I don't really understand why you bought solar panels... usually, the payback period on the actual ASICs is much faster than on solar arrays. What's the grid power cost in your area?
Personally, I think GPU mining will be alive until the end of the year. ETH PoS has been delayed to Q3 at the earliest. GPU returns are much higher than ASICs.
I was thinking of getting into ASIC mining, too, until I realized I would have to rent a small warehouse. Even then, the 100-150 kW of power capacity would only be enough to run 30-40 T19's. It would take 4-6 months to have the utility upgrade the power supply to 500 kW, and that could cost tens of thousands of dollars.
So now I'm considering trying to start it as a GPU warehouse, then converting to ASIC right before PoS. I have much more experience in GPU mining after all.
I don't have a choice, in my country Grid power is not reliable, im talking about 4 hours of Grid power per day, this is discouraging for crypto miners like myself, the only option is building a solar panel which cost me some money, 3.5KV inverter and 12 pieces of 250watt panel with 4 pieces of. 220AH batteries. This is my power source for my ETH farm but now I've get 400watt panels to expand my farm for asic.
