As you said several times, batteries duplicate energy prices rn.
Imo, it's cheaper to 'overbuild' in kwp to guarantee that even not the best productive days you produces enough energy.
Solar panels are really cheap right now.
By the way, what I've said several times is that home mining is a perfect match to consume your unused solar energy.
If you don't have wasted energy, good for you, home mining it's obviously not for you.
