Local seller with Boviet 305W panels. Are these OK?

Dude is selling them for $150 per.
Seems to be this one:

Aurora Solar: The World's #1 Solar Design Software

The #1 solar software to design and sell advanced PV systems. See why installers use Aurora to create over 100,000 PV designs every week.

Seems like it might be an older model, maybe around 2017. Seller says they are "overstock". New model may be 260W.

If it's a discontinued model, are they still worth it? I haven't found much just googling them.

I have the room on the roof of our kind of large camper box for a few large panels like these.

15.72% peak efficiency is decent for $.50/ watt, 12-volt panels often cost three times that.
Most panels are designed to resist high winds, hail and fire, so putting them on a vehicle is not too taxing. Higher voltage panels need a MPPT or a buck converter, but that is pretty efficient and means you gather useable power for more of the day. The price means that you can get a good controller with what you didn't spend on RV-panels. Boviet is a Vietnamese company that makes a lot of panels, the 90% power output warranty is twice as long as most, so likely a pretty good product.
