Probably unlikely to save any money due to the cost of the batts and wouldn't actually be that green, but it would be totally off-grid.
    Grid tie inverter and panels do the trick, no need to bother with batteries if you are connected to the grid anyway.

    There was a time in the past (386 days), where they used NiCd soldered batteries, these also often kept the config data. Unfortunately, they would eventually leak and had to the removed or risk damaging the motherboard, so storing those machines is bad if you don't rip the thing first...

    Inverters are expensive, and require an electrician to install. Getting a 12V machine and running straight off DC is a simpler and cheaper way of doing it if you're just trying to run a single PC off solar power. I know a guy who's converted part of his home office to run off a system like this (he's put in DC lighting), the rest of his place still runs off the grid power.

    I've got a 2kW PV array with a grid tied inverter myself, but they aren't cheap.

    I usually put it to sleep; I restart about once a week or only for maintenance, or for switching to Windows to play minecraft.

    Minecraft runs fine on Ubuntu snoo, it's Java.

    The small (500W) ones cost around 200$ according to amazon, that and a single (or 2~4) 100w panel is a good starting choice imo. Even if you only put 100W or 200W in the opposite direction, thats net savings; and the install is a one time issue; your panel(s) could last a decade easily and the small savings will help your bills; inverter+100w panel would cost around 400$, you could add another panel, for 200$ more, etc. Batteries add unnecessary overhead for those starting to explore this saving method.

    If everyone added small grid tie inverters + panels to their homes; the global net savings would be huge. And now led lighting is becoming reality, i have a couple of 10w led lamps that could blind me if looked directly at (I'm bouncing the light).

    Grid tie is excellent because you don't have to bother with maintaining those heavy, few year lasting batteries. If you produce 100w in the day, and consume 300w in the night, your would be actually consuming 200w (this would be better measured with kW/h but i hope you get it).

    Its also much more friendlier to get people introduced to solar panels, just hire someone to install it once, and enjoy savings for the next decade...

    Why would anyone leave a naked roof if they knew how simple and inexpensive this really is?

    I believe there are some bios with a setting to panic about it, quite silly imo. Take it out and only the clock stops to move, this is not worth bothering the user, even windows syncs to ntp servers nowdays.

    No, CMOS settings got lost after a black out due to battery not functioning. And plug and play is not bullet proof. So it was trying to boot from the wrong hard drive.

    Sure, batteries are definitely the weak link in an off-grid system. We really need better technology for electricity storage, that would help on-grid systems too. We've got storage systems for renewable domestic heat, we need it for electricity too.

    I do wonder how long your $200 inverter would last though, who makes it? I'll be happy with mine if it lasts 10 years, and that's for a decent-brand 2kW one. They're generally the most flaky component of a PV system, and first to go bung.

    I wouldn't necessarily wax lyrical about how cheap PV systems are, because they aren't particularly. Here in the UK the reward you get for the energy you export to the grid is very generous, so they're good value financially, but you do have to stump up a non-trivial amount of cash initially. Payback on my system should be about 8 years, but I'll be laughing for the remaining 17 years I'm owed Feed-In Tariff payments.
