Yes, caution is always warranted, when you have relatively large power sources in certain situations,

Amazon warehouses’ rooftop solar fires signal a threat to renewable energy

6 Amazon warehouses, 6 solar fires: Solar panel fires and explosions at Amazon facilities were linked to poor installation practices. The problem underscores the need for more cleantech training and safety.

Does that sort of indicate that amazon not only sell stuff cheap, but also buy theie stuff cheap?

More likley employing cowboys to throw their big shed up with the box tickin* solar on top.

Not another energy thread! Hasn't this subject been done to death, killed, hung drawn and quartered, bludgeoned to death, etc. etc.

Don't forget keel hauling, Andy

Realistically Amazon will use experienced contractors and abide by all the local planning rules.
Companies of that size do things by the book.

Seen the apple solar roof?

It’s 6MW or something. Came up on my feed yesterday.

There a 4mw shortfall I’m their use so they use something else for that. Not sure. Can’t remember.

I don’t normally watch that crap but it was actually quite interesting how that ‘spaceship’ workes

I doubt Amazon would go cheap on the installations, it costs them an utter fortune when one fails.
I suppose they get subsidies for their solar uptime, and bad publicity as a promoter of green energy.

Amazon took all U.S. solar rooftops offline last year after flurry of fires, electrical explosions

While Amazon tries to go green, the company has encountered numerous challenges with solar panels at various warehouses.

Most of the solar fires are caused by water ingress into things like DC isolators or crap connections causing arcing, look at page 24 onwards

The MC4 connectors used on solar panels are crimped, not the best crimp type in my opinion. OK if done properly but easy to get wrong. These are the ones.

On the water ingress side, a lot of the inverters and isolators are IP65, so theoretically can be installed outside in a sheltered location. But bad installation can ruin that rating. That's why I'm installing them in an outside shed. Firstly, keeps them dry, secondly, if there is a fault and it goes up, its 15m from the house.

Where I work we have a huge warehouse, the roof has been covered in PV for quite a few years, never had an issue. I know the guy who runs the place, he retired last week. He doesn't employ numpties, they are off site in minutes.
