Maybe panels are getting so much cheaper because the newer TOPCon ones are replacing them?I am very suspicious of these new panels because of their low price and Wills comment on the lower weight.
We need some ProjectFarm type testing on these panels to see how durable the frame and the glass and mainly the seals on the frame edges. The whole thirty year warranty thing means nothing. Even if they lasted 20 years I would have long upgraded them. Not to mention that I doubt in 10 years time these companies will exist.
What kind of testing should I do to them? Throw rocks at them and twist them?I am very suspicious of these new panels because of their low price and Wills comment on the lower weight.

Throw junk NMC batteries at them to see whether they break or the NMC blows up first.What kind of testing should I do to them? Throw rocks at them and twist them?
No need for you to spend your time doing that... I heard that FedEx offers that type of testing already...What kind of testing should I do to them? Throw rocks at them and twist them?
Once mounted, there won't be any twisting other than shipping and handling. Twisting might actually be beneficial for vehicle mounted systems, not a negative feature to worry about.What kind of testing should I do to them? Throw rocks at them and twist them?
Just use your standard testing.What kind of testing should I do to them? Throw rocks at them and twist them?
You should see what I do when the camera is off. People would cringe so bad hahaJust use your standard testing.
Integrarack has some crazy test videos. Pulling on them with a forklift with thousands of pounds. The big issue is hail because it can crack it. But I don't think anything else is going to hurt panels.Once mounted, there won't be any twisting other than shipping and handling.

Up here along Lake Superior I have seen panels blown off from ground mounts. They were bolted down through the frames, not captured like clamps would be. The bolts actually tore through the aluminum frame. Id like to see some frame testing from manufacturers. In high wind areas I like the REC panels, they tend to put extra effort into their frames and add 2 bars across the back for strength.
Another topic has been hail. A test would need to be controlled / measurable in some fashion. Like a baseball pitching machine sending a known weight at different speed settings might work?
Fantastic Price, what makes them “ Tier 1?”
Did they say what panels they were pulling on?Integrarack has some crazy test videos. Pulling on them with a forklift with thousands of pounds.
Yeah I've just noticed some differences between panel brands in regards to the aluminum frame. For instance the Canadian Solar panels have a great snow loading but the frames seem to be brittle. They were the ones that blew off with pieces of the frame still under the nut on the mount. Not torn or bent or anything, just broke. Seen 2 separate occasions, both were Canadian Solar.The big issue is hail because it can crack it. But I don't think anything else is going to hurt panels.
Oh, Puerto Rico during hurricanes can kill panels.
Out here in the desert we have huge solar farms I drive past every single day and the winds they have to handle is crazy.

The nice thing with those is VOC is only 37V so can put a bunch in a string.Just order the Hyperion solar panels after every body mentioned them. Would be awesome to compare them to the Aptos. Seem to be very similar panels.

Bloomberg publishes a Tier 1 list of manufacturers that is based on a variety of criteria, not only in regard to the panel but also the financial standing of the manufacturer and the volume they are producing per year. As far as I understand, most utility scale or large projects require in the contracts for the panels to be off the Tier 1 list. I've heard arguments, however, that it's an inappropriate "end-all-be-all" because they don't do as much mechanical testing.Fantastic Price, what makes them “ Tier 1?”

Yes, they're shipping across the US. Had a long conversation with them. I mentioned this forum and Will's review videos. @Will Prowse they said they are bringing a new 5KWH rack style battery to the market and were gunna reach out for review.I tried to throw a pallet in the cart to see what the shipping would be but it only offers me free pickup. Do they ship? Have you bought from them?
Has anyone used this vendor? Are they legit?Based in Denver Colorado - check out: https://ark-usa.io/

Perhaps a hail test.What kind of testing should I do to them? Throw rocks at them and twist them?
