A Journal of Light Construction editor had a fire in his SolarCity panel set-up as well, and had a hard time getting it sorted out. https://www.jlconline.com/how-to/electrical/solar-panel-fire... and here's a follow-up: https://www.jlconline.com/how-to/electrical/solar-panel-fire...
Didn't Solar City rely on local installation firms?
>totaling hundreds of thousands of dollars in out-of-pocket losses, Walmart said in the lawsuit. This amount is immaterial for each party involved.
The fanboyism is ridiculous for grown adults.
So many apologists on this site its hilarious. I guess Walmart is against climate change! https://twitter.com/sama/status/1130913917864034304?s=19 At won't point will you hear something that makes you doubt this company? Anything?
If you think everyone or even most people commenting on this site are pro-Tesla, I think you're not really reading HN. Either way, the Tesla debates I see are a whole lot like people debating over petty bs like celebrity news, so I usually stay out of them.
The "influencers" are, and if you don't think so you aren't paying attention. Look what they say on Twitter. I posted a link in another comment, but miraculously it disappeared.
It happened with Theranos too. People of "high reputation" on this very site claimed everything was "FUD", that if you were against the company it was because you didn't want to see a young woman succeed in Silicon Valley. Then it turned out to be a fraud. And yet these people are still reputable here, after ridiculous commentary. It says a lot about the community, unfortunately.

sarcher's example of JLC. It does look like a faulty optimizer, which is a DC electronic for each panel. As for Walmart, it's a lot to unpack. > dozens showing hazardous problems such as loose wiring and “hot spots” on panels, according to court papers filed in New York State Supreme Court. Loose wiring? A lot of setups are mostly plug and go. If they had to splice one wire, it's only a minute process to do and if th…
The optimizer consists of MOSFETs, an inductor, and a microcontroller. The circuit is pretty similar to a BLDC motor controller. The circuit relies 100% on the microcontroller outputting the right signals, otherwise a mosfet gets stuck on (causing overcurrent, and burning out). Little boxes like that are hard to waterproof and make resistant to repeated temperature fluctuations. My guess is some water went in and sho…
I'm not an E.E. but does that apply for DC optimizers? Older optimizers had no AC conversions in them.
> Little boxes like that are hard to waterproof and make resistant to repeated temperature fluctuations.
Hmm. I never checked to see if the warranty for the optimizers are 20 years. The panels are but I'd be surprised to see the optimizers be less than 20. Most, non-cheap, optimizers do have insulation to prevent moisture from getting in.
> It's just as likely to happen on a de-energised panel too - the optimizer is still connected, and the sun is still shining.
Based on your description, that makes it a possibility. Why aren't the optimizers equipped with some type of regulator to prevent output in situations like this?
"whistleblower123456 1 point · 7 months ago If you want the truth here it is. Tesla has installed millions of defective amphenol connectors all over the u.s. These connectors are catching fire and burning down homes and businesses. They are hiding it with something called project titan where they are hiring thousands of people just to replace connectors. The problem is that they are testing it with infrared cameras to see if the connector heats up and only then replacing it. These connectors are defective meaning just because it passes one day it does not mean it wont fail the next even after testing. Tesla refuses to replace all of these connectors betting on insurance to cover any fires and only looking at homes when their monitoring platform reports arc faults. This is why they are dismantling the solar division with layoffs. Right now if you have tesla installed on your roof you may have a ticking time bomb ready to kill you in your sleep. If you have it on your business same thing. Don't believe me, google walmart fires. If you have tesla stock better prepare to sell it because when this gets out it is going to crash. They need to do the right thing and shut off all systems with these connectors and replace them with mc4. They wont because it would cost them hundreds of millions to do and hundreds of thousands of dollars on lost production. Do the right thing Tesla."

Compared to your average SV outfit like Tesla? It most likely is.
You said, with zero evidence to back it up. Unsubstantiated anti-Musk astroturfing is really tired and boring
