Currently I mine about 6000-8000 sats a day depending on the weather and fees.

A super rough break down:

Solar panels $30 x 60 - $1800
Batteries $200 x 8 - $1600
Inverters $600 x 2 - $1200
Wiring, smart outlets, relays, connwctors, breakers, misc - $500

So a guess would be about $5000 for this setup not including the miners

I bought the miners for a lot back in the day, .25btc each(don't remember the USD cost). Now you can get these for a fraction of that.
