Are all panels basically the same now?

I'm looking at two different panels - both 500w and both about £80/panel with free delivery.  Is there likely to me any real difference between them?

(One is the LONGi Hi-MO X6 and isn't in stock, the other is a DMEGC and is in stock)

I’d buy glass / glass vs glass / foil, as these have much better longevity.

If you are getting the bifocal version they are glass / glass. Also watch as I found the datasheet and actual panel size where different, datasheet saying they were bigger (long side) than actually size.

If going in trays this is of vital importance. If on a rail system, not so much, but a very good point!

If the panels are going on a roof, how does the bifacial part work?

It doesn’t. You just discount it.
