How much solar do you need to run two S9's? Can you recommend a good Grid Tie inverter?
Okay with grid tie and 4 cent sell back. You need 8x to do it for free
So 3kwatt x 8 = 24kwatt system
Say you have 6 hours sun on average this counts sunrise angle sunset angle and rain.
You are selling 21kwatt for 6 hours or 126kwatt at 4 cents = 5.04
You are buying 3 kwatt for 18 hours or 54kwatts at 10 cents = 5.40
So you would spend 36 cents a day or 10bucks a month to power the gear.
The 2 s9 would cost 360 in power over the next 3 years
You could earn 2160-360=1800
Of course this does not count the solar field cost.
Which is complex as states have different rules
