It used to be Chinese panels were the worse quality with short lifespans. Now they're everywhere.

They don't have short lifespans anymore.

Do you have a good source for lifespans of panels by country of origin?

I meant it as a general thing. These days all manufacturers, from all countries, offer 20+ year warranties. Not just Chinese ones.

However you inspired me to do some research, and I found this: https://www.cnet.com/home/energy-and-utilities/best-solar-pa....

The article lists top PV manufacturers and their efficiency ratings, production warranty, and other statistics. There are several Chinese companies on the list with 25+ year warranties. The article's top-rated manufacturer in the category of "Longest production warranty" is ZNShine Solar, a Chinese company that offers a 30 year warranty.


Thanks! What is the significance of all-black models?

I think it's more cosmetic than anything else. All black panels blend in better with dark roofs.

80% of panels are made in China, if they were all so terrible I doubt they would dominate the market so much

> if they were all so terrible I doubt they would dominate the market

Plenty of markets are dominated by the less-durable product offered at a lower up-front cost.


They all come with ~30 years warranty, I think you're stuck in the 1970s when it comes to Chines manufacturing capabilities, the top of the line chinese factories are just as good as EU/US ones, probably even more high tech

> you're stuck in the 1970s when it comes to Chines manufacturing capabilities

Probably not, having done contract manufacturing in China quite recently. Asking for a source isn't the same as disputing an assertion.

> top of the line chinese factories are just as good as EU/US ones, probably even more high tech

This is my guess. I like to substantiate my guesses.


iPhones are made in china...

For a residential setting, installation quality probably dominates, and I doubt country of origin is statistically significant. Otherwise look at warranties which specify a performance curve over lifetime (generally 25y, also some are independently guaranteed by an insurance company that might actually survive that long). There are public performance datasets from NREL, TUV, but be careful about choosing representative examples (e.g. utility scale reliability is different from rooftop)

It's just a bunch of drama from two American companies trying to lock in their lead via government regulation. Meanwhile I'll just keep using open-weight models.

Don't you normally have about a kilo (or 500g?) excess as backup energy stored in your muscles and liver(?)? Why would taking a few dozen grams help?

Locked up and waiting for signals to release doesn't do much good.

My wife and I have used electric toothbrushes (sonicare) for years. I used to shop for the best deal and the lifetimes on the brushes was not great - the battery would hold less and less charge to the point you had to charge it daily or sometines the body would crack and the brush just fail completely.

During the pandemic I decided to try a different approach by buying the model with the largest battery. This is of course their most expensive model and has a bunch of features you'll never use (WiFi, rfid, etc). They are still going strong after six years. I would have had to replace a cheaper model at least once in this timeframe - even two.


I had good luck with soldering repairs with them. The wires are super thin at the base of the brush where the wireless charging coil connects to the PCB and they often break.

Yesterday I saw a full-sized 100% electric Volvo semi-truck here in Zurich. It was owned by Aldi and making a delivery to one of their stores. It was a bit louder than I expected but nevertheless impressive.

"Der Volvo-Lastwagen, der für ein Gesamtgewicht von 42 Tonnen zugelassen ist und eine Reichweite von bis zu 320 Kilometern hat"

320km doesn't seem like a long distance for a truck, curious how that works in practice


It really depends on the context and the country. In practice, most people in my country live within 100 km of a commercial harbor (river or sea), so 320km for most foreign imports it seems enough. Grocery store chains have to be within 2 hours from the packing center, so for food too, 320km seems enough. Barely, but enough).

It's optimised for distance to and from the depot and in-city store locations. Presumably it charges at the depot while loading.

Trucks have a lot more space for batteries, so with EV trucks it's all about balancing range and weight for the task. More range means less useful load.


Some Australian electric prime movers (truck that pulls the load on trailers) are using a fork lift in / fork lift out swappable giant battery pack - 10 minute change over from truck to charging station, freshly charged unit back to truck.


320km must be either optimised for their trip or an older model.

Watch some of these https://www.youtube.com/channel/UCXNB7Q_d1qC0mFjn6bt8YvQ


320km seems like a very long distance to go without a rest stop.

Why is all this drama coming only from the American companies?

It's mostly coming from two out of many American companies that happen to have the highest concentration of people from a very specific movement born in California long before the current AI wave. In fact Anthropic's entire internal culture was built around their views. The fact they operate massive amounts of money doesn't help.

> from a very specific movement born in California long before the current AI wave

Can you be more specific? This is new to me, but I'm not familiar with Californian history.


He’s probably referencing effective accelerationism or something associated with the TESCREAL cloud of beliefs

Edit: saw the other responses. I don’t think effective altruism was the right answer. Effective accelerationism, which came out of effective altruism, has all the ideas about human extinction and needing to develop AGI at all costs to save the species insanity.


Effective Altruism. Also the related Bay Area group known as the "rationalists". Effective accelerationism, while seemingly opposed to EA, is in fact the flip side of the same coin. Look up the term TESCREAL.

Members of these groups are deeply embedded and heavily represented within top AI companies. Anthropic is particularly impacted, as its leadership is almost entirely made up of EAs. One of EA's goals has been to get EAs hired at the major AI labs so that they can influence AI's development. If you ever hear people discussing their personal P(doom), you're listening to a discussion topic originated by rationalists.


Effective Altruism: https://en.wikipedia.org/wiki/Effective_altruism

It has some interesting ideas, and also gave us people like Sam Bankman-Fried.



After searching the closest I got was "Effective altruism". Is that what you tried to say?

Edit: Another comment suggests Effective accelerationism.

America is a stage for the world. Nobody knows or cares about drama happening in European tech companies.

I say this neither negatively or positively, it's just that US news is, for now, the only international news, in both tech and politics.


Which is itself a side effect of the US media treating most news as a spectacle, combined with the US (historically, but especially currently) being a phenomenally good place to be incredibly rich because much of the government will in a way that many developed nations would not allow.

Because they have the most advanced models.

They have the most creditors, we’re at the top of the S-Curve, and inference margins have a lot of room to contract (and it’s not obvious that A\ or OAI are competitive against DeepSeek in that domain).

Because Anthropic and OpenAI are the primary drivers of the AI space?

Every company that is not OpenAI or Anthropic is sufficiently behind the frontier to feel ethically shielded from the weight of advancing the frontier.

wow. that's really quite backwards. the more money you raise and the more money you want, the bigger the story you have to tell. apparently after 1T you've got to raise the stakes to extinction level event.

"it's just marketing" cool story bro

Capital concentration, they have access and lots of control over the media, their CEOs made themselves public personalities, they for some reasons decided to cosplay as Bond villains, they are linked to Trump (and lot of people hate Trump). Just a few reasons, I’m sure we can think of more

Every now and then I look through the cables and take out the ones I no longer have hardware for. We have a cargo-tram every couple of months where you can bring things for disposal that don't go to normal garbage or recycling. Supposedly they recycle the cables but I suspect that means incinerating them (to generate electricity) and collecting the metal after.

I never heard of muse the band. I never heard of meta's muse either.

Muse puts on a killer live show. Don't miss them if they come to town.

Well now you've heard of both, so their marketing is working!

Im so cool that the only social network I use is hacker News and I don't even use that - I use hckrnews.com!

Does it really? Or is it that they're all pretty much good enough and so you just go with what's cheapest or what you're used to?

For example, in IntelliJ I can switch between maybe a dozen models with a drop-down but the only time I do it is when whatever model I'm currently using has an outage.

Another example, our product has some ai features (not coding related). I use spring-ai and so I can change models just in the config file. But I stick with deepseek because it's more than good enough and is super cheap.


It’s pretty well established by now that harness matters as much as a model. Even if a model is smart enough to work around harness’ limitations, it may take it way more time, context and money.
