Key Points

    Walmart is suing Tesla for breach of contract after Tesla solar panels ignited atop seven of its stores.
    Tesla and Walmart have been partners on clean energy initiatives for years; more than 240 Walmart stores have Tesla solar systems installed.
    Walmart has also pre-ordered at least 45 Tesla electric semi-trucks to add to its vehicle fleet.

Walmart sues Tesla after solar panels on stores catch fire

Walmart is suing Elon Muskís electric vehicle and clean energy company after Tesla solar panels atop seven of the retailerís stores allegedly caught fire, according a court filing.

The Walmart suit alleges breach of contract, gross negligence and failure to live up to industry standards. Walmart is asking Tesla to remove solar panels from more than 240 Walmart locations where they have been installed, and to pay damages related to all the fires Walmart says that Tesla caused.

The Walmart suit, filed in the state of New York, alleges that: ďAs of November 2018, no fewer than seven Walmart stores had experienced fires due to Teslaís solar systems - including the four fires described above and three others that had occurred earlier.Ē The filing details evacuations, damaged property and inventory.

Teslaís stock dropped more than 1% after hours on the news.

Walmart claimed, among myriad complaints, that ďTesla routinely deployed individuals to inspect the solar systems who lacked basic solar training and knowledge.Ē In the suit, they also alleged that Tesla failed to ground its solar and electrical systems properly, and that Tesla-installed solar panels on-site at Walmart stores contained a high number of defects that were visible to the naked eye, and which Tesla should have found and repaired before they led to fires.

Tesla has been trying to revive its solar business of late.

On Sunday, CEO Elon Musk announced in a string of tweets that customers in some states can now rent Teslaís residential, solar rooftop systems without a contract. The offer is available in six states, and will cost customers at least $50 a month (or $65 a month in California).

Although Musk touted the ease of cancelling a rented roof at anytime, the fine print on Teslaís website mentions a $1,500 fee to take out the solar panels and restore the customerís roof.

In the second quarter of 2019, Tesla installed a mere 29 megawatts of solar, a record low for the company in a single quarter. In its heyday, Teslaís solar division (formerly SolarCity) installed over 200 megawatts in a single quarter.

What ever happened to Teslaís Solar Roof tiles?

When Tesla acquired SolarCity in 2016 for around $2.6 billion the deal caused controversy that continues to this day.

SolarCity was founded and run by Muskís first cousins, Peter and Lyndon Rive. Prior to Teslaís acquisition, Musk owned about one-fifth of SolarCity stock, which was valued around $575 million at the end of 2015. While SolarCity had been a successful solar installer in the prior decade, its stock was plummeting, and debt had ballooned to $3.4 billion before the deal closed.

In an investor presentation meant to drum up support for the acquisition, Musk showed off what appeared to be sleek, glass solar roof tiles. Rather than bulky panels, they looked like premium shingles. The solar roof tiles are still not widely distributed or mass-manufactured.

Walmart and Tesla did not immediately respond to requests for comment.

Yup larger industrial solar still uses the high voltage strings and central inverters so you have high voltage dc traveling long distances to a centralized inverter. Its way cheaper but prone to some nasty ass dc arcing should anything go wrong. Here all those dc wire runs have to be physically protected using conduit or metal screening but those are not standards all locations have. The damn rodents love to chew them some PVC. There are a whole pack of changes that have happened in the last 5 years to content with these issues in the industry. I would only install micro inverters on my roof.  They transform the dc from the panels to ac which is less prone to arcing and trips immediately. The industry is slowly going that way for roof mounted arrays. 
If its important then try something, fail, disect, learn from it, try again, and again and again until it kills you or you succeed.

I was counting on some expert commentary from you on this one NF. :)

When you say "High Voltage DC" what are we talking here?  72V More?

For string inverters usually 400 to 600 volts dc... scary shit! During the wild west days of subsidized solar speed was all that counted workmanship and smart equipment selection not so much. The industry has been shaking out the last few years

YEESH!  That IS scary shit! 😨  You could probably arc 100' with that.

Yup. So imagine 150 to 200 ft of the stuff 10gauge wire with a single PVC sheath zap strapped to the back of the panels sitting on triangular racks on roofs. No panel by panel monitoring so you just know how the whole string is doing. No arc fault function in the older systems so a frayed wire can just happily arc all day long and dc arcs continually and won't short like ac. Poor maintenance because it was the put em up fast days, a badly trained workforce because it was growing so damn fast... poor documentation again for speed and poor electrical  inspection because the industry is moving way way faster then the regulators...
What could go wrong?

It amazes me that a company like Walmart would contract for something like that.  One would think they have a whole department full of their own electricians.  I'm an amateur and even *I* know better than that!  I've sent lightning bolts 3-4' long just with 36V.  That is just plain stupid.

This Futuristic Car Is Powered By Hydrogen And Only Lets Out Water

2019/08/20

By Mayukh Saha / Truth Theory
Weíve come a long way since we first started using hydrogen fuel cells to power cars. It was only about thirty years ago that they could be made small enough to be placed inside a car. Over time, theyíve become slightly more cost-effective and availability has increased but these cars are still not in the mainstream. Manufacturing them is an expensive endeavor which can also get cumbersome.
