  • OK I didn’t see that, that’s bigger than I expected, we make about 12.5 MWh per year on our 11.2 kWh panels = 1.1 MWh per kWh capacity.
    Your system is 5.1 kWh but you only make 3.8 MWh per year = 0.75 MWh per kWh capacity.
    Meaning we have 50% higher yield per kWh rated capacity!

    So our production remains 3.3 times higher than yours, despite we only have twice the capacity.
    But our panels are pretty optimally placed towards the south.

    Considering you are further south compared to us, I’m surprised your yield is so low, despite London is infamous for being cloudy.


  • It is not remotely close to economically viable to go off grid, and the exports of solar power to the grid pay for the connection anyway.
    The reason to have a battery is that it lasts through the night, or even with a smaller system, it can handle dinner time, which is the most expensive time of day to buy electricity.
    Now if you live in some remote area without a grid, a generator is a way better option than a huge battery.
    Maybe if you live somewhere very sunny, like Spain and especially southern parts of USA you can probably do it with a modest battery that can handle a couple of days.
    In the summer we can make enough electricity on by far the most cloudy days, but in the winter, the sun can’t penetrate the clouds nearly as well.
    Admittedly London is south of where I live, which is close to the most southern part of Denmark, but on the other hand London is infamous for grey weather with heavy clouds.



  • Seems to me his panel capacity is to small anyway.
    We have 11 kWh panels, and yes in the summer we routinely produce 4 times more than we use, and we have a 7.5 kWh battery But November December and January it’s not even close to enough.

    In the Winter you can easily have a week with near zero production:
    Our Import / export from grid last year:
    November 215 / 59 kWh
    December 300 15 kWh
    January 268 / 34 kWh

    Despite we have almost 3 times the capacity, and produce more than twice what we use per year, and we have a decent battery and believe it or not, even the shortest day we can produce enough power for a whole 24 hour day if it’s a clear day! But we can also have clouds for 14 days!
    But for those months we imported 783 kWh and exported 108 that could have been used with bigger battery. But the net import was still 675 kWh!! For those 3 months, and that’s the minimum size battery we could have managed with, and then we even need 10% extra to compensate for charge/discharge losses.

    TLDR:
    Minimum 740 kWh battery in our case, and that’s without heating, because we use wood pellets.

    That means it would require at least the equivalent of 10 high end fully electric car batteries. But also a very hefty inverter, which AFAIK ads about 50% the price of the battery.

    PS: Already in February we exported more than we imported.


  • “owner” is typically the maintainer,

    Nope, AFAIK that is not legally applicable, that is very clear with licenses like MIT BSD etc, and for GPL in all versions it’s very explicitly stated in the license.
    You can also release as simply public domain, which very obviously means nobody owns as it is owned by everybody.
    Generally if you give something away for free, you can’t be claimed to be the owner.
    I have no idea where that idea should come from, some typical anti EU alarmists maybe? And I bet there is zero legal precedent for that. And I seriously doubt any lawyer would support your claim.

    If however you choose a license where the creator keeps ownership it may be different, but then it’s not FOSS.


  • I have no idea what I’m supposed to see from you link? I don’t see any particular legal knowledge, or description of any particular legal consequences, and I have no idea what the point is???
    Obviously software provided for free “as is”, cannot be required to be maintained. And if it is owned by the public which is the case with FOSS, there is no “owner” who can be made responsible.

    If however the software is part of a commercial package, the one supplying the package has responsibility for the package supplied, you can’t just supply open source software as part of a commercial product, and waive all responsibility for your product in that regard.



  • I think it does in some cases, like if you buy a System 76 computer with PopOS, or you buy a server with Red Hat.
    However if you install a Linux OS yourself, that is available free of charge, there isn’t any money to claim back, and it would be illogical if there should be demands on updates.

    I think logically there needs to be money involved, so if you download PopOS you’re on your own, but if you bought a computer with PopOS installed it is part of a package.

    I’m not a lawyer, but from my experience this is how things typically work.

    Edit PS:
    If it’s FOSS or FLOSS there also technically isn’t any owner, so there is no legal person to make a claim against.



  • "Microsoft’s decision to end support for Windows 10 could make 400 million computers obsolete

    This is more stupid, and I absolutely agree with the article it shouldn’t be legal to end support of an OS this quickly, mind you this is not update to a new OS, like is common on phones, but mostly security updates for the OS you purchased with the device.
    I absolutely think 10 years should be a minimum, but for PC, I can easily see an argument for 15 years, as many systems are purpose built, and should keep working even if an OS is discontinued.

    A similar argument can be made for phones, but maybe that should just be 10 or maybe even just 5 years, which very few phones have. My vote is on 10 years, because what some companies have been doing for a long time, only supporting security updates for 3 years is not acceptable IMO. If the phone is free to install custom ROM unhindered, I would be more understanding, but phones are generally locked, potentially rendering them worthless if updates are not available.

    I would expect that to be a gradual effect, for me it absolutely wasn’t gradual. It was straight from getting the flu almost every time it was around, to never getting it for 15 years straight!

    This is not “less often” it’s straight from always to never.






  • The logic is along the lines:
    I’m starving and they want to give everybody food. But I don’t want everybody to have food, I want more food just for ME!.

    And:
    They want freedom of religion (normalo people) , but as a right wing extremist I don’t want that, I want all religious privileges for MY religion, and none for the others. So I can discriminate them, but they can’t discriminate me.

    There is no living peacefully with such people, they hate everything that is in any way different from themselves, and they are selfish to a degree they believe they are somehow entitled to have it better than other people.

    And the “somehow” is because of their race and their religion which is barely religion, because they have zero actual religious knowledge, it’s merely a faith they believe agree with all their own prejudices about the world,and their sense of entitlement.

    It’s insane that so many humans have such low intelligence. And I’m not talking about learning from books and being good at science, the bigger problem is that any sensible social intelligence is completely gone for very large parts of American society, and we just saw it’s a problem in UK too.


  • Absolutely, when white men are being oppressed, it’s generally by other white men. So I guess white men are fighting back against other white people. But no that’s not it, for some reason they are oppressing minorities of all kinds instead, because skin color and culture scares them. In fact everything scares them, like science and everything based on reason even human rights are scaring them now, so they want to take them away.
    Why? Because they are so fucking stupid, they are scared of everything about society, because they understand nothing, and that makes them scared.
    You don’t have to be white for that, problem is when the majority with all the money and power feel that way, things must have gone completely haywire in that society. They are oppressed by their own, but blame everybody else!!!

    Regarding Charlie Kirk specifically, he was white right wing extremist who condoned gun violence, who was killed by another white right wing extremist, who used gun violence to kill him.

    What the fuck is it they think they are protesting? They are their own worst enemy, not normal sensible people who actually care about other people. Or what they call “radical left”.
