The only workable solution is Solar panels as sunlight duration during all weathers is more than 10 Hrs/day which is quite sufficient . Solar system need one time huge investment but it will continue supplying electricity at zero dollar cost for many decades.
10 hours of peak sun hours is just impossible regardless of where you live, but then if even if we were to go with the assumption that you do get 10 hours, what happens in the remaining 14 hours? if your miner sits idle it will never ROI, so you still need to pull from the grid, mining solar is pretty much useless unless you it has tax benefits of some kind like how things are with our friend phill, but just go and buy a few panels to mine bitcoin won't work.
