Is that worth the electricity cost?
Sure. I make mini solar panel
for my rig
Do you mine only in the day or use battery? What do you think the total cost of mining?
Only on daylight. I thinking about put some
batteries to accumulate energy for night mining,
but its not worth to invest.
I never calculate mining cost but this rig work a lot of time
and I think I return my investment to make it (rig + solar panel).
so mining cost now is 0$
