- PV-Mining Box Thread☀️⛏️ - Part #6:
I saved 16,87€ by PV mining last month with old and inefficient S9 miners. How the fuck is that possible!?
Let’s have a look at my mining rewards of the last month. February 2023. Numbers!

February’s weather was surprisingly nice. After all it’s a winter month, one of the 4 worst months for PV power production in the northern hemisphere.
Averages per month:
⚡️ 3,3TH/s hashrate
⚡️ 273W power consumption.
Averages per day:
⚡️ 6,5 kWh per day, which were used to heat my livingroom
⚡️1011 Sats per day (or 0,00001011 BTC)
Cost:
⚡️195 kWh Power consumption by 2xS9 miners
⚡️ „price“ of 1kWh of my own solar power is 0,067€ (as I could sell it for that price to the grid, if I wouldn't consume it myself) - that’s 13,13€ total.
⚡️0,00030317 BTC earned in total. ~6,60€ (at 22.000€ per BTC)
⚡️That‘s a loss of 13,13€ - 6,60€ = 6,53€ right?
WRONG! Because I also had to buy 195 kWh of natural gas LESS to heat my living room!
⚡️gas price is 0,12€ per kWh atm (german issues…). So I saved 23,40€ in heating cost while mining.
🧮 SO IN TOTAL, mining saved me 23,40€ - 6,53€ = 16,87€ in February 2023.
And that’s so fucking cool… ⚡️💜🧡🔥
And as a side effect I also:
🧡 helped securing the finality of BTC transactions and
🧡 stole some rewards from C02 emitting miners and
🧡 raised the percentage of green mining. It's around 53% atm! Have a look at #[0] 's latest notes…
