Holy Cow.
If I trust whattomine: your power consumption id 370watt+ Motherboard ( to mine ethereum, because RVN ts higher)
Can we call it 500 w ?
24hour*,5 its 12 KWh/ day its 4380 Kwh / year
you have 1.2 Kw Nominal
your system at best .. will produce 1600 Kwh / year facing south in free place can be better only if you are in Denver or Colombia or at very high altitude but not that much
Go here and check by yourself.
https://ec.europa.eu/jrc/en/pvgis#, just pinpoint your location the map where you are and write 1.2 in the KW peak box and hit calculate.
At the end you need to triple your actual solar PV system to have those running 24/7/365.
In theory!
in reality When you hit calculate its show a table and a graph ( kind of gaussian distribution curve).
That will show you that , in the summer you will produce more than enough for running the system, but not for charging the battery fully and running the system.
Then if you multiply your 1.2 Kw by 3, the yearly production will be enough BUT (the winter + part of autumn and spring) production will NOT be enough!
As a reference my system:
When finished I will have 9.9 Kw 380 V installed system facing south with 11.8 ( x3) KWH 3phase BYD battery. This give me an a base of 1.5 Kwh/24/365 that I count for the two rigs.
On top there is an electrichal water heating pump for bath & Kitchen use
Winter heating is done by wood as I am living in a forest with difficult access.
The two rigs (1 AMD 1 NVDA) are located one in the basement (AMD, a little noisy, 6 x RX 470 ) one in the first floor Nvda (6 x 3060TI/3070 Zotac) is very quiet
There is an AVS automatic ventilation system that is spreading the heat where is needed between the floors.
The excess energy produced during the summer is "gifted" to the government in exchange for the 65 % tax deduction....
When there is (too much) snow, I can purchase electricity from the grid at 0.27 €(33$cents) but that make mining not convenient.
in short ? I will sell a 1/2 of GPU and purchase some solar panels... price is around 30€ cents / watt those days so probably you can purchase 1 Kwp with one 1660Ti
