A solar powered website that goes offline when there's no power (solar.lowtechmagazine.com)

This website made me reconsider if 99.9999% SLA and always online is really that important for lots of websites. I used to self-host my own server in my own apartment, but gave up on that after my internet provider had their first major outage that lasted almost a week. Also I didn't want to worry about the fire hazard, or the server going down when I was traveling etc.

But a solar powered server seems interesting, if the batteries could be made fire safe.

This was cool 5 years ago, now you can get solar panels and a home battery big enough to power this thing 24x7 without an issue, even if the sun was fully blacked out for a week

edit: a 40kwh battery would last with the power draw:

Power usage 2.62W

like over a year

A 40Kwh battery is like 10 grand, I'm not sure why you brought that up. I'd be more likely to invest in a second battery and solar panel. It's been up for over 23 weeks right now, I'd guess a second solar panel and battery could keeping it up nearly 100% of the time, and it'd cost under $100 for a 200wh battery and 30w panel.

Now they can get better hardware, but should they? They take seriously the low tech part, and part of being low tech is fighting against consumerism culture and keeping with what they have, which is wotking fine

the chemical battery is often the most expensive and least eco part of the scheme.

There's a lot of articles about supply based usage vs demand based energy production on that website. The idea that it turns off every now and then is sort of part of the authors' intention of showing "we can live with some outages".

This article in particular is a good one: https://solar.lowtechmagazine.com/2017/09/how-not-to-run-a-modern-society-on-solar-and-wind-power-alone/
