Maybe I’m connected to the wrong relays or maybe what I post isn’t interesting, but it feels like I’m posting int a black hole. 😅

if you don't have batteries, you are covering only small part of 24h of your consumption. still reliant on grid.

also, panels take a lot of space, so overproduction takes space, costs money and ROI is smaller.

panels are cheap, but you need often permission to build more and of course inverter (you can't connect infinite amount of panels to an inverter) and then you don't even mine enough to buy energy for night for that money. if you had batteries, it would be better. 😀

Regarding solar panels price right now:

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.

Interesting perspective! What qualities do you think are necessary for us to trust AI in the future? #AItrustworthiness

it duplicates the price, but still cheaper than the grid. and you have backup when the grid goes down.

giving excess to the grid using virtual battery (tax free) and then consuming it later is still better deal than mining. for the saved amount, buy BTC.

do you actually do this BTW?

that means you overpaid on solar, if you have 10kWh day excess (even sometimes), you paid good 15k for energy you don't need and can't store.

so the cost is not zero, you overbuilt the solar farm.

if you have the system set correctly, you don't have much excess you can't store, certainly not 10kWh per day, even if there are some exceptional days.

also, in many countries, there's a limit of 10kWp, if you go more than that, you enter into commercial producer area - regulations, taxes, ...

You are thinking on it in the wrong way:

- It's not installing solar to do home mining.

- It's using home mining to consume your wasted or unused solar energy.

It's not about building a mining operation in your house. It's about making more profitable your solar installation while helping the decentralization pleb-mining.

So, for your opex calculation your energy costs are zero, as you are going to consume unused energy.

The good old S9 has a breakeven of $0.04/kWh right now, operating in efficient power range ofc.

A pair of them can chew up something between 10-15 kWh per day, that could be $0.4 or $0.5 a day.

You are not going to be financially independent with that, of course!! 😊

But in a few months your (small) miner capex are paid, and your mining rewards would be 100% profits, although small! 😁

You can scale this up with newer miners adapting to your wasted energy case, or reuse the produced heat to help warming up your house.

Btw, buying Bitcoin is not exclusive to home mining with wasted solar energy, of course!

What about mining for fun in the summer with an old asic (that doesn't cost much)? Of course it won't mine much. I wonder if it's better than selling the electricity to grid at low (negative?) prices.

But yeah, no AC has to be involved. 🤔

I have a solar system and was doing this calculation several times, also tried other people who build solar systems and understand Bitcoin mining.

if you find a way to do it without being in brutal loss, let me know. but show numbers.

with current solar systems, assuming you use everything it produces over lifetime, the cost per kWh is 6-8 cents. if you want to use batteries, the price doubles.

assuming a 3kW miner and 6 hours of peak sunshine (that's way overblown though), you need at least 12kWp of panels. that will not fit on most roofs anyway, but if you have a greenhouse or a parking lot, you can use that, along with let's say 3x3kWh batteries.

you still have not made anything for the house, just for the miner, which also costs a lot of money and if you want to see that money back, you can't not run it, the difficulty increase will kill ROI.

the professional miners get 3-4 cents per kWh and that's 24/7.

just buy Bitcoin instead of the miner and use the solar system for all your other energy needs.

p.s.: I have not talked about cooling. you need another 3kW AC unit to cool the miner.

Another super-awesome* thing about the #xz situation is all these people using LLMs to write lots of new, pretty average code, that's opaque to humans, really fast.

We don't need more code, we need less.

Working on something new ...

home mining from household renewables unfortunately does not work. you increase monetary sovereignty by buying Bitcoin.

if you have the miner, you have to run and cool it 24/7 and then maybe it works. solar energy is at least 3x than what profitable miners get from hydroelectric dams. and that's before you solved the problem of the night.

My heart goes out to xz. A single maintainer, who was clearly in a rough place with mental health, screaming out to the world for some help and additional contributions, and somebody shows up wanting to help. Could you imagine how happy that maintainer was? They were no longer alone.

And it turns out the only reason somebody wanted to help them was nefarious. I can’t imagine how they feel right now as everyone is blaming them. I hope they’re ok.

#Bitcoin isn’t about harkening back to the “glory days” of old, like some Trump campaign slogan to “Make America Great Again.”

It’s about moving forward, envisioning a world built for and by everyone with a permissonless, open monitory system to fit it

Not backward. Not left, not right. Forward.

If the true cause and effect isn't available, humans will work hard to invent one.

yes, we're not going back, but we can get inspired. I would add some kind of energy production capacity (definitely solar panels, maybe a small wind turbine).

at least a starlink and some backup internet connection. maybe sell excess electricity for sats in the parking lot, have a delivery boxes for neighbors.

What about this?
