware would give the most mining power per dollar spent?
This mining profitability calculator seems to give the main variables.

This article seems to suggest that in Jan 2018 the break-even price was $3900 per bitcoin, which corresponded to an electrical cost of 3 cents per kWh.

If yes, mining bitcoin with the available free electricity seems like a poor investment.
