NASA solar panels

[Magic Star]

Hi guys, do anyone have experience with those panels? Are they better than the rest of the competition and would the price justify the little extra you have to pay for?
On ebay you find tons of semi flexible mono solar panels and NASA is about 50% more expensive. You get a NASA 20w solar for about £100 but yo find no brand 40w for £90. NASA looks very well build but I don't know if the no brand are very different.

Any thoughts?

I wouldn't touch semi-flexible unless there's absolutely no way to fit rigids. Every one I've had (three or four different makes) has degraded badly in UV and given up to ghost (typically, tantalisingly, just out of warranty). Rigids just seem to go on for ever.

I've just bought the 20 amp one and I am really impressed. I use it to charge the fridge battery. Keeps it topped up perfectly

Yes I have 2 x 20W NASA panels with a regulator to keep the leisure batteries (2 x 85ah) charged and they seem fine.

I've had 3 semi flex panels which have not degraded. No knowledge of the nasa ones - i bought cheap of ebay.
