Powitt 450w bifacial panels anyone familiar with this brand?

So I've found a very local supplier of panels (literally 15 minutes down the road is the 5th largest supplier in Thailand) they have 450w bifacial branded Infosat (well known satellite TV box brand in Thailand) but from research they seem to be rebranded and manufactured by Powitt.

My googling hasn't really thrown up many results other than the manufacturers speel but they come with a 12/25 year guarantee (no idea which it actually is) the price is good and supporting a local supplier is nice.

Anyone here have any idea about this manufacturer?
It seems that alot of their dealings seem to be supplying other companies for rebranding.

Don’t have super useful other info, besides to share that IMO solar panels are a commodity, and I’m with the majority of folks here that don’t go for name brand panels with the latest extra 1% efficiency and reduced 25 year degradation curve.

Besides that, if you visually look at the cells embedded inside the panel you can infer what type they used, to confirm the spec sheet to an extent. Cell type, generation, expected output current, etc. And if you can test one before taking delivery that further derisks things (but usually in the U.S. people only do that for used they get from out the random back of a warehouse or truck)

Cheers for the reply, though from what I've seen many people do go with Longi, JA, EVE and so on.

Sorry I'm fairly new to solar and haven't had much experience with different panels/cell types so my eyes can't differentiate, no rating plate has been posted on their listing and I haven't been able to go physically look at the panels (a damn $1 rubber grommet fell off the transmission linkage on the car so it hasn't been able to move in days till a replacement is delivered)


This is the posting they work out to be $68 per panel which is middle ground for panel price here.
