Has anyone purchased a Fivsta Sola panel from Amazon and have experience with them? Looks like they're a relatively new brand on Amazon and they have some interesting panel sizes (squarish, as well as long/skinny) compared to others, as well as bifacial options. The 200w squarish bifacial is basically the perfect size for my application and has me very interested. I don't like that there doesn't seem to be any datasheets though, and I can't find any similar panels on the Chinese reselling sites either (suspicious). On paper, the stated specs are on the high end of efficiency (0.132w/sqin). That's better than a decent chunk of residential panels, but not outside the realm of feasibility.
Edit
The non-bifacial 200w panel is more in line with other non-residential panels (0.121w/sqin). I bet the 200w bifacial used a non-standard test to get to the 200w rating.
End edit
I'm a bit hesitant to trust a newer brand. Skimming through the Amazon reviews, the vast majority were vine reviews of a 20w panel so you can't really trust them. The non-vine reviews are generally positive, but are light on technical details. A few reviews mention cracked glass and some improperly sealed junction boxes.
Any reviews out there on the forums?
