Thank you, I'll have to check it out.

Just throwing out some napkin math numbers on small scale DIY solar setup:

$0.10/kWh from utility company ~ 3kW ASIC (pick your model) 3kW of panels (~$0.50/W new / ~$0.25/W used) $750-1500 5 max sun hours per day ($1.50/day of power produced / saved from utility (15kWh)) 5kWh of battery cells ~$1500 5kW inverter ~$750 Cables/Fuses/Connectors/Switches ~$250

Total solar equipment $3250 - 4000 Time to ROI on just power production: 6 - 7.5 years. ($4000 / ($1.50/day) / 365 = 7.3 years) Knock off 30% for the US federal solar tax credit that becomes 4.5-5 years. Panels maintain 90% efficiency out to 25 years. Batteries last ~10 years.

~$400 S17 @ 73Th/s currently makes ~15000 sats/day but we only have 5 hours of equivalent max power so 15000 * 5/24 = 3125 sats/day or ~$1

The extra ~$1/day cuts down your ROI from 5 years to just over 3 years to pay off your combined solar + mining setup. Certainly able to optimize this more with better price and power efficiency.

As always with mining returns calculations, there are unknowns like BTC/USD price and difficulty adjustments. Having your own infrastructure is inherently valuable since your cost doesn't inflate AND you have more sovereignty because you don't rely on others to produce electricity.

I think these returns, as long as I am not missing something important, are good enough that's it's worth trying IMO.
